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

  • 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.

Wire Selection Precautions

Think about line voltage drop before selecting wire gauges. Select wire gauges that drop the voltage by 2% or less of the rated voltage. Increase the wire gauge and the cable length when the risk of voltage drops increases. Calculate line voltage drop with this formula:

Line voltage drop (V) = × wire resistance (Ω/km) × wiring distance (m) × motor rated current (A) × 10-3.

Precautions during Wiring

  • Refer to “Yaskawa AC Drive Option Braking Unit, Braking Resistor Unit Instruction Manual (TOBPC72060001)” for information about wire gauges and tightening torques to connect braking resistor units.

  • Use terminals +1 and - to connect a regenerative converter or regenerative unit.
