5. QUICK STARTING COMMISSIONING

5.1

Running the Motor for a Test

5.1.1 Inspection and preparation prior to powering on

Check the following prior to starting powering on.
(1) Check if connection is correct.
Especially check if the power wires are connected to the inverter input terminals L1/R, L2/S and L3/T, and output
terminals U, V and W respectively and that the grounding wires are connected to the ground electrodes correctly. Note
that FRENIC-Eco series inverter is designed for three phase input and driving three phase motors.
•
Do not connect power supply wires to the inverter output terminals U, V, and W. Otherwise, the inverter may
be broken if you turn the power on.
•
Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.
Otherwise, electric shock may occur.
(2) Check for short circuits between terminals and exposed live
parts and ground faults.
(3) Check for loose terminals, connectors and screws.
(4) Check if the motor is separated from mechanical equipment.
(5) Turn the switches off so that the inverter does not start or
operate erroneously at power-on.
(6) Check if safety measures are taken against runaway of the
system, e.g., a defense to protect people from unexpectedly
approaching your power system.

5.1.2 Turning on power and checking

Turn the power on and check the following points. This is
a case when no function code data is changed from the
factory setting.
(1) Check if the LED monitor displays "*00 " (means that the
frequency command is 0 Hz) that is blinking. (See Figure
5.2.)
If the LED monitor displays numbers except "*00 " then
press the
command.
(2) Check if a built-in cooling fan rotates.

5.1.3 Preparation before running the motor for a test--Setting function code data

Before starting running the motor, set function code data specified in Table 5.1 to the motor ratings and your system
design values. For the motor, check the rated values printed on the nameplate of the motor. For your system design
values, ask system designers about them.
For details about how to change function code data, refer to Chapter 4. Refer to the function code H03 in Chapter 6
&
"FUNCTION CODES" for the factory default setting of motor parameters. If any of them is different from the default setting,
change the function code data.
