1: Restore default settings except motor parameters
If A0-09 is set to 1, most function codes are restored to the default settings
except
motor parameters, frequency
command resolution (b0-11), fault records, accumulative running time (b9-08), accumulative power-on time
(b9-09).
2: Restore default settings include motor parameters
If A0-09 is set to 2, most function codes are restored to the default settings
include
motor parameters, frequency
command resolution (b0-11), fault records, accumulative running time (b9-08), accumulative power-on time
(b9-09).
4: Clear records
If A0-09 is set to 4, the fault records, accumulative running time (b9-08), accumulative power-on time (b9-09) are
cleared.

A2-00
Current limit level
Default
150%
Setting Range
50%~200%
A2-01
Current limit selection
Default
1
Setting Range
0~1
A2-02
Current limit gain
Default
20
Setting Range
0~100
A2-03
Compensation factor of speed multiplying current limit
Default
50%
Setting Range
50%~200%
In high frequency area, motor drive current is small. Bigger motor speed dip is caused by current limit level
compared with below rated frequency. To improve motor running characteristic, you can lower current limit level above
rated frequency.
The current limit function above rated frequency helps to improve acceleration performance in the applications,
such as centrifuge, where high running frequency and several times of field weakening are required, and load inertia is
large.
A2-04
Voltage limit
Default
760V
Setting Range
200.0V~2000.0V
A2-05
Voltage limit selection
Default
1
Setting Range
0~1
A2-06
Frequency gain for voltage limit
Default
30
Setting Range
0~100
A2-07
Voltage gain for voltage limit
Default
30
Setting Range
0~100
A2-08
Frequency rise threshold during voltage limit
Default
5Hz
Setting Range
0~50Hz
The increase of A2-06 improves the control effect of the bus voltage, but the output frequency can fluctuate, and if the
fluctuate is large, can reduce A2-06 appropriately.
Note:
when using a braking resistor or when installing a brake unit or energy feedback unit:
