5.2 Simple Commissioning Process

Confirm the main circuit and control circuit correct

Power on

Select motor control mode by parameter F0.00

Input the correct motor nameplate data

Refer to Chapter 3 -

“

Installation and Wiring

”

for check correct wiring

After power on, the default 5.00Hz will be displayed on NVF5 integral keypad screen normally

Set NVF5 motor control mode according to parameter F0.00 definition. The default mode is V/F control.

Input the correct motor nameplate data in parameter group F2

(F2.01~F2.06)

Need motor auto tuning

No

Yes

Can disconnect motor load?

No

Set parameter F2.22 to 1, press RUN key to conduct static motor auto tuning

Run the motor at 5.00Hz and check the motor running direction

Set reference frequency by parameter F0.05

Set Accel. and Decel. time

When the inverter is ready, press Run key to start the motor without load, measure and check the 3phase current balance

If the inverter is running normally without load, the inverter can be tested with load, measure and confirm the 3-phase current balance, and also confirm the current less than rated motor current

After testing completed, stop the inverter, prepare to set other parameters as equipment required

Yes

Set parameter F2.22 to 2, press RUN key to conduct rotate motor auto tuning

If the motor runs reverse, change parameter F0.06 or change the 3-phase motor cables.

Default reference frequency is

5.00Hz. It can be changed as required.

Set Accel.time and

Decel.time by parameter

F0.14 and F0.15

The output current value of inverter is almost the same as the value displayed on integral keypad of NVF5

， motor running direction refer to parameter F0.06

Record the current value and parameters

After testing completed, stop the inverter and set other parameters as required
