Chapter 1 - Introduction
1.1 General
The TD Series is a digitally programmable solid state reduced voltage
soft starter. Its six SCR design features a voltage/current ramp with an
anti-oscillation circuit for smooth load acceleration. The SCRs are sized
to withstand starting currents of 500% for 60 seconds (compared to
350% for 30 seconds from other manufacturers). The TD Series features
smooth, stepless ramp control which reduces motor inrush current and
excessive wear on the mechanical drive train components. In addition to
having easy to understand diagnostic LEDs, the TD Series includes a
programmable keypad for setting operating parameters for the ideal
starting cycle. Starting torque, ramp time, current limit, dual ramp, and
decel control are standard features on the TD Series. By simply adjusting
the unit’s starting torque, ramp time and current limit functions, the starting
electrical characteristics of the motor can be matched to the mechanical
characteristics of the drive train for controlled acceleration of the load.
The TD Series includes solid state electronic overload protection in
addition to numerous other protective features. It is factory wired for 120
VAC control voltage and two or three-wire start/stop control (Units can
also be ordered with 240 VAC control voltage if required). Programmable
auxiliary contacts and provisions for interlocking are also included.

Chapter 2 - Installation

2.1 Receiving and Unpacking

Upon receipt of the product you should immediately do the following:
• Carefully unpack the unit from the shipping carton and inspect it for
shipping damage (if damaged, notify the freight carrier and file a
claim within 15 days of receipt).
• Verify that the model number on the unit matches your purchase
order.
• Confirm that the ratings sticker on the unit matches or is greater
than the motor’s HP and current rating.

2.2 Location
Proper location of the TD Series is necessary to achieve specified
performance and normal operation lifetime. The TD Series should
always be installed in an area where the following conditions exist:

• Ambient operating temperature:

Chassis unit: 0 to 50°C (32 to 122°F)
Enclosed unit: 0 to 40°C (32 to 104°F)
• Protected from rain and moisture
• Humidity: 5 to 95% non-condensing
• Free from metallic particles, conductive dust and corrosive gas
• Free from excessive vibration (below 0.5G)
• Open panel units must be mounted in the appropriate type of
enclosure. Enclosure size and type must be suitable to dissipate
heat generated by the soft starter. Contact factory for assistance in
sizing enclosures.

2.3 Initial Unit Inspection

• Make a complete visual check of the unit for damage which may
have occurred during shipping and handling. Do not attempt to continue
installation or start up the unit if it is damaged.
• Check for loose mechanical assemblies or broken wires which may
have occurred during transportation or handling. Loose electrical
connections will increase resistance and cause the unit to function
improperly.
• Prior to beginning the installation, verify that the motor and TD unit
are rated for the proper amperage and voltage.

2.4 Warning!
Do not service equipment with voltage applied! The unit can be
the source of fatal electrical shocks! To avoid shock hazard,
WARNING
disconnect main power and control power before working on
the unit. Warning labels must be attached to terminals, enclosure
and control panel to meet local codes.

2.5 Mounting and Cleaning

When drilling or punching holes in the enclosure, cover the electrical assembly
to prevent metal filings from becoming lodged in areas which can cause
clearance reduction or actually short out electronics. After work is complete,
thoroughly clean the area and reinspect the unit for foreign material. Make
sure there is sufficient clearance (six inches) all around the unit for cooling,
wiring and maintenance purposes. To maximize effective air flow and cooling,
the unit must be installed with its heat sink ribs oriented vertically and running
parallel to the mounting surface.

WARNING Remove all sources of power before cleaning the unit.

In dirty or contaminated atmospheres the unit should be cleaned on a regular

basis to ensure proper cooling. Do not use any chemicals to clean the unit.
To remove surface dust use 80 to 100 psi, clean, dry compressed air only. A
three inch, high quality, dry paint brush is helpful to loosen up the dust prior
to using compressed air on the unit.

Chapter 3 - Motor Overload Protection

3.1 Solid State Overload Protection
The TD Series Starter provides true U.L. listed I2T Thermal Overload Protection
as a built-in function of the main digital processor. For maximum protection it
simulates the tripping action of a bimetallic overload relay, with the accuracy and
repeatability of a digital control system, yet is adjustable over a wide range and
can be easily programmed for different trip curves.
3.1.1 Thermal Memory
The TD Series microprocessor uses a sophisticated “Thermal Register” to keep
track of motor heating and cooling over time regardless of the starter’s power
status. The TD Series does not “forget” that the motor has been running even if
power to the starter is turned off and back on. Continuous overload protection is
provided based on the true thermal condition of the motor.
3.1.2 Thermal Capacity
The Thermal Register is displayed as a percentage. This percentage is the motor’s
remaining thermal capacity. The percentage value begins at 100, showing that
the motor is cool. As the motor heats up or moves toward an overload condition,
the percentage begins to drop. The Thermal Capacity is derived from the
programmed motor nameplate Full Load Amps (FLA) in Function F001, the Service
Factor rating in Function F002, and the Overload Trip Class in Functions F003
and F004. Setting these functions to the proper values will provide maximum
protection yet eliminates nuisance tripping.
3.1.2.a Motor Full Load (FLA) Setting
Use Function F001 to enter motor FLA as indicated on the motor nameplate. (Do
not calculate for service factor, this is programmed separately in F002).
Note: If F001 is left at the factory default, the unit will not operate. If the
user attempts to start the TD without entering the motor nameplate
FLA into this Function, the TD will Fault, and the display will read
“nFLA” (for no Full Load Amps).
3.1.3 Disabling the Overload Protection
The Overload Protection feature can be disabled if absolutely necessary. When
using external devices such as Motor Protection Relays or when the TD Series
is wired downstream from an existing starter, this feature can be disabled to
prevent conflicts with external overload protection devices. When the TD Series
is controlling multiple motors, Overload Protection must be disabled. Individual
thermal overload relays must be installed on the motor leads going to each
motor. To disable the Overload Protection function, use F005. (See Section 5.)
WARNING Do NOT disable Overload Protection unless another Thermal Overload
Protection device exists in the circuit for all three phases. Running a
motor without Overload Protection presents serious risk of motor damage
or fire.
3.1.3.a Manual Reset
The factory default setting is Manual Reset. This means that when the Overload
Trip is activated, the starter cannot be restarted without pressing the Reset key.
The Overload Trip will not reset until the motor cools down. The Manual Reset
function is also “trip free”. Holding in the Reset key will not prevent the Overload
Trip from activating and protecting the motor.
Note: When the Overload Trip activates, the Overload LED will glow
solid. When the motor cools down, the LED will begin to flash,
indicating that the Overload Trip can be reset.

TD - Series

TD Series Digital Solid State Soft Starter 48 - 1250A

3.1.3.b Automatic Reset

If Automatic Reset is necessary, change from Manual Reset to Automatic Reset
by using Function F005. (See Section 5 for details). In this mode, a 3-wire control
circuit will be capable of restart when the TD Series has reset itself after the cool
down period.
Two-wire control systems may restart without warning when Auto Reset
is selected. Extreme caution should be exercised. To prevent automatic
restarting with two-wire control systems, use external interlocking to
provide sufficient warning and safety to operators. A Warning Label (such
as the one provided in the packet with this manual) must be placed to be
visible on the starter enclosure and/or the equipment as required by local
code.

WARNING MOTOR CONNECTED TO THIS EQUIPMENT MAY

START AUTOMATICALLY WITHOUT WARNING

3.2 NEMA Class Trip Curves

The TD Series Soft Starter provides six NEMA Class trip curve options: 5, 10,
15, 20, 25, and 30. Program the appropriate curve according to the characteristics
of your motor and load.
NEMA Class trip curves are based on a common tripping point of 600% of rated
current. Curves vary by the amount of time before the unit trips. As an example,
a Class 20 curve will trip in 20 seconds at 600%. The factory default setting of
Class 10 will trip in 10 seconds at 600%.
3.2.1 Dual Overload Trip Curves
The TD Series Soft Starter provides two separate Overload Trip Protection Curves,
one for starting and one for running conditions. Programming a higher NEMA
Class overload during start (ramp-up) will eliminate nuisance tripping in higher
inertia or high friction loads.
The starter’s At-Speed detection circuit determines when the motor has reached
full speed based on closed loop feedback signals. When the At-Speed condition
is reached, the overload trip curve will shift from the Start to the Run level, as
programmed in Functions F003 and F004. See Section 5 for programming details.

Chapter 4 - Connections
4.1 Power Connections
Connect appropriate power lines to the unit input terminals marked L1, L2, L3.
Avoid routing power wires near the control board. Connect the motor leads to the
unit terminals marked T1, T2, T3. Refer to NEC standards for wire length and
sizing. Never interchange input and output connections to the unit. This could
cause excessive voltage in the control logic circuit and may damage the unit.

WARNING Never connect power factor correction capacitors on the load side of the
unit. The SCRs will be seriously damaged if capacitors are located on
the load side.

The unit cannot be tested without a motor or other test load connected to the
load side of the unit. It may be necessary to use a load bank to test the unit
without a motor. Note that line voltage will appear across the output terminals if
there is no motor or load connected to the unit. In areas where lightning is a
significant problem, stationary air gap lightning arrestors should be considered
and utilized on the input power source.

5.3 Display Modes

There are three modes of display: the Status Display mode, the Program mode,
and the Fault mode.
5.3.1 Status Display Mode
The Status Display Mode displays three phase motor current information and the
thermal capacity remaining.
Status mode:
• [0000.] The initial display on power up is four digits and the decimal. This
indicates the motor current for Phase A of the motor.
• [0000] Scroll up to display four digits only (no decimal). This indicates
the motor current for either Phase B or C. While viewing Phase A, press
the UP arrow once to view Phase B or twice to view Phase C current.
• [H000] Scroll up to display the “H”. This indicates that this value is the
remaining thermal capacity of the motor (as a percentage i.e. H070 =
70% remaining thermal capacity)

Enabling Password Protection / Parameter Lock

The TD Series Soft Starter is shipped with the Customer password disabled
(F060 = 0). If it is necessary to prevent parameters from being changed
inadvertently, set the password in function F060. See Appendix 4 for details.
The display of a customer password is encrypted. If you do not have a record of
the password and need to gain access, contact TOSHIBA Tech Support. Be
ready to provide the TD Series serial number and the four digits in the encrypted
display. If the display reads “Err” when the READ/ENTER key is pressed, the
parameter lock is enabled.

Changing a Function’s Set Value

Use the UP arrow key to increment the value of the flashing digit. Use the DOWN
arrow key to decrement the value of the flashing digit. Use the LEFT or RIGHT
arrow to select the next digit to be altered. Values can only be changed within
the Adjustment Range of the function parameter.
Storing the Altered Value of a Function
Once the desired value is displayed, press the READ/ENTER key. This stores
the value in memory. The readout momentarily displays [ END] and then returns
to another function code.
NOTE: If the Fn key is pressed BEFORE the READ/ENTER key is pressed, the TD Series
Starter will not store the selected value in memory.

The Fault Display Mode provides information to the operator when a fault occurs
or when the operator wishes to review fault history. Refer to Section 7 for details.
Fault codes are three-digits in length and are displayed in alpha characters. The
first and second characters (reading left to right) are the initials for the applicable
English-language fault name. The third or right-most character can be either A,
C, or D to denote when the fault occurred. A denotes Acceleration. C denotes
Constant speed. D denotes Decel.

5.5 Function Descriptions

The unit is set at the factory with typical starting characteristics that perform well
in most applications.
Note: Customer must program motor FLA (F001) for unit to operate.
5.5.1 Motor and Overload Function Descriptions
F001 = Motor FLA
Factory Setting = 0
Range = 50 - 100% of Unit Max. Current.
Set the value of this function to the motor nameplate Full Load Amps
(FLA). Adjustments for service factor are not necessary when
programming this function. (See note below). If the motor nameplate
FLA is not available, use typical values as shown in NEC, NEMA
standard MG-1 or other reputable third party source (motor manufacturer,
etc.).
Note: To prevent adjusting the settings beyond the starter Max Amp rating, the range
of adjustment for the Motor Nameplate FLA will vary to reflect the Service
Factor as programmed into F002. At the default setting of 1.0SF, the full range
of adjustment from 50 - 100% of the Max Amp rating is available. For example
F002 = 1.15 to reflect a 1.15SF, the maximum FLA programmable into F001 will
be limited to 85% of the starter Max. Amp rating (100% - 15%).

- 20 -
TD Series Digital Solid State Soft Starter 48 - 1250A

F002 = Service Factor

Factory Setting = 1.0 S.F.
Range = 1.00 - 1.30
Set value according to the Service Factor (SF) data provided on the
motor’s nameplate. This value affects several protection features so it
must be accurate. Setting the SF too high may result in motor damage
in overload conditions. Setting SF too low may cause nuisance trips.
F003 = Overload Class During Start
Factory Setting = 10 (Class 10)
Range = 5 - 30 NEMA / UL Class
Set value to the motor protection overload class required for the
application. It is recommended that you try the factory setting first. (If
possible, keep values for F003 and F004 the same.) Increase F003
above F004 only if nuisance tripping occurs during start. See Section
3.2 for details on trip curves.
F004 = Overload Class During Run
Factory Setting = 10 (Class 10)
Range = 5 - 30 NEMA / UL Class
Set value according to the instructions provided by your motor /
equipment manufacturer. This trip curve will not be enabled until the
motor has reached full speed.
F005 = Overload Reset
Factory Setting = 0 (Manual)
Range = 0 - 2
Set value to determine starter behavior after an overload condition has
cleared.
When set to 0 = Manual, the operator must press the Reset key
before restarting the motor. Once the motor windings have cooled
sufficiently AND the Reset key is pressed, the unit will accept a restart
command.
When set to 1 = Automatic mode, and once sufficient time has elapsed
allowing motor windings to cool, the motor will be restarted upon a
start command.
WARNING Setting F005 = 1 (Automatic) may present significant
operational risk.
When set to 2 = Disabled Overload, a separate external thermal
overload protection device must be in the circuit.

5.5.2 Starting Mode

The TD is capable of several different starting modes, but is set from the factory
for the most common applications. A second ramp profile is available for use
should you need it but unless wired to do so, the TD defaults to Ramp 1. This
section describes functions for Ramp 1, with references to function numbers that
do the same thing for Ramp 2 if required. Refer to Appendix 2 for a detailed
description of the differences in Ramp Profiles and their uses.
F010 = Ramp Profile Selection
Factory Setting = 1
Range = 1 - 4
This Function selects the type of Ramp Profile desired. Ramp profiles
can be either Voltage Ramp or Current Ramp. See Appendix 2 for
details. Each Ramp Profile consists of 3 settings:
Initial Torque, Ramp Time and Maximum Current Limit
Because there are two ramps available, there are 4 settings to cover
the combinations of profiles possible. If you are not using the 2nd
ramp, the TD will ignore all settings in reference to Ramp 2.
Select Voltage Ramp by setting F010 = 1 (factory default)
When Voltage Ramp is selected,
Set Initial Torque with F011 (see below)
Set Ramp with F013 (see below)
Set Maximum Current Limit with F014 (see below)
Or;
Select Current Ramp by setting F010 = 2
When Current Ramp is selected,
Set Initial Torque with F012 (see below)
Set Ramp Time with F013 (see below)
Set Maximum Current Limit with F014 (see below)

Ramp Type
Setting
F010 Ramp 1 Ramp 2

Profile 2 Current Ramp Current Ramp
Selection 3 Voltage Ramp Current Ramp
4 Current Ramp Voltage Ramp

F011 = Initial Voltage of Ramp 1

Factory Setting = 60%
Range = 0 - 100%
Sets the initial voltage of ramp 1 when F010 = 1 or 3. The initial torque
level should be set to provide just enough torque to make the motor
shaft begin to rotate while preventing torque shock damage to
mechanical components.
F012 = Initial Current of Ramp 1
Factory Setting = 200%
Range = 0 - 600%
Sets the initial current of ramp 1 (when F010 = 2 or 4). Current
percentages are based on the Motor FLA as set in F001. The initial
torque level should be set to provide just enough torque to make the
motor shaft begin to rotate while preventing torque shock damage to
mechanical components.

TD - Series
- 22 -
TD Series Digital Solid State Soft Starter 48 - 1250A

F013 = Accel Ramp Time of Ramp 1

Factory Setting = 10 seconds
Range = 1 - 120 seconds
Sets the time between the initial torque (set with F011 or F012) and
either the Max Current Limit (set with F014) or full output voltage. Set
time to enable soft starts without stalls. Also consider your motor’s
application. For example, centrifugal pumps may require a shorter ramp
time.
Note: Ramp time is affected by the following conditions:
1. Current limit will extend the ramp time if the motor does not reach full
speed while in current limit mode.
2. Anti-oscillation circuit will shorten the ramp time if the motor reaches
full speed before end of ramp.
F014 = Max Current Limit of Ramp 1
Factory Setting = 350%
Range = 200 - 600%
Sets the maximum motor current that the TD Starter will allow during
ramp 1. This limit applies to both voltage and current-type ramping.
Current will be limited to this setting until either the motor reaches full
speed or the over load protection feature trips (F003). Current
percentages are based on the Motor FLA as programmed in F001.
Once the motor has reached full speed, the current limit feature is
inactive.
For Ramp 2 (user-optional ramp)
This ramp is selected by closing the input on Terminals TB4 - Pins 1
and 3. If this input is left open, the TD will respond only to ramp 1
settings as listed above. Since ramp 2 is always used in combination
with ramp 1, different combinations of ramp profiles can be selected in
F010. Refer to Appendix 1 for additional information.
F015 = Initial Voltage of Ramp 2
Factory Setting = 60%
Range = 0 - 100%
Sets the initial voltage of ramp 2 when F010 = 1 or 4. The initial torque
level should be set to provide just enough torque to make the motor
shaft begin to rotate while preventing torque shock damage to
mechanical components.
F016 = Initial Current of Ramp 2
Factory Setting = 200%
Range = 0 - 600%
Sets the initial current of ramp 2 when F010 = 2 or 3. Current percentages
are based on the Motor FLA as programmed in F001. The initial torque
level should be set to provide just enough torque to make the motor
shaft begin to rotate while preventing torque shock damage to
mechanical components.
F017 = Accel Ramp Time of Ramp 2
Factory Setting = 10 seconds
Range = 1 - 120 seconds
Sets the time between the initial torque (set with F015 or F016) and
either the Max Current Limit (set with F014) or full output voltage. Set
time to enable soft starts without stalls. Also consider your motor’s
application. For example, centrifugal pumps may require a shorter time.
See notes under F013 for more details.

TD Series Digital Solid State Soft Starter 48 - 1250A

F018 = Max Current Limit of Ramp 2

Factory Setting = 350%
Range = 200 - 600%
Sets the maximum motor current that the TD Starter will allow during
ramp 2. (This limit applies to both voltage and current-type ramping.)
Current will be limited to this setting until either the motor reaches full
speed or the over load protection feature trips (F003). Current
percentages are based on the Motor FLA as programmed in F001.
Once the motor has reached full speed, the current limit feature is
inactive.

Section 5.5.3 Jog Mode

CAUTION Continuous use of the Jog feature — either the voltage type (F019) or
the current type (F021) — risks thermal motor damage or nuisance
tripping.
The Jog Function is another user optional feature and is controlled by closing the
input on TB4 Pins 1 and 2. If this input is left open, the TD will ignore all Jog
settings. The Jog feature provides an output from the SCRs only while this input
is closed. It will not continue ramping to full acceleration. This feature can Jog the

Sets the voltage level of the Jog feature typically is used to check
rotation, alignment, or to slowly move a load into position. Jogging at a
set voltage has no current control so the duration of the applied voltage
must be limited to prevent excessive motor heating.
F020 = Time of Voltage Jog
Factory Setting = 10 seconds
Range = 1 - 20 seconds
Set to minimize motor heating during a voltage jog. This setting is the
maximum allowable time for jogging the motor.

5.5.4 Kick Start Mode

Note: Do not use the Kick Start feature unless you determine that you need it. Using
this feature may eliminate many of the mechanical and electrical benefits of
using a Soft Starter.
F022 = Kick Start
Factory Setting = 0 (Disabled)
Range = 0 - 1
Kick Start Kick start applies a “pulse” of voltage to the motor to produce a
momentary “kick” of high torque to break the motor load free from high
friction or frozen components. When F022 = 1, this voltage “pulse”
begins the initial voltage applied in either F011 or F015. Voltage level is
adjusted by F023 and the time duration of the pulse is adjusted by
F024.
F023 = Kick Voltage
Factory Setting = 65%
Range = 10 - 100%
Sets the voltage level of the Kick Start feature. The setting of F023
should be higher than F011 and F015 and high enough to provide a
benefit in the worst starting condition.
F024 = Kick Time
Factory Setting = 0.8 seconds
Range = 0.1 - 2 seconds
Sets the duration of time the Kick Start voltage is applied.

5.5.5 Decel Mode

Deceleration is a feature of the TD Soft Starter which slowly decreases the
applied voltage to the motor when a stop command is given resulting in a gentle
decrease in motor torque. Deceleration provides a way to extend the stopping
time so that abrupt stopping does not occur. Deceleration is useful with centrifugal
pumps, material handlers, and conveyors where abrupt stopping could be
damaging to the equipment and/or load
Note: Decel is THE OPPOSITE of braking. Enabling the Decel feature will make the
motor take LONGER to stop than if it were simply turned off.
See Appendix 2 at the end of this manual for detailed descriptions of typical
applications for the Decel feature.
F025 = Deceleration Ramp
Factory Setting = 0 (Disabled)
Range = 0 - 2
When F025 = 0, the deceleration feature is disabled.
When F025 = 1, the deceleration feature is enabled AND the overload
protection feature, set with F003 and F004, is enabled. Even when the
stop command is received, the starter continues to apply decel voltage.
However, if an overload trip occurs, the starter stops applying voltage
and the motor coasts to a stop to prevent additional motor heating and
potential motor damage.
When F025 = 2, the deceleration feature is enabled and deceleration
will continue even when an overload condition trips.
WARNING Setting F025 = 2 presents significant risk of over-heating the motor beyond
its design limits which could result in motor damage and fire hazard. Do
this only in circumstances where the potential for mechanical damage
outweighs the risk of motor damage.

F026 = Begin Decel Level (BDL)

Factory Setting = 60%
Range = 0 - 100% of line voltage
Use to drop voltage to a level where there is a noticeable effect on
motor torque during decel mode.
F027 = Decel Shut Off Voltage
Factory Setting = 30%
Range = 0 to (BDL -1)%
Sets the level where motor torque during decel is no longer effective.
Always set this function lower than the setting of F026, Begin Decel
Level.
F028 = Decel Ramp Time
Factory Setting = 10 seconds
Range = 1 - 60 seconds
Sets the maximum time for the deceleration ramp to go from the Begin
Decel Level setting (F026) to the Decel Shut Off Voltage (F027). Since
motor heating increases as voltage is lowered, the setting should not
exceed the time necessary to achieve the deceleration effect.

5.5.6 Protection Features

F030 = Current Imbalance Trip
Factory Setting = 0 (Disabled)
Range = 0 - 1
If F030 = 1 (Enabled), starter will trip when the output current between
any two phases exceeds the amount set with F031 for the time specified
with F032.
F031 = Current Imbalance Trip %
Factory Setting = 10%
Range = 5 - 30%
Use to set the trip level for current imbalance between any two phases.
Percentage is based on FLA (F001 setting).
F032 = Current Imbalance Trip Delay
Factory Setting = 2 seconds
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-duration
transients. Using default settings, if the difference in output current
between two phases exceeds 10% of FLA for more than 2 seconds,
the starter will trip.
F033 = Over Current / Shear Pin Trip
Factory Setting = 0 (Disabled)
Range = 0 - 1
If F033 = 1 (Enabled), starter will trip when the output current of any
phase exceeds the amount set with F034 for the time specified with
F035. Can be referred to as a “Shear Pin Trip” and can be used to
Over Current Trip protect mechanical components from breaking due to jammed loads.
(F033 = 1) F034 = Over Current Trip %
Factory Setting = 125%
Range = 100 - 300%
Use to set the trip level for an over current condition for any phase.
Percentage is based on FLA (F001 setting).

TD - Series

F035 = Over Current Trip delay

Factory Setting = 1 second
Range = 1 - 20 seconds
Provides a time delay to prevent nuisance trips from short-duration
transients. Using default settings, if the output current of any phase
exceeds 125% of FLA for more than 1 second, the starter will trip.
F036 = Under Current Trip
Factory Setting = 0 (Disabled)
Range = 0 -1
If F036 = 1 (Enabled), starter will trip when the output current of any
phase drops below the amount set with F037 for the time specified
with F038. Fault condition is often referred to as a “Load Loss Trip” and
can be used to detect a broken drive shaft or belt. In pumping
applications, this can be used as a “Loss of Prime” trip.
Under Current Trip
F037 = Under Current %
(F036 = 1)
Factory Setting = 40%
Range = 10 - 90%
Use to set the trip level for an under current condition for any phase.
Percentage is based on FLA (F001 setting).
F038 = Under Current Trip Delay
Factory Setting = 2 seconds
Range = 1 - 60 seconds
Provides a time delay to prevent nuisance trips from short-duration
transients. Using default settings, if the output current of any phase
drops below 40% of FLA for more than 2 seconds, the starter will trip.
F039 = Coast Down Lockout Timer (Back Spin Timer)
Factory Setting = 0 (Disabled)
Range = 0 - 1
When F039 = 1, this function provides a timer which prevents motor
restarts for the number of minutes specified in F040. This function is
Coast Down / Backspin Lockout useful in applications like pump motor backspin - (where you need to
prevent the pump motor from restarting if it is spinning backwards).
F040 = Coast Down Lockout Time
Factory Setting = 5 minutes
Range = 0 - 60 minutes
Sets a minimum amount of time that a starter must be off before a
restart can be completed. (Used in conjunction with F039).
F041 = Starts per Hour Lockout
Factory Setting = 0 (Disabled)
Range = 0 - 1
If F041=1, this feature will count the number of start commands within
a 1 hour period. If the setting of F042 (maximum starts per hour) is
exceeded, starting is prohibited until sufficient time has expired.
F042 = Maximum Starts per Hour
Factory Setting = 2
Range = 1 - 10
Consult the motor manufacturer for a “Starts-per-Hour” or “Starting Duty
Cycle” rating. Larger motors tend to have lower starts-per-hour ratings.
(Used in conjunction with F041).
Note: When using the Decel function (F025) or an electronic braking option, count
these cycles as additional “starts” when determining maximum starts-per-
hour.

5.5.9 System Settings

F060 = Parameter Lock / User Password
Factory Setting = 0 (disabled)
Range = 0 - 999
Provides users with the ability to prevent unauthorized operators from
making changes to the programmed functions. If you do not need to
take advantage of this feature, do not enter anything into this
function. The factory default is disabled, and no Password is necessary
to make changes to the program.
See Appendix 3 at the end of this manual for detailed instructions on
using and altering the Parameter Lock / User Password feature.
F061 = Emergency Clear / Reset
Factory Setting = 0 (disabled)
Range = 0 - 2
This Function serves two purposes. It can clear the memory values
used for lockouts and overload protection, and it can reset all functions
to the factory default settings.
When F061 = 0, the feature is disabled. This is a “One-Shot” feature,
so when another value is entered as shown below, this function
automatically returns to the default state.
When F061 = 1, the values stored in the Thermal Register and all of the
Lockout Timers will be cleared. This will allow an emergency restart
without having to wait for proper cool down time or lockout timers to
expire.
WARNING Clearing the Thermal Register to allow restarting without
proper cool-down time after an Overload Trip will risk motor
damage and fire. Use only where emergency restart is
necessary without regard to these potential hazards.
When F061 = 2, the values of all functions will be reset to the factory
default settings. Use this feature when settings conflict or have been
tampered with. This is also useful when you lose track of experimental
settings and wish to start over.

event. For instance, if Function F003 (overload protection) is set too low for the
size of the load, the code “oLA” will be displayed. Its corresponding number will
Over Load During Accel be entered into the fault history. In this case, the number 0010 will be available for
display in the window of function F075 (Fault History). The time the fault was
detected is available in Function F076. It is expressed as hh.mm. So if the “oLA”
fault occurred at 10:00 am, F076 would display 10.00. The date the fault occurred
Over Current During Accel
is available in Function F077. The date is expressed as mm.dd. So if the “oLA”
fault occurred on March 1, F077 would display 03.01.
If there are no fault conditions in history, the display in F075 would read 0000.

8.2 SCR Testing Procedure

Remove both line power and control power from the unit and lock out. Disconnect
any two motor load leads and any two line leads. Disconnect the SCR connections
to main control board J5, J6 and J7. Refer the Chapter 9 for the main control
board layout. Note the type of color coding of the wires connected to J5, J6 and
J7. TOSHIBA™ uses two possible configurations. Both configurations have 4
wires going to each plug. The first configuration consists of 4 wires color coded
black, yellow, grey and white. The second configuration consists of 4 wires color
coded red, white, red, white.

The testing procedure for SCRs is comprised of two separate tests. The first one
tests the anode to cathode integrity of the SCR by performing the following ohm
checks:

The second tests the gate to cathode integrity of the SCR. Place the leads of an
ohm meter into the receptacle that was unplugged from the main circuit board.
Ohm the pair of wires on one end of the plug. Then ohm the pair of wires on the
other end of the plug. The chart below indicates good versus bad readings.

Note: If any of the above readings are out of specifications, replace the faulty SCR.

Note: The best way to test an SCR is with an SCR Tester and look for leakage current
less than the manufacturer specified values.

8.3 Replacing SCR Devices

Two types of SCRs are used in the TD Series depending on the
horsepower/amperage rating of the unit. Isolated SCRs are used in
smaller units and “hockey puck” type SCRs are used in larger
units. (Refer to Chapter 9 for the main control board layout.)

8.3.1 Changing an Isolated SCR

• Remove both line and control power from unit, tag and lock out.

WARNING Failure to remove both line and control power before starting
this procedure may cause personal injury or death.

• Label the location of wires connected to the SCR.

• Remove the mounting screws, lugs and associated wiring from the
existing SCR.
• Make sure the surface to which the power module mounts is clean
and free from dirt, nicks and scratches.
• Apply thermal grease uniformly along the grooved area. Spread the
grease thinly (3 mil thick) to completely cover the base of the
power module and minimize air pockets. The grease must be free
of contamination.
• Replace the screws and tighten down firmly. All mounting screws
should be 44lb/in. Units with a maximum amperage rating of up to
48A, should use 26 lbs/in busbar and power lugs. Units with a
maximum amperage of 60A - 120A should use 44 lbs/in busbar
and power lugs.
• Reconnect all busbars, lugs and wires. Check to make sure the
gate and cathode are wired correctly. Use the following chart to
verify the wiring of J5, J6 and J7:
• After verifying that all wiring is correctly connected, test the SCR.

8.3.2 Changing a Hockey Puck Type SCR

• Remove both line and control power from unit, tag and lock out.

WARNING Failure to remove both line and control power before starting this
procedure may cause personal injury or death.

• TOSHIBA uses two types of clamps with gauges for reading the
amount of force on the device. The first type of force gauge uses a
spin washer. When the proper force is applied, the washer will be
free to spin. The second type of gauge uses a step indicator on the
end of the lever. Before proceeding, note the type of clamp used
and, if the clamp has a step indicator, document the position of the
indicator before removing the clamp to facilitate proper mounting of
the new SCR device.

• Label the location of the wires connected to the SCR.

• Remove any lugs, snubbers, printed circuit boards (refer to section

8.4) and associated wiring that may get in the way of reaching the
faulty SCR. Document the location and wiring of all parts before
removing them to facilitate the reinstallation of the devices later.

• Document the position of the indicator on the SCR clamp. Then remove
the top clamp holding the SCR stack together. Remove the top
heatsink. Use extreme caution when handling the heat sink so it does
not become dented or damaged.

• Remove the faulty SCR device, noting the direction in which the
SCR is oriented. The new SCR puck must be inserted in the same
direction.

• Make sure the SCR mounting surface, tools, and hands are clean
and free from dirt, nicks, and scratches. Do not sand or scrape SCR
mounting surface. If necessary, super fine Scotch Brite pads can be
used to clean the heatsink before installing the new SCR.

• Apply a thin (3 mil thick) layer of thermal grease uniformly along

both sides of the SCR. Spread the grease to cover the entire surface
of both sides of the SCR in a manner that minimizes air pockets.
The grease must be free of contamination.

• Locate the centering pin in the bottom and top of the heatsink and
center it in the SCR hole (making sure that the SCR is pointed in the
same direction as the SCR that was removed in step 6). Locate the
centering pin in the top heatsink and center it in the SCR hole.
If center pin is not placed correctly it will damage the SCR and
the heat sink.
Hand tighten the clamps evenly so that the same number of threads
appear at both ends of the U-clamp. Tighten the clamp 1/4 turn at a
time alternating sides of the U-clamp until the correct force is reached.
Check the gauge or spin washer every time the clamp nuts are tightened
1/4 turn to ensure that the SCR is not over torqued. The gauge reading
should be similar to the initial reading taken in step 2. If the clamp

TD - Series
- 39 -
TD Series Digital Solid State Soft Starter 48 - 1250A

uses the spin washer gauge, verify that the washer spins freely after
clamping. Once proper force is reached make sure that the SCR pucks
are securely held between the heatsinks and aligned evenly.

• Replace any lugs, MOVs, snubbers, power straps, printed circuit

boards and associated wiring that was removed in step 4. Use the
following chart to verify wiring of J5, J6 and J7:

• After verifying that all wiring is correctly connected, test the SCR
and then test the unit.

8.4 Replacing the Printed Circuit Board Assembly

The printed circuit board assembly is not intended to be field
repaired. If a board is faulty, the entire assembly should be
replaced using the following procedure:
(See Chapter 9 for the printed board assembly layout.)

• Remove three phase power and control power from the unit and
lock out.

• Remove plugs and tag plugs with connector numbers.

• Remove control wires from terminals and tag wires with terminal
numbers.

• Remove the mounting screws.

• Remove the old printed circuit board assembly.

• Mount the new printed circuit board assembly.

• Install the mounting screws.

• Install the control wires onto correct terminals per tag sequence.

• Install the plugs.

• Apply power to the unit and test.

Appendix 1 - Ramp Profile Details

Four Different Ramp Types
The TD Series offers four different types of starting ramp profiles. Simply select
the one that best matches your motor / load requirements.
Ramp Type
Setting
F010 Ramp 1 Ramp 2
Ramp 1 Voltage Ramp Voltage Ramp
Profile 2 Current Ramp Current Ramp
Selection 3 Voltage Ramp Current Ramp
4 Current Ramp Voltage Ramp

1. Voltage Ramping is the most reliable starting method, since at some point
the starter will reach an output voltage high enough to allow the motor to draw full
current and develop full torque. This method is useful for applications where the
load conditions change frequently and significantly enough to require different
levels of starting torque.
Examples where this is effective are:
• material handling conveyers
• positive displacement pumps
• drum mixers, etc.
Voltage is increased from a starting point (Initial Torque) to full voltage over an
adjustable period of time (Ramp Time).
To achieve Voltage Ramping, set the Ramp Profile (F010) to 0001 or 0003 (Voltage
Ramp), and the Maximum Current Limit setting (F014) to maximum (600%).
Since this is essentially Locked Rotor Current on most motors, there will be little
or no Current Limit effect on the Ramp profile.
2. Voltage Ramping with Current Limit works similarly to the above, except
adds an adjustable maximum current output. Voltage is increased gradually until
the Maximum Current Limit setting (F014) is reached, then held at this level until
the motor accelerates to full speed. This may be necessary in applications where
the electrical power is limited.
Examples would be:
• portable or emergency generator supplies
• utility power near the end of a transmission line
• utility starting power demand restrictions.
Using Current Limit will override the Ramp Time setting if necessary, so use this
feature when acceleration time is not critical.
To achieve Voltage Ramping with Current Limit, set the Ramp Profile (F010) to
0001 or 0003 (Voltage Ramp), and the Maximum Current Limit setting (F014) to
a desired lower setting, as determined by your applications requirements.
3. Current Ramping (Closed Loop Torque Ramping) is good for smooth linear
acceleration of output torque. Output voltage is constantly updated to provide
this linear current ramp, and therefore the available torque is maximized at any
given speed. The best use of this feature is for applications where rapid changes
in torque may result in load damage or equipment changes.
Examples would be:
• long overland conveyors where belt stretching may occur
• fans and mixers where blade warping is a problem
• material handling systems where stacked products may fall over or break.
TD - Series
- 43 -
TD Series Digital Solid State Soft Starter 48 - 1250A

This feature can be used with or without the Maximum Current Limit setting.
To achieve Current Ramping with the TD, set the Ramp Profile (F010) to 0002 or
0004 (Current Ramp), and the Maximum Current Limit setting (F014) to the
desired level.
4. Current Limit Only (Current Step) starting means using the Current Limit
feature exclusively without the benefit of soft starting by ramping the voltage or
current first. This will maximize the effective application of motor torque within the
limits of the motor. In this mode, Initial Voltage / Current and Ramp Time are set
to 0, so the output current jumps to the current limit setting immediately.
Examples of when to use this mode are:
• applications with a severely limited power supply
• when starting a difficult load such as a centrifuge or deep well pump
• when the motor capacity is barely adequate without stalling or overloading.
• It is a good choice when other starting modes fail.
Since ramp times are set to 0, this mode functions in either Voltage Ramp or
Current Ramp setting.
Ramp Parameter Description
Initial Torque (Initial Voltage or Initial Current). This function sets the initial
start point of either the Voltage Ramp or Current Ramp as programmed in F010.
Every load requires at least some amount of torque to start from a standstill. It is
not efficient to begin ramping the motor from zero every time, since between zero
and the (WK2) break-away torque level, no work is being performed. The initial
torque level should be set to provide just enough torque to make the motor shaft
begin to rotate, enabling the softest possible start and preventing torque shock
damage to the mechanical components. Setting this function too high will not
damage the starter, but may reduce or eliminate the soft start advantages. See
Chapter 5 for initial setup procedures.
Accel Ramp Time. This Function sets the maximum allowable time for ramping
the Initial voltage or current (torque) setting to either of the following:
1) Current limit setting when the motor is still accelerating, or
2) Full output voltage if the Current Limit is set to maximum.
Increasing the Ramp Time softens the start process by lowering the slope of
increase in voltage or current. This should be set to provide the softest possible
start without stalling unless you have determined that your application has other
considerations. Applications where this setting should be shorter include
Centrifugal Pumps, because pump problems may occur as a result of insufficient
torque during acceleration through the pump curve.
Note: Ramp Time is affected by the following conditions:
1. Current Limit will extend the Ramp Time if the motor does not reach full
speed while in current limit mode.
2. The Anti-Oscillation Circuit will shorten the Ramp Time if the motor reaches
full speed before end of ramp.
Current Limit. This Function sets the maximum motor current that the starter
allows during Ramping. It is active in both the Voltage Ramp and Current Ramp
modes. As the motor begins to ramp, this feature will set a ceiling at which the
current draw will be held. Current Limit will remain in effect until one of the following
two events occur:
1) The motor reaches full speed as detected by the At-Speed detection circuit.

TD - Series
- 44 -
TD Series Digital Solid State Soft Starter 48 - 1250A

2) The Overload Protection trips on Motor Thermal Overload (see Ch.3).

Once the motor has reached full speed, the Current Limit feature becomes inactive.
In the Voltage Ramp Profile, the Voltage output is increased until the Current
Limit is reached. The Ramp Time is the maximum time it will take for the voltage
to increase until the Current Limit setting takes over. Under some load conditions,
Current Limit may be reached before the Ramp Time has expired.
In the Current Ramp Profile, output voltage varies to provide a linear increase in
current up to the Current Limit setting, and Ramp Time is the time that it will take
to get there. A closed loop feedback of motor current allows continuous updating
of the output to maintain this ramp profile.
Because most AC induction motors will not start below 200% current, the current
limit set point is adjustable down to only 200%.. Use this feature to prevent
voltage drop in your electrical supply, portable / emergency generator stalling, or
to satisfy utility restrictions on starting power.
CAUTION While the TD is in Start mode there is no maximum Current Limit time.
Excessive start time may however lead to motor stalling, causing an
Overload Trip. If this happens, try raising the Current Limit setting to
accommodate your load conditions. If the Current Limit setting cannot
be increased, try using Current Limit without ramping features (“Current
Limit Only” as described previously).

Appendix 2: Decel Mode Application Considerations

Deceleration (Soft Stop) is a unique feature of Solid State Soft Starters such as
the TD. It provides a slow decrease in the output voltage, accomplishing a
Coasting Stop gentle decrease in motor torque during the stopping mode. This is the
(using Electro-Mech. starter) OPPOSITE OF BRAKING in that it will take longer to come to a stop than if
the starter were just tuned off. The primary use of this function is with centrifugal

PUMP FLOW in pump applications is often referred to as Pump Control.
In a pump system, liquid is being pushed uphill. The force exerted by gravity
Check Valve on the column of liquid as it goes up hill is called the “Head Pressure” in the
PUMP
OFF Slams system. The pump is sized to provide enough Output Pressure to overcome
BACK FLOW
the Head Pressure and move the fluid up the pipe. When the pump is turned
off, the Output Pressure rapidly drops to zero and the Head Pressure takes
over to send the fluid back down the hill. A “Check Valve” is used somewhere

one direction. The kinetic energy in that moving fluid is suddenly trapped when
SHOCK WAVE the valve slams closed. Since fluids can’t compress, that energy is transformed
into a “Shock Wave” that travels through the piping system looking for an
outlet in which to dissipate. The sound of that shock wave is referred to as
Pump Control Soft Stop with RVSS
“Water Hammer”. The energy in that shock wave can be extremely damaging

Another common application is on material handling conveyors as a means to
prevent sudden stops that may cause products to fall over or to bump into one

Appendix 3: Parameter Lock / User Password Instructions

F060 = Parameter Lock / User Password Provides users with the ability to prevent unauthorized operators from making
Factory Setting = 0 (disabled) changes to the programmed functions. If you do not need to take advantage
Range = 0 - 999 of this feature, do not enter anything into this function. The factory default
is disabled, and no Password is necessary to make changes to the program.
When any value other than 0 is entered into this Function, the Parameter Lock
is enabled and that number becomes the User Password. From that point
forward, it will be necessary to enter the User Password in this Function prior
to making changes in any programmed function, including this one. When the
Parameter Lock has been enabled, attempts to alter the program will result in
the display reading Err whenever the READ / ENTER key is pressed.
To be able to alter the program after the Parameter Lock has been enabled, go
to Function (F060) and enter the correct user Password. When the READ /
ENTER button is pressed, the display will read PASS, indicating that the User
Password is correct and the system is unlocked. You will have 5 minutes in
which to make a change in the program. This 5 minute window resets whenever
any key is pressed, so it floats to give you 5 minutes after the last entry. After
5 minutes of no keypad activity, the Parameter Lock is reinstated with the
current user Password. Subsequent changes will require re-entering the User
Password.
To change the User Password or to disable the Parameter Lock function,
enter the programmed User Password first, then set Function F060 to 0 (F060
= 0), disabling the Parameter Lock. If you do not re-enter the Password or
enter a new user password, the Parameter Lock feature will remain disabled.
If you enter a different number into this Function, the new number becomes
your new User Password.
The User Password will not be displayed after being entered or at any other
time. The number displayed after the READ / ENTER key is initially pressed
is for reference only. Caution: DO NOT LOSE YOUR PASSWORD. If the password has
been lost or forgotten, contact TOSHIBA for assistance in retrieving it with
authorization.
