Process
Operation
Reference
Installation and operation
environment
Install the inverter in a location meeting the technical specifications and
requirements of the product. Ensure the inverter can operate in the
anticipated environmental conditions, and the installation allows adequate
heat dissipation.
See
Chapters I,
2, 3.
Wiring of the inverter
Input terminals (LINE), output (motor) terminals; Grounding; Digital I/O
terminals, analog I/O terminals, and communication interface, etc.
See
Chapters 7
& 8.
Checking before
getting energised
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
Chapter 7
Checking immediately
after energised
Check if there is any abnormal sound, smell 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 Chapter
8
Inputting the parameters
indicated on the motor’s
nameplate correctly, and
measuring the motor’s
parameters.
Make sure to input the parameters indicated on the motor nameplate
correctly, and study the parameters of the motor. The users shall check
carefully, otherwise, serious problems may arise during running. Before
initial running with vector control mode, carry out tuning of motor
parameters, to obtain accurate electric parameters of the motor
controlled. Before carrying out tuning of the parameters, make sure to
disconnect the motor from mechanical load, to make the motor under
entirely no load status. It is prohibited to measure the parameters when
the motor is at a running status.

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
and abnormal noise.
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 and motor
immediately.
See
Chapter 8.
Checking under with
Load
After successful test run under no load, connect the load of drive system
properly. Start the inverter with the keypad or control terminal, and
increase the load gradually. When the load is increased to 50% and
100%, keep the inverter run for a period respectively, to check if the
system is running normally. Carry out overall inspection over the inverter
during running, to check if there is any abnormality. In case of any
abnormality, stop and check the inverter immediately.
Checking during running
Check if the motor is running stable, if the rotary direction of the motor is
correct, if there is any abnormal vibration or noise when the motor is
running, if the acceleration/deceleration process of the motor is stable, if
the output status of the inverter and the display of keypad panel is
correct, if the blower fan is run normally, and if there is any abnormal
vibration or noise. In case of any abnormality, stop the inverter
immediately, and check the system after switching off the power supply.
