Please observe the following precautions while performing wiring and touching any electrical connections on

the servo drive or servo motor.

1) Ensure to check if the power supply and wiring of the "power" terminals (R, S, T, L1, L2, U, V, & W) is

correct.

2) As a residual hazardous voltage may remain inside the drive, please do not immediately touch any of the

"power" terminals (R, S, T, L1, L2, U, V, & W) and/or the cables connected to them after the power has

been turned off and the charge LED is lit. (Please refer to the Safety Precautions on page ii).

3) The cables connected to R, S, T and U, V, W terminals should be placed in separate conduits from the

encoder or other signal cables. Separate them by at least 30cm (12").

4) For the connectors and cables specifications, please refer to section 3-1-6 for details.

3-1-3 Wiring Methods

For drives from 100W to 1kW the input power can be either single or three-phase. For drives 1.5kW and

above only three-phase connections are available.

In the wiring diagram figures 3.2 & 3.3:

Power ON : contact “a” (normally open).

Power OFF or Alarm Processing : contact “b” (normally closed).

1MC/x : coil of electromagnetic contactor

1MC/a : self-holding power

1MC : contact of main circuit power.
