◆ Wire Gauges and Tightening Torque
Select the appropriate wires and crimp terminals from Table 3.2 through Ta ble 3.5.
• 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 x wire resistance (Ω/km) x wire length (m) x current (A) x 10
-3
Refer to instruction manual TOBPC72060000 for braking unit or braking
resistor unit wire gauges.
• Refer to Standards Compliance on page 435 for information on UL compliance.
Note: 1. Wire gauge recommendations based on drive continuous current ratings using 75°C 600
Vac vinyl-sheathed wire assuming ambient temperature within 30°C and wiring distance
less than 100 m.
2. Terminals +1, +2, –, B1 and B2 are for connecting optional devices such as a DC reactor or
braking resistor. Do not connect other non-specified devices to these terminals.
