Attention：
Danger
It is not permitted to conduct unauthorized modification in case of the danger of
fire/electric shock and other hurt！
Installation must be conducted by qualified personnel in case of the danger of
electric shock！
Please install the inverter on the metal equipmen(supplementary enclosure) or
other non-combustible objects in case of the danger of fire!
It is not permitted to place combustibles nearby in case of the danger of fire!
The products should be installed with either fuses or an input circuit breaker
between the inverter and power supply in case of danger of fire!
It is not permitted to install the inverter in an environemnt containing explosive
gases in case of the danger of explosion!
It is not permitted to insall the inverter at a place directly exposed in sunlight in
case of the danger of equipment damage!
It is not permitted to install the inverter on occasions where water splashing in

5.2 Simple Commissioning Process
Power on
Need motor
auto tuning
Confirm the main
circuit and control
circuit correct
Select motor
control mode by
parameter F0.00
Set parameter F2.22
to 1, press RUN key
to conduct static
motor auto tuning
Can disconnect
motor load?
Input the correct motor
nameplate data
Set parameter F2.22
to 2, press RUN key
to conduct rotate
motor auto tuning
Set reference frequency by
parameter F0.05
When the inverter is ready, press Run key to start
the motor without load, measure and check the 3-
phase current balance
After testing completed, stop the inverter, prepare
to set other parameters as equipment required
Input the correct motor nameplate
data in parameter group F2
(F2.01~F2.06)
Set NVF5 motor control mode according
to parameter F0.00 definition. The default
mode is V/F control.
After power on, the default 5.00Hz
will be displayed on NVF5 integral
keypad screen normally
Set Accel. and Decel. time Set Accel.time and
Decel.time by parameter
F0.14 and F0.15
Default reference frequency is
5.00Hz. It can be changed as
required.
Yes
No
Refer to Chapter 3 -“Installation
and Wiring”for check correct
wiring
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
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
After testing completed, stop the inverter
and set other parameters as required
Record the current value and parameters
Run the motor at 5.00Hz and
check the motor running direction
If the motor runs reverse,
change parameter F0.06 or
change the 3-phase motor
cables.
Yes
No
