Three-phase AC 
power supply
Use within the allowable power supply 
specification of the servo drive.
Select a proper circuit breaker to resist 
large in-rush current that flows into the 
AC drive at power-on.
Reliably ground the motor and the 
servo drive to prevent electric shock.
Suppress the high order harmonic to 
improve the power factor.
Braking resistor
EMC filter on 
the input side
To guarantee safety, use an 
electromagnetic contactor. Do not use 
it to start or stop the AC drive because 
such operation reduces the service life 
of the servo drive.
Reduce the electromagnetic 
interference on the input side.

Note
 
•
Never install the capacitor or surge suppressor on the output side of the AC drive. Otherwise, it may 
cause faults to the AC drive or damage to the capacitor and surge suppressor.
 
•
Inputs/Outputs (main circuit) of the AC drive contain harmonics, which may interfere with the 
communication device connected to the AC drive. Therefore, install an anti-interference lter to 
minimize the interference.
