Chapter 4 Installing HA-655 driver<br />
4-5-5Protecting power lines<br />
We recommended protecting the driver by installing a circuit breaker or fuses from surge current at<br />
power-ON. Select the recommended circuit breakers or fuses using the table below.<br />

Note 1: The value is for continuous duty at rated output.<br />
Note 2: The values are quoted at ambient temperature of 25 degC.<br />
Note 3: The values are quoted for actuators and drivers for 200V power supply.<br />

The HA -655 driver provides two ground terminals as shown<br />
the figure to the right. Connect the ground wire from the<br />
cabinet to either terminal and connect the ground wire from<br />
the actuator to the other terminal.<br />
The leakage current is at least 3.5 mA. Therefore terminals<br />
must have a section of at least 3.5 mm 2 and be wired using<br />
ring terminals.<br />
4-7Connecting motor and regeneration resistor cables<br />
Connect the actuator cable to [U,V,W] terminals of the HA-655 driver as shown in the figure below. Refer<br />
to the phase order of the actuator cable in the actuator manual and connect the end terminal of cables to<br />
the driver terminal that have the same symbol.<br />
Shown the figure to the right, strip the end of wires of the motor cable<br />
and resistor cables, and connect wires to each terminal firmly.<br />
When a regeneration resistor is required, connect its wires to [R1, R2]<br />
terminals.<br />
