Detailed instruction of parameters
0: No operation
1: Restore the default value
2: Clear fault records
Note: The function code will restore to 0 after finishing
the operation of the selected function code.
Restoring to the default value will cancel the user
password, please use this function with caution.
0: Start-up directly:start from the starting frequency
P01.01
1: Start-up after DC braking: start the motor from the
starting frequency after DC braking (set the parameter
P01.03 and P01.04). It is suitable in the cases where
reverse rotation may occur to the low inertia load during
starting.
2: Reserved.
Note: It is recommended to start the synchronous motor
directly.
Starting frequency of direct start-up means the original
frequency during the VFD starting. See P01.02 for
detailed information.
Setting range: 0.00–60.00Hz
Set a proper starting frequency to increase the torque of
the VFD during starting. During the retention time of the
starting frequency, the output frequency of the VFD is
the starting frequency. And then, the VFD will run from
the starting frequency to the set frequency. If the set
frequency is lower than the starting frequency, the VFD
will stop running and keep in the stand-by state. The
starting frequency is not limited in the lower limit
frequency.
