Revision May, 2018
NOTE
Installation notes:
1. Check if the power and wiring among R, S, T and L1c, L2c are correct.
2. Please check if the output terminal U, V, W of the servo motor is correctly
wired. The incorrect wiring may disable the operation of the motor or cause
malfunction.
3. When applying to the external regenerative resistor, the contact between
P
and D should be opened and the external regenerative resistor should
connect to terminal P
and C. When applying to the internal regenerative
resistor, the contact between P
and D should be closed and the contact
between P
and C should be opened.
4. When an alarm occurs or the system is in emergency stop status, use
ALARM or WARN to output and disconnect the power of magnetic
contactor in order to disconnect the power of servo drive.
