"Wiring and EMC Considerations" on page 9. In general:
• Follow local codes for cable size.
• Keep these four classes of wiring separated: input power wiring, motor wiring,
control/communications wiring, and braking unit wiring.
• Refer to "Motor Cable" on page 10 for the motor cable length limit imposed by
possible EMC requirements (CE or C-Tick).
• Refer to the specifications/recommendations in:
"Input Power (Mains) Cables and Fuses" on page 129,
"Cable Terminals" on page 129,
"Input Power (Mains) Connection" on page 130, and
"Motor Connection" on page 130.

EMC Instructions (Europe, Australia, and New Zealand)

This section describes conformance with EMC requirements (in Europe, Australia,
and New Zealand). For installations in the Unites States and other locations without
special EMC requirements, skip to "Control Cables" on page 13.

CE Marking (pending as of publication date)

A CE mark is attached to the ACS550 AC drive to verify that the drive follows the
provisions of the European Low Voltage and EMC Directives (Directive 73/23/EEC,
as amended by 93/68/EEC and Directive 89/336/EEC, as amended by 93/68/EEC).
The EMC Directive defines the requirements for immunity and emissions of electrical
equipment used in European Economic Area. The EMC product standard EN 61800-
3 covers the requirements stated for drives, such as the ACS550. ACS550 AC drives
comply with the requirements stated in EN 61800-3 for Second Environment and
First Environment, restricted distribution.
Product standard EN 61800-3 (Adjustable speed electrical power drive systems -
Part 3: EMC product standard including specific test methods) defines First
Environment as environment that includes domestic premises. It also includes
establishments directly connected without intermediate transformers to a low voltage
power supply network which supplies buildings used for domestic purposes.

Installation
10 ACS550 User’s Manual

Second Environment includes establishments other than those directly connected

to a low voltage power supply network which supplies buildings used for domestic
purposes.

C-Tick Marking (pending as of publication date)

A C-tick mark is attached to the ACS550 AC drive to verify that the drive follows the
provisions of the Australian Statuary Rules No 294, 1996, Radio communication
(Compliance Labelling - Incidental Emissions) Notice and the Radio communication
Act, 1989, and the Radio communication Regulations, 1993, of New Zealand.
The statutory rules define the essential requirements for emissions of electrical
equipment used in Australia and New Zealand. The standard AS/NZS 2064, 1997,
Limits and methods of measurement of electronic disturbance characteristics of
industrial, scientific and medical (ISM) radio frequency equipment, covers the
detailed requirements for three-phase drives, such as the ACS550 drive.
ACS550 drives comply with the AS/NZS 2064, 1997, limits for class A equipment.
Class A equipment is suitable for use in all establishments other than domestic and
those directly connected to a low voltage network which supplies buildings used for
domestic purposes. The compliance is valid with the following provisions:
• The motor and control cables are chosen as specified in this manual.
• The installation rules of this manual are followed.

Cabling Instructions
Keep individual un-screened wires between the cable clamps and the screw
terminals as short as possible. Route control cables away from power cables.

Input Power (Mains) Cable

A four conductor cable (three phases and ground/protective earth) is recommended
for the input power cabling. Shielding is not necessary. Dimension the cables and
fuses in accordance with the input current. Always pay attention to local codes when
sizing the cables and fuses.
The input power connectors are at the bottom of the drive. Input power cable routing
must be done so that the distance from the sides of the drive is at least 20 cm (8 in)
to avoid excessive radiation to the input power cable. In the case of shielded cable,
twist the cable screen wires together into a bundle not longer than five times its width
and connect to the PE terminal of the drive. (Or PE terminal of input filter, if present.)
Line current harmonics
The ACS550 is professional equipment to be used in trades, professions, or
industries, and is not intended for sale to the general public. The current harmonic
levels under rated load conditions are available on request.

Motor Cable
Minimum Requirement (CE & C-Tick)
The motor cable must be a symmetrical three conductor cable with a concentric PE
conductor or a four conductor cable with a concentric shield, however, a symmetrical

Installation
ACS550 User’s Manual 11

constructed PE conductor is always recommended. The following figure shows the

minimum requirement for the motor cable screen (for example, MCMK, NK Cables).

Effective Motor Cable Screens

The general rule for cable screen effectiveness is: the better and tighter the screen
of the cable, the lower the radiated emission level. The following figure shows an
example of an effective construction (for example Ölflex-Servo-FD 780 CP,
Lappkabel or MCCMK, NK Cables).

Clamp the cable shield into the gland plate at the drive end and twist the cable
screen wires together into a bundle not longer than five times its width and connect it
to the terminal marked (at the bottom right-hand corner of the drive), if you are
using cable without a separate PE conductor.

Installation
12 ACS550 User’s Manual

At the motor end the motor cable screen must be earthed 360 degrees with an EMC
cable gland or the screen wires must be twisted together into a bundle not longer
than five times its width and connected to the PE terminal of the motor.
EN61800-3 and AS/NZS 2064, 1997, Class A Compliant Motor Cables
To comply with EN61800-3, First and Second Environment, Restricted Distribution,
and AS/NZS 2064, 1997, Class A requirements, motor cables:
• less than or equal to 30 m (100 ft) do not require an RFI filter.

Installation
ACS550 User’s Manual 13

Control Cables
General Recommendations
Use shielded cables, temperature rated at 60 °C (140 °F) or above:
• Control cables must be multi-core cables with a braided copper wire screen.

Double Shielded Single Shielded

Example: JAMAK by Draka NK Cables Example: NOMAK by Draka NK Cables

• The screen must be twisted together into a bundle not longer than five times its
width and connected to terminal X1-1 (for digital and analog I/O cables) or to
either X1-28 or X1-32 (for RS485 cables).
Route control cables to minimize radiation to the cable:
• Route as far away as possible from the input power and motor cables (at least
20 cm (8 in)).
• Where control cables must cross power cables make sure they are at an angle as
near 90° as possible.
• Stay at least 20 cm (8 in) from the sides of the drive.
Use care in mixing signal types on the same cable:
• Do not mix analog and digital input signals on the same cable.
• Run relay-controlled signals as twisted pairs (especially if voltage > 48 V). Relay-
controlled signals using less than 48 V can be run in the same cables as digital
input signals.

Note! Never mix 24 VDC and 115/230 VAC signals in the same cable.

Analog Cables
Recommendations for analog signal runs:
• Use double shielded, twisted pair cable
• Use one individually shielded pair for each signal.
• Do not use a common return for different analog signals.
Digital Cables
Recommendations for digital signal runs:
• A double shielded cable is the best alternative, but single shielded twisted multi-
pair cable is also usable.
Control Panel Cable
If the control panel is connected to the drive with a cable, use only Category 5 Patch
ethernet cable.

Power Connections

Warning! Ensure the motor is compatible for use with the ACS550. The
ACS550 must be installed by a competent person in accordance with the
considerations defined in "Preparing for Installation" on page 7. If in doubt,
contact your local ABB sales or service office.

• Refer to the following table to complete the power connections. If appropriate,

also perform the instructions for the braking and floating networks.
Terminal Frame Size Description Note
U1, V1, W1* R1…R6 3-phase power supply input "Input Power (Mains) Connection" on
page 130.
PE R1…R6 Protective Ground Follow local rules for cable size.
U2, V2, W2 R1…R6 Power output to motor "Motor Connection" on page 130.

* For single phase supply voltage connect power at U1 and W1.

Optional Braking
• For drives with the braking accessory, install one of the following, depending on
the drive’s frame size:
Frame Size Terminal Description Braking Accessory
R1, R2 BRK+, BRK- Braking resistor Braking resistor.
R3, R4, R5, R6 UDC+, UDC- DC bus • Braking unit or
• Chopper and resistor

Floating Networks
For floating networks (also known as IT, ungrounded, or high impedance networks):
• Disconnect the internal RFI filter by removing both the EM1 and EM3 screws
(frame sizes R1…R4, see 17), or F1 and F2 screws (frame sizes R5…R6, see
16).
• Where EMC requirements exist, check for excessive emission propagated to
neighboring low voltage networks. In some cases, the natural suppression in
transformers and cables is sufficient. If in doubt, use a supply transformer with
static screening between the primary and secondary windings.
• Do NOT install an external filter, such as one of the kits listed in the filter table on
12. Using an RFI filter grounds the input power through the filter capacitors, which
could be dangerous and could damage the unit.

Control Connections
To complete the control connections, use:
• Following tables

Warning! Because the low end of the reference range
commands full reverse operation, do not use 0 V as the lower end of the reference range. Doing so means
that if the control signal is lost (which is a 0 V input) the result is full reverse operation. Instead, use the
following set-up so that loss of the analog input triggers a fault, stopping the drive:
• Set parameter 1301 MINIMUM AI1 (1304 MINIMUM AI2) at 20% (2 V or 4 mA).
• Set parameter 3021 AI1 FAULT LIMIT to a value 5% or higher.

• If the DC bus voltage drops due to loss of input power, the undervoltage controller decreases the motor speed in
order to keep the DC bus voltage above the lower limit.
• When the motor speed decreases, the inertia of the load causes regeneration back into the drive, keeping the DC
bus charged, and preventing an undervoltage trip.
• The DC undervoltage controller increases power loss ride-through on systems with a high inertia, such as a
centrifuge or a fan.
0 = DISABLE – Disables controller.
1 = ENABLE – Enables controller without a maximum time limit for operation.

using DC current. The normal control is released exactly after the magnetizing time. This selection guarantees
the highest possible break-away torque.
• SCALAR control mode: Magnetizes the motor within the time determined by the parameter 2103 DC MAGN TIME
using DC current. The normal control is released exactly after the magnetizing time.
3 = SCALAR FLYSTART – Selects the flying start mode.
• VECTOR control mode: Not applicable.
• SCALAR control mode: The drive will automatically selects the correct output frequency to start a rotating motor.
Useful if the motor is already rotating and the drive will start smoothly at the current frequency.
4 = TORQ BOOST – Selects the automatic torque boost mode (SCALAR control mode only).
• May be necessary in drives with high starting torque.
• Torque boost is only applied at start, ending when output frequency exceeds 20 Hz or when output frequency is
equal to reference.

Warning! IEC 60664 requires double or reinforced insulation between live parts
and the surface of accessible parts of electrical equipment which are either
non-conductive or conductive but not connected to the protective earth.
To fulfil this requirement, connect a thermistor (and other similar components)
to the drive’s control terminals using any of these alternatives:
• Separate the thermistor from live parts of the motor with double reinforced
insulation.
• Protect all circuits connected to the drive’s digital and analog inputs.
Protect against contact, and insulate from other low voltage circuits with
basic insulation (rated for the same voltage level as the drive’s main
circuit).
• Use an external thermistor relay. The relay insulation must be rated for the
same voltage level as the drive’s main circuit.

For other faults, or for anticipating motor overheating using a model, see Group 30:

Group 40: Process PID Set 1

This group defines a process PID control operation mode for the drive. In PID control
mode, the drive compares a reference signal (setpoint) to an actual signal
(feedback), and automatically adjusts the speed of the drive to match the two
signals. The difference between the two signals is the error value.
Three groups of parameters define PID control:
• Group 40 Process PID Set 1 defines process PID Set 1. Normally, this parameter
set is used.
• Group 41 Process PID Set 2 defines process PID Set 2.
Both Group 40 and 41 have the same parameters, except for the parameter used

Group 81: PFC Control

This group defines a Pump-Fan Control (PFC) mode of operation. The major
features of PFC control are:
• The ACS550 controls the motor of pump no. 1, varying the motor speed to control
the pump capacity. This motor is the speed regulated motor.
• Direct line connections power the motor of pump no. 2 and pump no.3, etc. The
ACS550 switches pump no. 2 (and then pump no. 3, etc.) on and off as needed.
These motors are auxiliary motors.
• The ACS550 PID control uses two signals: a process reference and an actual
value feedback. The PID controller adjusts the speed (frequency) of the first
pump such that the actual value follows the process reference.
• When demand (defined by the process reference) exceeds the first motor’s
capacity (user defined as a frequency limit), the PFC control automatically starts
an auxiliary pump. The PFC also reduces the speed of the first pump to account
for the auxiliary pump’s addition to total output. Then, as before, the PID controller
adjusts the speed (frequency) of the first pump such that the actual value follows
the process reference. If demand continues to increase, PFC adds additional
auxiliary pumps, using the same process.
• When demand drops, such that the first pump speed falls below a minimum limit
(user defined by a frequency limit), the PFC control automatically stops an
auxiliary pump. The PFC also increases the speed of the first pump to account for
the auxiliary pump’s missing output.
• An Interlock function (when enabled) identifies off-line (out of service) motors, and
the PFC control skips to the next available motor in the sequence.
• An Autochange function (when enabled and with the appropriate switchgear)
equalizes duty time between the pump motors. Autochange periodically
increments the position of each motor in the rotation – the speed regulated motor
becomes the last auxiliary motor, the first auxiliary motor becomes the speed
regulated motor, etc.
Code Description
8103 REFERENCE STEP 1
Sets a percentage value that is added to the process reference.
• Applies only when at least one auxiliary (constant speed) motor is running.
• Default value is 0%.
Example: An ACS550 operates three parallel pumps that maintain water pressure in a pipe.
• 4011 INTERNAL SETPNT sets a constant pressure reference that controls the pressure in the pipe.
• The speed regulated pump operates alone at low water consumption levels.
• As water consumption increases, first one constant speed pump operates, then, the second.
• As flow increases, the pressure at the output end of the pipe drops relative to the pressure measured at the input
end. As auxiliary motors step in to increase the flow, the adjustments below correct the reference to more closely
match the output pressure.
• When the first auxiliary pump operates, increase the reference with parameter 8103 REFERENCE STEP 1.
• When both auxiliary pumps operate, increase the reference with parameter 8103 reference step 1 + parameter
8104 reference step 2.
• When three auxiliary pumps operate, increase the reference with parameter 8103 REFERENCE STEP 1 + parameter
8104 REFERENCE STEP 2 + parameter 8105 REFERENCE STEP 3.

Code Description
8117 NR OF AUX MOT
Sets the number of auxiliary motors.
• Each auxiliary motor requires a relay output, which the drive uses to send start/stop signals.
• The Autochange function, if used, requires an additional relay output for the speed regulated motor.
• The following describes the set-up of the required relay outputs.
Relay Outputs
As noted above, each auxiliary motor requires a relay output, which the drive uses to send start/stop signals. The
following describes how the drive keeps track of motors and relays.
• The ACS550 provides relay outputs RO1…RO3.
• An external digital output module can be added to provide relay outputs RO4…RO6.
• Parameters 1401…1403 and 1410…1412 define, respectively, how relays RO1…RO6 are used – the parameter
value 31 PFC defines the relay as used for PFC.
• The ACS550 assigns auxiliary motors to relays in ascending order. If the Autochange function is disabled, the first
auxiliary motor is the one connected to the first relay with a parameter setting = 31 PFC, and so on. If the
Autochange function is used, the assignments rotate. Initially, the speed regulated motor is the one connected to
the first relay with a parameter setting = 31 PFC, the first auxiliary motor is the one connected to the second relay
with a parameter setting = 31 PFC, and so on.

8118 AUTOCHNG INTERV

Controls operation of the Autochange function and sets the interval between changes.
• The Autochange time interval only applies to the time when the speed regulated motor is running.
• See parameter 8119 AUTOCHNG LEVEL for an overview of the Autochange function.
• The drive always coasts to a stop when autochange is performed.
• Autochange enabled requires parameter 8120 INTERLOCKS = value > 0.
0.0 = NOT SEL – Disables the Autochange function.
0.1…336 = The operating time interval (the time when the start signal is on) between automatic motor changes.
Warning! When enabled, the Autochange function requires the interlocks (8120 interlocks = value > 0)
enabled. During autochange the interlocks interrupt the drive’s power output, preventing damage to the
contacts.

Code Description
8119 AUTOCHNG LEVEL
Sets an upper limit, as a percent of output capacity, for the autochange logic. When the output from the PID/PFC
control block exceeds this limit, autochange is prevented. For example, use this parameter to deny autochange when
the Pump-Fan system is operating near maximum capacity.
Autochange Overview
The purpose of the autochange operation is to equalize duty time between multiple motors used in a system. At each
autochange operation:
• A different motor takes a turn connected to the ACS550 output – the speed regulated motor.
• The starting order of the other motors rotates.
The Autochange function requires:
• External switchgear for changing the dive’s output power connections.
• Parameter 8120 INTERLOCKS = value > 0.
Autochange is performed when:
• The running time since the previous autochange reaches the time set by 8118 AUTOCHNG INTERV
• The PFC input is below the level set by this parameter, 8119 AUTOCHNG LEVEL.
Note! The ACS550 always coasts to stop when autochange is performed.
In an autochange, the Autochange function does all of the PID Output
following (see figure): A
4PFC
• Initiates a change when the running time, since the last 100%
autochange, reaches 8118 AUTOCHNG INTERV, and PFC 2PFC
input is below limit 8119 AUTOCHNG LEVEL.
• Stops the speed regulated motor. P 8119
3PFC
• Switches off the contactor of the speed regulated motor. 3PFC
• Increments the starting order counter, to change the 4PFC

• Identifies the next motor in line to be the speed regulated
motor. 1PFC t
• Switches off the above motor’s contactor, if the motor was P 8122
running. Any other running motors are not interrupted.
• Switches on the contactor of the new speed regulated P 8118 P 8118
motor. The autochange switchgear connects this motor to B
the ACS550 power output. A = Area above 8119 AUTOCHNG LEVEL –
• Delays motor start for the time 8122 PFC START DELAy. autochange not allowed.
• Starts the speed regulated motor. B = Autochange occurs.
• Identifies the next constant speed motor in the rotation. 1PFC, etc. = PID output associated with each motor.
• Switches the above motor on, but only if the new speed
regulated motor had been running (as a constant speed
motor) – This step keeps an equal number of motors running before and after autochange.
• Continues with normal PFC operation.
Starting Order Counter Output
The operation of the starting-order counter: frequency 2 aux
No aux 1 aux
• The relay output parameter definitions (1401…1403 and motors motor motors
1410…1412)) establish the initial motor sequence. (The lowest fMAX
parameter number with a value 31 (PFC) identifies the relay
connected to 1PFC, the first motor, and so on.)
• Initially, 1PFC = speed regulated motor, 2PFC = 1st auxiliary
motor, etc.
• The first autochange shifts the sequence to: 2PFC = speed
regulated motor, 3PFC = 1st auxiliary motor, …, 1PFC = last
auxiliary motor. Area
• The next autochange shifts the sequence again, and so on. Autochange
• If the autochange cannot start a needed motor because all is Allowed PID output
inactive motors are interlocked, the drive displays an alarm

(INTERLOCK).
• When ACS550 power supply is switched off, the counter
preserves the current Autochange rotation positions in permanent memory. When power is restored, the
Autochange rotation starts at the position stored in memory.
• If the PFC relay configuration is changed (or if the PFC enable value is changed), the rotation is reset. (See the first
bullet above.)

8120 INTERLOCKS
Defines operation of the Interlock function. When the Interlock function is enabled:
• An interlock is active when its command signal is absent.
• An interlock is inactive when its command signal is present.
• The ACS550 will not start if a start command occurs when the speed regulated motor’s interlock is active – the
control panel displays an alarm (INTERLOCK).
Wire each Interlock circuit as follows:
• Wire a contact of the motor’s On/Off switch to the Interlock circuit – the drive’s PFC logic can then recognize that
the motor is switched off, and start the next available motor.
• Wire a contact of the motor thermal relay (or other protective device in the motor circuit) to the Interlock input – the
drive’s PFC logic can then recognize that a motor fault is activated and stop the motor.

8121 REG BYPASS CTRL
Selects Regulator by-pass control. When enabled, Regulator by-pass control provides a simple control mechanism
without a PID regulator.
• Use Regulator by-pass control only in special
fOUT
applications.
0 = NO – Disables Regulator by-pass control. The drive fMAX
uses the normal PFC reference: 1106 REF2 SELECT.
1 = YES – Enables Regulator by-pass control.
• The process PID regulator is bypassed.
Actual value of PID is used as the PFC reference P 8110
(input). Normally EXT REF2 is used as the PFC P 8109
reference.
• The drive uses the feedback signal defined by 4014
FBK SEL (or 4114) for the PFC frequency reference.

8122 PFC START DELAY

Sets the start delay for speed regulated motors in the system. Using the delay, the drive works as follows:
• Switches on the contactor of the speed regulated motor – connecting the motor to the ACS550 power output.
• Delays motor start for the time 8122 PFC START DELAY.
• Starts the speed regulated motor.
• Starts auxiliary motors. See parameter 8115 for delay.
Warning! Motors equipped with star-delta starters require a PFC Start Delay.
• After the ACS550 relay output switches a motor On, the star-delta starter must switch to the star-connection and
then back to the delta-connection before the drive applies power.
• So, the PFC Start Delay must be longer than the time setting of the star-delta starter.
8123 PFC ENABLE
Selects PFC control. When enabled, PFC control:
• Switches in, or out, auxiliary constant speed motors as output demand increases or decreases. Parameters 8109
START FREQ 1 to 8114 LOW FREQ 3 define the switch points in terms of the drive output frequency.
• Adjusts the speed regulated motor output down, as auxiliary motors are added, and adjusts the speed regulated
motor output up, as auxiliary motors are taken off line.
• Provides Interlock functions, if enabled.
• Requires 9904 MOTOR CTRL MODE = 3 SCALAR.
0 = NOT SEL – Disables PFC control.
1 = ACTIVE – Enables PFC control.

Diagnostics

Warning! Do not attempt any measurement, parts replacement or other service

procedure not described in this manual. Such action will void the warranty,
may endanger correct operation, and increase downtime and expense.

Warning! All electrical installation and maintenance work described in this

chapter should only be undertaken by qualified service personnel. The Safety
instructions on the first pages of this manual must be followed.

Diagnostic Displays
When a drive detects an error, it provides a diagnostic display. The display appears
using:
• The green and red LED on the body of the drive
• The status LED on the control panel (if a control panel is attached to the drive)
• The control panel display (if a control panel is attached to the drive)
The form of the display depends on the severity of the error.

Red – Faults
The drive signals that it has detected a severe error, or fault, by:
• Enabling the red LED on the drive (LED is either steady on or blinking).
• Overriding the control panel display with the display of a fault code.
• Stopping the motor (if it was on).
The fault code on the control panel display is temporary. Pressing any of the
following buttons removes the fault message: MENU, ENTER, UP button, or DOWN
button. The message reappears after a few seconds if the control panel is not
touched and the fault is still active.

Correcting Faults
The recommended corrective action for faults is:
• Use the "Fault Listing" table below to find and address the root cause of the
problem.
• Reset the drive. See "Fault Resetting" on page 123.

Maintenance

Warning! Read "Safety" on page 3 before performing any maintenance on the

equipment. Ignoring the safety instructions can cause injury or death.

Maintenance Intervals
If installed in an appropriate environment, the drive requires very little maintenance.
This table lists the routine maintenance intervals recommended by ABB.
Maintenance Interval Instruction
Heatsink temperature check Depends on the dustiness of the See "Heatsink" on page 124.
and cleaning environment (every 6…12
months)
Main cooling fan replacement Every five years See "Main Fan" on page 124.
Capacitor change Every ten years See "Capacitors" on page 125.
(Frame size R5 and R6)

Heatsink
The heatsink fins accumulate dust from the cooling air. Since a dusty heatsink is less
efficient at cooling the drive, overtemperature faults become more likely. In a
“normal” environment (not dusty, not clean) check the heatsink annually, in a dusty
environment check more often.
Clean the heatsink as follows (when necessary):
1. Remove power from drive.
2. Remove the cooling fan (see section "Main Fan" on page 124).
3. Blow clean compressed air (not humid) from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust.

Note: If there is a risk of the dust entering adjoining equipment, perform the cleaning
in another room.

4. Replace the cooling fan.

5. Restore power.

Main Fan
The drive’s main cooling fan has a life span of about 60,000 operating hours at
maximum rated operating temperature and drive load. The expected life span
doubles for each 10 °C (18 °F) drop in the fan temperature (fan temperature is a
function of ambient temperatures and drive loads).

Maintenance
ACS550 User’s Manual 125

Fan failure can be predicted by the increasing noise from fan bearings and the
gradual rise in the heatsink temperature in spite of heatsink cleaning. If the drive is
operated in a critical part of a process, fan replacement is recommended once these
symptoms start appearing. Replacement fans are available from ABB. Do not use
other than ABB specified spare parts.

Capacitors
The drive intermediate circuit employs several Bottom View (R6) 3
electrolytic capacitors. Their life span is from
35,000…90,000 hours depending on drive
loading and ambient temperature. Capacitor
life can be prolonged by lowering the ambient 2
temperature.
It is not possible to predict a capacitor failure.
X0022
Capacitor failure is usually followed by a input
power fuse failure or a fault trip. Contact ABB
if capacitor failure is suspected. Replacements for frame size R5 and R6 are
available from ABB. Do not use other than ABB specified spare parts.

Symbols
Typical ratings:
Normal use (10% overload capability)
I2N continuous rms current. 10% overload is allowed for one minute.
PN typical motor power. The power ratings apply to most IEC 34, or NEMA 4-pole motors at the
nominal voltage, 400 V or 460 V.
Heavy-duty use (50% overload capability)
I2hd continuous rms current. 50% overload is allowed for one minute.
Phd typical motor power. The power ratings apply to most IEC 34, or NEMA 4-pole motors at the
nominal voltage, 400 V or 460 V.

Sizing
The current ratings are the same regardless of the supply voltage within one voltage
range. To achieve the rated motor power given in the table, the rated current of the
drive must be higher than or equal to the rated motor current.
Note 1: The maximum allowed motor shaft power is limited to 1.5 · Phd. If the limit is
exceeded, motor torque and current are automatically restricted. The function
protects the input bridge of the drive against overload.
Note 2: The ratings apply in ambient temperature of 40 °C (104 °F).

Derating
The load capacity (current and power) decreases if the installation site altitude
exceeds 1000 meters (3300 ft), or if the ambient temperature exceeds 40 °C
(104 °F) or if 8 kHz switching frequency (parameter 2606) is used.
Temperature Derating
In the temperature range +40 °C…50 °C (+104 °F…122 °F) the rated output current
is decreased 1% for every 1 °C (1.8 °F) above +40 °C (+104 °F). The output current
is calculated by multiplying the current given in the rating table by the derating factor.
Example If the ambient temperature is 50 °C (+122 °F) the derating factor is
100% - 1%/°C x 10 °C = 90% or 0.90.
The output current is then 0.90 x I2N or 0.90 x I2hd.
Altitude Derating
In altitudes from 1000…4000 m (3300…13,200 ft) above sea level, the derating is 1%
for every 100 m (330 ft). If the installation site is higher than 2000 m (6600 ft) above
sea level, please contact your local ABB distributor or office for further information.
Single Phase Supply Derating
If the input supply is single phase, rather than 3-phase, the derating is 50%.
Switching Frequency Derating
If the 8 kHz switching frequency (parameter 2606) is used, derate PN/Phd and I2N/
I2hd to 80%.

ladder side by side, ambient temperature 30 °C (86 °F), EN 60204-1 and IEC 364-5-523). For other
conditions, dimension the cables according to local safety regulations, appropriate input voltage and
the load current of the drive. In any case, the cable must be between the minimum limit defined in this
table and the maximum limit defined by the terminal size (see "Cable Terminals" on page 129).

motor protection feature that complies with the requirements of UL 508C. When this
feature is selected and properly adjusted, additional overload protection is not
required unless more than one motor is connected to the drive or unless additional
protection is required by applicable safety regulations. See parameters 3005 (MOT
THERM PROT) and 3006 (MOT THERM RATE).

The drives are to be used in a controlled environment. See section "Ambient
