u Main Circuit Wire Gauges and Tightening Torque
Use the tables in this section to select the appropriate wires and crimp terminals.
Gauges listed in the tables are for use in the United States.
Note: 1. Wire gauge recommendations based on drive continuous current ratings (ND) 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, –, B1 and B2 are for connecting optional devices such as a DC link choke or braking resistor. 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) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10
-3
• Refer to instruction manual TOBP C720600 00 for braking transistor option or braking resistor option wire gauges.
• Use terminals +1 and – when connecting a regenerative converter or a regen unit.
NOTICE: Do not connect a braking resistor to terminals +1 or –. Failure to comply may cause damage to the drive circuitry.
• Use terminals B1 and – when installing a CDBR-type braking unit on drives with built-in braking transistors (models 2A0004
to 2A0138, 4A0002 to 4A0072, and 5A0003 to 5A0052).
• Refer to UL Standards Compliance on page 244 for information on UL compliance.
Yaskawa recommends using closed-loop crimp terminals on all drive models. To maintain UL/cUL approval, UL Listed
closed-loop crimp terminals are specifically required when wiring the drive main circuit terminals on models 2A0110 to
2A0415, 4A0058 to 4A1200, and 5A0041 to 5A0242. Use only the tools recommended by the terminal manufacturer for
crimping. Refer to Closed-Loop Crimp Terminal Size on page 244 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.
