Wiring and Connection
∗1. Do not short-circuit the B1/ and B2 terminals. Doing so may damage the SERVOPACK.
∗2. The 1 and 2 terminals are short-circuited with a jumper at the factory.
3.1.2 Using a Standard Power Supply Input (Single-phase 100-V, Three-phase
200-V, or Three-phase 400-V)
(1) Wire Types
Use the following type of wire for main circuit.
The following table shows the wire sizes and allowable currents for three wires. Use wires with specifications equal to or
less than those shown in the table.
