Main Circuit Wire Gauges and Tightening Torques

When you use stranded wires and need the same workability and simplicity of wiring as crimp terminals, Yaskawa recommends that you use crimp ferrules. Refer to Crimp Ferrules for recommended crimp ferrules.

Note:
  • The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class 2 heat-resistant indoor PVC wire. Assume these conditions:

    • Ambient temperature: 40 °C (104 °F) maximum

    • Wiring distance: 100 m (3281 ft) maximum

    • Normal Duty rated current value

  • Use terminals +1, +2, -, B1, and B2 to connect peripheral options, for example a DC reactor or a braking resistor. Do not connect other items to these terminals.

  • Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals +1, +2, -, B1, and B2. Contact Yaskawa or your nearest sales representative if the recommended wire gauges for the peripheral devices or options are out of the range of the applicable gauges for the drive.

  • When you use crimp ferrules on the wire ends, contact Yaskawa or your nearest sales representative.
