Wire Gauges And Tightening Torques - YASKAWA FSDrive-MV1000 Instructions Manual

3.5 Main Circuit Wiring

◆ Wire Gauges and Tightening Torques

Select the appropriate wires and crimp terminals from the table below.
Consider the voltage drop when selecting wire gauges.
Select the wire gauge so that the voltage drop can be limited to within 2% of the motor rated voltage. If there is a risk of
a drop voltage, increase the wire gauge in accordance with the length of the cable. Use the following formula to calculate
the line drop voltage:
Line drop voltage (V) =
Note: The following conditions are assumed about the operating environment of the recommended wires for main circuit use.
ambient temperature of 40°C max., wiring distance less than 100 m, and use at the rated current value.
Class: 2 kV
