Terminal Block Wire Sizes
The following tables show the rated current that flows to the terminal block on the Servo Drive
and the applicable wire sizes. Use the wire with the rated voltage of 600 V or higher for the main
circuit.
The wire size is determined for when the heat-resistant polyvinyl chloride insulated wire (HIV)
is used at the ambient temperature of 50°C.
