NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring practices could result in drive malfunction due

to loose terminal connections.

Select the appropriate wires and crimp terminals from

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.

• 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

• Refer to instruction manual TOBPC72060000 for braking unit or braking resistor unit wire gauges.

Table 3.1 Main Circuit Terminal Functions

Type

Connects line power to the drive.

Drives with single phase 200 V input power use terminals R/L1 and S/L2 only (T/L3 must not be used).

Connects to the motor.

Available for connecting a braking resistor or the braking resistor unit option.

These terminals are shorted at shipment. Remove the shorting bar between +1 and +2 when connecting to this

terminal.

For connecting a DC power supply.

Grounding Terminal

For 200 V class: 100 Ω or less

For 400 V class: 10 Ω or less
