Preparing for Operation

4-3 Test Run

After wiring is complete, perform a test run of the Inverter as follows. First,
start the motor through the Digital Operator without connecting the motor
to the mechanical system. Next, connect the motor to the mechanical sys-
tem and perform a test run. Finally, operate the controller to make sure that
the sequence of operations is correct.
This section only describes how to perform a test run using the Digital
Operator.

4-3-1 Checking Wiring

•Check that terminals R, S, and T receive power supply.
200-VAC Class
Three-phase input: 200 to 230 VAC, 50/60 Hz
Single-phase input: 200 to 240 VAC, 50/60 Hz (terminal R and S)
(Single-phase input is only applicable to 3G3EV-ABjjj.)
400-VAC Class
Three-phase input: 380 to 460 VAC, 50/60 Hz
•Check that terminals U, V, and W are correctly connected to the motor power cables.
•Do not connect the mechanical system to the motor. (The motor must be in no-load
status.)
•If signal lines are connected to control terminals, turn terminals SF and SR off.

4-3-2 Turning Power On and Checking Indicator Display

•Check that the ALARM indicator is not lit.
•Check that the RUN indicator is flashing.

4-3-3 Initializing Constants

•Set "8" or "9" (3-wire sequence mode) in constant no. 01 to initialize constants.

4-3-4 Setting a V/f Pattern

•Set the maximum frequency ("FMAX" or constant no. 24), maximum voltage ("VMAX"
or constant no. 25), and maximum voltage frequency ("FBAS" or constant no. 26) ac-
cording to the operating conditions.
