Note 1. Refer to section 1.2 for the power supply specification.
2. For the case when 2 stations are occupied. When 1 station is occupied, the point table ends at No.31.
3. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor
does not stop immediately but coasts at emergency stop. Ensure the safety in the entire equipment.
