Items to Check

Description

Input Power Supply Voltage

The voltage of the input power supply must be:

200 V class: three-phase 200 Vac to 240 Vac 50/60 Hz, 270 Vdc to 340 Vdc

400 V class: three-phase 380 Vac to 480 Vac 50/60 Hz, 510 Vdc to 680 Vdc

Correctly and safely wire power supply input terminals R/L1, S/L2, T/L3.

Correctly ground the drive and motor.

Connection between Drive Output Terminals and Motor Terminals

Make sure that you connected drive output terminals U/T1, V/T2, and W/T3 in the correct sequence to agree with motor terminals U, V, and W without loosened screws.

Control Circuit Terminal Wiring

Make sure that you connected the drive control circuit terminals in the correct sequence to agree with devices and switches without loosened screws.

Control Circuit Terminal Status

Turn OFF the inputs from all devices and switches connected to the drive control circuit terminals.

Connection between Machinery and Motor

Disengage all couplings and belts that connect the motor and machinery.
