frequency and fault output.
For hoisting equipment, the following protection settings shall be
invalid: Current limit protection and overvoltage stall protection.
Motor Parameter
Autotuning
Before running for the first time, please conduct motor parameter
autotuning, in order to obtain the correct electrical parameters of
the controlled motor.
If motor load cannot be removed, select motor stationary
autotuning (F01.34=
1/11
); afterwards, press of keypad
first and then press .
If motor is still running, do not conduct motor parameter
autotuning operation.
Operation
Control
Parameter
Setting
Correctly set rotational direction, forward/reverse control,
acceleration/deceleration time, driving mode, start/stop mode,
speed torque control mode and other parameters according to the
working conditions of the driving system.
Set function parameters including the V/F curve, stator voltage
drop compensation and slip compensation, according to the load
demands.
Set regulator parameters according to the load.
Idling Trial Operation
Check
When motor is idling, start inverter at a low speed or allow it for
jog running, and check and confirm the running status of driving
system:
Motor: Motor runs stably and rotates normally and correctly; the
acceleration/deceleration process is normal, free of abnormal
vibration, noise and foreign odor.
Inverter: Operation panel displays data normally, fan rotates
normally and relay acts normally, free from vibration and foreign
odor.
In case of abnormal condition, immediately stop it and cut the
power for checking.
On-Load Trial
Operation Check
Conduct on-load trial operation check only after inverter has
passed no-load operation check satisfactorily, .
