Chapter 3 Wiring
Installation notes:
NOTE
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
3. When applying to the external regenerative resistor, the contact between
4. When an alarm occurs or the system is in emergency stop status, use
