2. In order to ensure dynamic control performance of the inverter, set F800=1, i.e. select stator resistance
parameter measurement. Press the “Run” key on the keypad, and the inverter will display “TEST”, after
few seconds, self-checking is completed, motor stator resistance parameters will be stored in function code
F806, and F800 will turn to 0 automatically.

Operation
Reference
Installation and
operation environment
Install the inverter at a location meeting the technical
specifications and requirements of the product. Mainly take into
consideration the environment conditions (temperature, humidity,
etc) and heat radiation of the inverter, to check whether they can
satisfy the requirements.
See Chapters I, II,
III.
Wiring of the inverter
Wiring of input and output terminals of the main circuit; wiring
of grounding; wiring of switching value control terminal,
analog terminal and communication interface, etc.
See Chapter III.
Checking before
getting energized
Make sure that the voltage of input power supply is correct; the input
power supply loop is connected with a breaker; the inverter has been
grounded correctly and reliably; the power cable is connected to the
power supply input terminals of inverter correctly (R/L1, S/L2 terminals
for single-phase power grid, and R/L1, S/L2, and T/L3 for three-phase
power grid); the output terminals U, V, and W of the inverter are
connected to the motor correctly; the wiring of control terminals is
correct; all the external switches are preset correctly; and the motor is
under no load (the mechanical load is disconnected from the motor).
See Chapters I

III
Checking immediately
after energized
Check if there is any abnormal sound, fuming or foreign flavor
with the inverter. Make sure that the display of keypad panel is
normal, without any fault alarm message. In case of any
abnormality, switch off the power supply immediately.
See Appendix 1
and Appendix 2.
Inputting the parameters
indicated on the motor‟s
nameplate correctly, and
measuring the motor stator
resistance parameters.
Make sure to input the parameters indicated on the motor
nameplate correctly, and measure the motor stator resistance
parameters to get the best control performance.
See description of
parameter group
F800~F830
Setting running control
parameters
Set the parameters of the inverter and the motor correctly, which
mainly include target frequency, upper and lower frequency limits,
acceleration/deceleration time, and direction control command, etc.
The user can select corresponding running control mode according
to actual applications.
See description of
parameter group.
Checking under
no load
With the motor under no load, start the inverter with the keypad or
control terminal. Check and confirm running status of the drive
system. Motor‟s status: stable running, normal running, correct
rotary direction, normal acceleration/deceleration process, free from
abnormal vibration, abnormal noise and foreign flavor. Inverter‟
status: normal display of the data on keypad panel, normal running
of the fan, normal acting sequence of the relay, free from the
abnormalities like vibration or noise. In case of any abnormality,
stop and check the inverter immediately.
