Note 1
•
The IS620P servo drive is directly connected to an industrial power supply, with no
isolation such as using a transformer. In this case, you need to connect a fuse or
molded-case circuit breaker (MCCB) on the input power supply to prevent cross electric
accidents in the servo system.
•
The IS620P servo drive has no built-in protective grounding circuit. Thus, connect a
residual-current circuit breaker (RCCB) against overload or short-circuit or a specialized
RCCB combined with the protective grounding.
•
Never use magnetic contactor for running or stopping the servo motor. Since motor is a
large inductance element, instantaneous medium voltage generated may damage the
contactor.
•
Pay attention to the power capacity when connecting an external power supply or 24
VDC, especially when the power supply is for powering up multiple drives or brakes.
Insufcient power supply will lead to lack of supply current, thus causing failure of the
drives or brakes. The brake shall be powered up by a 24 VDC power supply. For power
information, refer to the model of the motor.
