Wire Gauges and Tightening Torque
Select the appropriate wires and crimp terminals from Table 3.3 through Table 3.4.
Note: 1. Wire gauge recommendations based on drive continuous current ratings using 75°C 600 Vac vinyl-sheathed wire assuming ambient
temperature within 40°C and wiring distance less than 100 m.
2. Terminals +1, +2, +3, and – are for connecting optional devices such as a DC reactor or braking unit. Do not connect other
nonspecific devices to these terminals.
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) × motor rated current (A) × 10

Refer to instruction manuals TOBPC72060000 and TOBPC72060001 for braking unit or braking resistor unit wire
gauges.
NOTICE: Do not connect a braking resistor to terminals +1 and -. Failure to comply may cause damage to the drive circuitry.
Use terminal +1 and the negative terminal when connecting a regenerative converter, or a regen unit.
Refer to UL Standards Compliance on page 446 for information on UL compliance.
Yaskawa recommends using closed-loop crimp terminals on all drive models. UL/cUL approval requires the use of
closed-loop crimp terminals when wiring the drive main circuit terminals on models CIMR-E2A0110 to 2A0415 and
4A0058 to 4A1200. Use only the tools recommended by the terminal manufacturer for crimping. Refer to Closed-Loop
Crimp Terminal Size on page 450 for closed-loop crimp terminal recommendations.
The wire gauges listed in the following tables are Yaskawa recommendations. Refer to local codes for proper wire gauge
selections.
