2.5.2 Wiring instructions
Wiring Precautions
:
● Please perform the wiring with the shortest length, the length of the reference cable should be within 3m
and encoder cable is within 15m.
● Please perform the wiring according to the standard wiring diagram and the cable should not be connected
to the signal which is not assigned.
● Check whether the Power and connection of the power terminal R, S, T and L1C,L2C is correct, the Power
voltage of the servo motor drive is 220V, do not connect it to the 380V power.
● The phase sequence of the servo motor drive output terminal U, V, W must be corresponded to that of the
servo motor respectively, otherwise, it may cause servo motor stop or out of control.
● The method of exchanging the output terminal U, V, W to make the servo motor reversible does not work,
which is completely different with that of the synchronous servo motor, please do not use it.
● Perform ground wires, the ground resistance is 100Ω or below and single ground. If the insulation
state between the servo motor and machine is required, please make the servo motor ground wire.
● The direction of the diode for absorbing on the output signal relay must be connected correctly, otherwise, it
may cause fault and disable the output signal.
● In order to avoid the error action due to the noise, please add the insulation transformer and noise filter to
the power.
● Please do not install the capacitor, overvoltage absorber and noise filter to the servo motor drive output
● Please wire the cable (power line, servo motor line and strong circuit) and the signal cable with 30m or
above and do not put into the same wiring instrumentation to avoid the interference causing the error
action.
● Please install the non-fuse circuit breaker to cut off the Power when the servo motor drive fault occurs.
● Normally, fixing the regenerate braking unit is unnecessary, if any requirement, please contact with the
manufacturer or distributor.
2.5.3 Example for main circuit /control circuit power

!
CAUTION
1.The input Power stated by servo motor drive should be used(voltage level and frequency)
2.Wrong wiring of U, V, W will lead that the servo motor can not work normally, so please carry out the wiring
correctly!
