Note: The input power supply capacity is the capacity per axis.
The actual input current for the main circuit power supply will be the given value multiplied by the number of servo-
motor axes you control. Select the wire size according to the number of axes that you will use.

Cable
• Select a cable that can carry the rated current on three bundled lead wire pairs at a
surrounding air temperature of 40°C.
• Use wires with a withstand voltage of 100 V or higher.
• Use wires with an insulator outer diameter of 1.85 mm or less. You will not be able to
connect the cable to the connector if the outer diameter exceeds 1.85 mm.
• If wires are bundled in PVC or placed in metal ducts, take into account the reduction in
the allowable wire current.
• Use heat-resistant wire for high surrounding air or panel temperatures.
• The main circuit power supply cable and control power supply cable must not exceed
10 m.
