4-5-5 Protecting power lines
We recommended protecting the driver by installing a circuit breaker or fuses from surge current at
power-ON. Select the recommended circuit breakers or fuses using the table below.

Note 3: The values are quoted for actuators and drivers for 200V power supply.
4-6 Connecting a ground wire
The minimum allowable size of ground wire is listed in the table below. Use the thickest wire possible.

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