The inverter can be selected to detect whether the motor is shorted to
ground when it is powered on.
If this function is enabled, the UVW terminal of the inverter will have a
voltage output for a period of time after power-on.
P9-08
Brake unit action
starting voltage
200.0~2000.0V
Default
：
690
The starting voltage Vbreak of the built-in braking unit action, the setting of
this voltage value is as follows:
800 ≥ Vbreak ≥ (1.414Vs+30)
Vs- Input AC power supply voltage of the inverter Note: Improper setting of
this voltage may cause the built-in brake unit to operate abnormally!
P9-09
Number of automatic resets
0
〜
20
Default
：
0
When the inverter selects fault automatic reset, the number of automatic
resets can be set. After the number of times, the inverter outputs a fault status.

When the fault automatic reset function is set in the inverter, the fault
output is activated during the automatic fault reset.
P9-11
Fault auto reset interval

Default
：
1.0s
The waiting time from the inverter fault alarm to the automatic fault reset.
P9-12
Input phase loss protection
option
0: Prohibited
1: Allowed
Default
：
1
The inverter has the input phase loss protection function from the 18.5kW
G type machine and above. The power of the 18.5kW P type machine has no
input phase loss protection function regardless of whether P9-12 is set to 0
or1
Choose whether to protect the input phase loss.
