Installation precautions:
1. Make sure the power and wiring connections of the R, S, T, and L
the specifications of the servo drives in Appendix A 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 an external regenerative resistor is used, P3 and D contacts should be left open, and
the external regenerative resistor should connect to P3 and C contacts. When the built-in
regenerative resistor is used, 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.ALRM or
DO.WARN to switch off the magnetic contactor (MC) to cut off the power to the servo drive.
