3-3 Performing a Test Run
This section describes performing a test run. Refer to Chapter 2 Design for information on Inverter
installation and wiring.
■
Confirmation before Performing a Test Run
• Confirm that all installation conditions have been met.
• Confirm that peripheral devices that conform to all specifications have been used and that they are
wired correctly.
■
Checkpoints before Connecting the Power Supply
• Check that the power supply is of the correct voltage and that the power input terminals (R/L1, S/
L2, and T/L3) are connected correctly.

: Three-phase 200 to 230 V AC
• Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are connected to the motor cor-
rectly.
• Make sure that the control circuit terminals and the control device are wired correctly. Make sure
that all control terminals are turned OFF.
• Set the motor to no-load status (i.e., not connected to the mechanical system).
■
Connecting the Power Supply
• After conducting the above checks, connect the power supply.
• The entire display and setting/monitoring indicators will light (except for the COM indicator) when
the power supply is turned ON. The display and indicators will read as follows if the Inverter is nor-
mal.
Data display:
Shows the present frequency reference.
Simplified-LED indicators: Only frequency reference indicator (Hz set) will be lit.
• If an error has occurred, the error parameter will be displayed on the data display.
If that occurs, refer to Chapter 4 Maintenance Operations and take the required action.
■
Using Parameter Initialization (P20)
• Initialize the parameters using the following procedure before performing a trial run. When the
parameters are initialized, all values except for the accumulated operating time will be returned to
their default settings.
