following safety guidelines before connecting power to the AC motor drives. Keep this
operating manual handy and distribute to all users for reference.

! WARNING

! Always read this manual thoroughly before using VFD-S series AC Motor Drives.
! DANGER! AC input power must be disconnected before any maintenance. Do not
connect or disconnect wires and connectors while power is applied to the circuit.
Maintenance must be performed by qualified technicians.
! CAUTION! There are highly sensitive MOS components on the printed circuit boards.
These components are especially sensitive to static electricity. To avoid damage to these
components, do not touch these components or the circuit boards with metal objects or
your bare hands.
! DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages
even if the power has been turned off. To avoid personal injury, do not remove the cover
of the AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note
that there are live components exposed within the AC drive. Do not touch these live parts.
! CAUTION! Ground the VFD-S using the ground terminal. The grounding method must
comply with the laws of the country where the AC drive is to be installed. Refer to Basic
Wiring Diagram (CH 3-1).
! DANGER! The AC drive may be destroyed beyond repair if incorrect cables are
connected to the input/output terminals. Never connect the AC drive output terminals U,
V, and W directly to the AC main circuit power supply.

CAUTION! Heat sink may heat up over 70 (158 ), during the operation. Do not touch
the heat sink.

 Chapter 3 Wiring

Note: Use twisted-shielded, twisted-pair or shielded-lead wires for the control signal wiring. It
is recommended to run all signal wiring in a separate steel conduit. The shield wire
should only be connected at the drive. Do not connect shield wire on both ends.

CH 3-5 Wiring Notes:

1. ! CAUTION: Do not connect the AC input to any of the U, V, W terminals, as it will

damage the AC drive.

2. ! WARNING: Ensure all screws are tightened to the proper torque rating.

3. During installation, follow all local electrical, construction, and safety codes for the country
the drive is to be installed in.

4. Ensure that the appropriate protective devices (circuit breaker or fuses) are connected
between the power supply and AC drive.

5. Make sure that the leads are connected correctly and the AC drive is properly grounded.
(Ground resistance should not exceed 100 . For 460V-class AC drive, the ground
resistance should not exceed 10 .)

6. Use ground leads that comply with AWG/MCM standards and keep them as short as
possible.

7. Multiple VFD-S units can be installed in one location. All the units should be grounded
directly to a common ground terminal. The VFD-S ground terminals may also be connected
in parallel, as shown in the figure below. Ensure there are no ground loops.

Forward
running

8. When the AC drive output terminals U, V, and W are connected to the motor terminals U, V,
and W, respectively, the motor will rotate counterclockwise (as viewed from the shaft ends
of the motor) when a forward operation command is received. To reverse the direction of
motor rotation, switch over any of the two motor leads.

9. Make sure that the power source is capable of supplying the correct voltage and required
current to the AC drive.

© 1999 DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED

14
 Chapter 3 Wiring

10. Do not attach or remove wiring when power is applied to the AC drive.

11. Do not monitor the signals on the circuit board while the AC drive is in operation.

12. For the single-phase applications, the AC input line can be connected to any two of the
three input terminals R, S, T. Note: This drive is not intended for the use with single-
phase motors.

13. Route the wires of Power Terminals and Control Terminals separately, or 90°angle to each
other.

14. If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as
possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

15. If the AC drive is installed in the place where load reactor is needed, install the filter close
to U.V.W. side of AC drive. Do not use a Capacitor or L-C Filter (Inductance-Capacitance)
or R-C Filter (Resistance-Capacitance).

16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with not less than
200mA, with not less than 0.1-second detection to avoid nuisance tripping

CH 3-6 Motor Operation Precautions

1. When using the AC drive to operate a standard 3-phase induction motor, notice that the
energy loss is greater than an inverter duty motor.

2. While using the standard induction motor at low speed, the temperature of the motor may
rise, so do not operate the motor at low speed for a long period of time.

3. When the standard motor operates at low speed, the motor output torque will decrease,
please decrease the load during the operation.

4. If 100% output torque were desired at low speed operation, it may be necessary to use a
special motor that can handle this load (inverter duty).

NOTE: 1. DC Braking during Start-up is used for loads that may move before AC
drive starts, such as fans and pumps. These loads may also be moving
in the wrong direction. Under such circumstances, DC Braking can be
executed to hold the load in position before applying a forward motion.
2. DC Braking during stopping is used to decrease stopping time and also
to hold a stopped load in position. For high inertial loads, a dynamic
braking resistor may be needed for quick decelerations.

& When a momentary power loss is detected, the AC drive turns off for a
specified time interval determined by Pr.8-06 before resuming operation. This
time interval is called Base-Block. This parameter should be set to a value
where the residual output voltage is nearly zero, before the drive resumes
operation.

& After fault occurs (allowable faults: over-current OC, over-voltage OV), the AC
drive can be reset/restarted automatically up to 10 times. Setting this
parameter to 0 will disable the reset/restart operation after any fault has
occurred. When enabled, the AC drive will restart with speed search, which
starts at the Master Frequency. To set the fault recovery time after a fault,
please see (Pr.8-06) Baseblock Time for speed search.

 Chapter 5 Description of Parameter Settings

& AVR function automatically regulates the AC drive output voltage to the
Maximum Output Voltage (Pr.1-02). For instance, if Pr.1-02 is set at 200 VAC
and the input voltage is at 200V to 264VAC, then the Maximum Output Voltage
will automatically be regarded to 200 VAC.

& Without AVR function, the Maximum Output Voltage may vary between 180V
to 264VAC, due to the input voltage varying between 180V to 264 VAC.

& Selecting program value d2 enables the AVR function and also disables the
AVR function during deceleration. This offers a quicker deceleration.

8 - 16 Dynamic Braking Voltage Factory Setting: d 380*

Settings d 350 to d 450V* Unit: 1Volt*
*Twice value for 460V class

& During deceleration, the DC-bus voltage will increase due to motor
regeneration. When DC bus voltage level exceeds the Dynamic Braking
Voltage, the DC brake output pins (B1, B2) will be activated.

8 - 17 DC Braking Inhibit Frequency Factory Setting: d 0

Settings d 0 to d 400 Unit: 0.1 Hz

& This parameter determines the frequency range (from Pr.8-17 to 0 Hz) where
DC injection braking will be inhibited. If the output frequency during stopping
is at or below Pr.8-03, but above Pr.8-17 then DC braking is applied. 0DC
braking will always be inhibited if Pr.8-17 is equal to or greater than Pr.8-03.

 Chapter 6 Maintenance and Inspections

Chapter 6 Maintenance and Inspections

Modern AC drives are based on solid state electronics technology, preventive
maintenance is required to operate this AC drive in its optimal condition, and to
ensure a long life. It is recommended to perform a monthly check up of the AC
drive by a qualified technician. Before the check up, always turn off the AC Input
Power to the unit. Wait at least 2 minutes after all display lamps have gone out,
and then confirm that the capacitors have fully discharged.

CH 6-1 Periodic Inspection:

Basic check up items to detect if there were any abnormality during the
operation.

1. Whether the motors are operating as expected.

2. Whether the installation environment is abnormal.
3. Whether the cooling system is operating as expected.
4. Whether any irregular vibration or sound occurred during the operation.
5. Whether the motors are overheated during the operation.
6. Always check the input voltage of the AC drive with Voltmeter.

CH 6-2 Periodic Maintenance

It is necessary to stop the motor operation during the check up.
1. Tighten and reinforce the screws of the AC drive if necessary, cause it may
loose due to the vibration or changing of temperatures.
2. Whether the conductors or insulators were corroded and damaged.

 Chapter 6 Maintenance And Inspections

3. Check the resistance of the insulation with Megaohmeter.

4. If use of the AC drive is discontinued for a long period of time, turn the power
on at least once every two years and confirm that it still functions properly. To
confirm functionality, disconnect the motor and energize the AC drive for 5
hours or more before attempting to run a motor with it.
5. Clean off any dust and dirt with a vacuum cleaner. Place special emphasis on
cleaning the ventilation ports and PCBs. Always keep these areas clean, as
adherence of dust and dirt can cause unforeseen failures.

Chapter 7 Troubleshooting and Fault Information

The AC motor drive has a comprehensive fault diagnostic system that includes several different
alarms and fault messages. Once a fault is detected, the corresponding protective functions will
be activated to shut down the AC drive output. Below are the fault descriptions, for a fault
shown on the AC drive digital keypad display. The three most recent faults can be read on the
digital keypad display by viewing Pr.6-08 to Pr.6-10
NOTE: After faults occurred, press RESET to begin using the drive again.
