1.5 Wiring Precautions
CAUTION
CAUTION
u
NEVER connect a power supply to the output terminals U, V, and W of the drive. Failure to
comply may result in personal injuries or a re.
u
Connect the U, V, and W cables of the drive to the U, V, and W terminals of the motor
directly. Do not connect an electromagnetic contactor. Failure to comply may result in faults.
u
When connecting DO terminals to relays, pay attention to the polarity of the ywheel diode.
Otherwise, the drive will be damaged and signal output becomes abnormal.
u
Connect the power terminals and motor terminals securely. Failure to comply may result in
a re.
u
Do not lead the power cable and signal cables through the same duct or bundle them
together. Separate power cables at least 30 cm from signal cables.
u
Use the twisted shielded cables as the signal cables and encoder cables, and ground both
ends of the shield.
u
The maximum length of reference input cables is 3 m, and that of encoder cables is 20 m.
u
Wait at least ve minutes before touching the power terminals because high voltage may
still be present in the servo drive after the power is switched off.
u
Perform check after conrming that the CHARGE indicator is OFF.
u
Do not switch on/off the power frequently. If repeated power-on/off operations are required,
perform an operations at an interval of at least one minute.
u
The servo drive contains a capacitor in the power supply module, and a high current ows
for 0.2 second after the servo drive is switched on/off. Frequently switching on/off the servo
drive will deteriorate the performance of the main circuit components inside the drive.
u
Observe the following precautions when wiring the main circuit:
1. Remove the connectors from the drive when wiring.
2. Only one cable can be inserted into one interface of the connector. Prevent short-circuit
between the core and adjacent cables when inserting the cable.
3. Do not connect a 220 V drive to a 380 V power supply. Failure to comply will result in
damages to the drive.
4. Connect the cables correctly and securely. Failure to comply may make the motor out of
control, or cause personal injuries or faults.
5. Use the specied power supply. Otherwise, the drive may be damaged.
6. When the power supply is poor, ensure that voltage uctuation is within the permissible
range. Failure to comply may result in damages to the equipment.
