◆ Wire Gauges and Tightening Torque
Use the tables in this section to select the appropriate wires and crimp terminals.
Note: 1. Wire gauge recommendations based on continuous current ratings using 75
°C 600 Vac vinyl-sheathed wire assuming ambient
temperature within 40
°C.
2. Wire gauge recommendations for terminals R/L1, S/L2, T/L3 on 4A0270 to 4A0630 based on continuous current ratings using 105
°C
600 Vac vinyl-sheathed wire assuming ambient temperature within 40
°C.
3. Use terminals and when connecting the drive to the converter.
Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is
greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following
formula to calculate the amount of voltage drop:
Line drop voltage (V) =
× wire resistance (Ω/km) × wire length (m) × current (A) × 10

Refer to
UL Standards Compliance on page 247
for information on UL compliance.
The wire gauges listed in
are Yaskawa recommendations. Refer to local codes for proper wire
gauge selections.
