Installation safety precautions:
1. Make sure the power and wiring connections between the R, S, T, and L
Refer to Appendix A Specifications for the correct voltage input to avoid any damage to the
servo drive and dangerous operating conditions.
2. Make sure the UVW terminal block is correctly wired to avoid abnormal operation of the
motor.
3. When installing an external regenerative resistor, P3 and D contacts should be left open,
and the external regenerative resistor should connect to P3 and C contacts. When using the
built-in regenerative resistor, P3 and D contacts should be short-circuited, and P3 and C
contacts should be left open.
4. When an alarm occurs or the system is under emergency stop status, use DO.ALARM or
DI.WARN to disconnect the power at the magnetic contactor (MC) so as to power off the
servo drive.
