Servo Motor & Drive Wiring Diagram
No-Fuse Breaker (NFB)
To prevent the large instant
current received by the
power-on, power-off or the
short circuit and damage
the drive.
Magnetic Contactor (MC)
When fault alarm was
received,the servo drive
could be used together to
output alarm signal (ALARM)
and control the contactor
(MC),and stop the servo
drive power.
External retrogradation
resistor
( optional )
Installation Notes:
1. Check the R, S, T and the L1C ,L2C power and connecting wire.
2. Check the servo motor output U, V, W terminal phase wires (Unable to run when the connection is wrong).
3. External connected regeneration resistor is the selective spare, adopt according to the actual needs.
4. When fault or emergent stop was received, cut the power of magnetic contactor (MC) through ALARM output
to stop the power of drive.
