FR200 Series Vector control inverter
- 114 -
After power off, bus voltage is less than instantaneous power off bus voltage F11.30, and keep
instantaneous power off voltage judge time F11.32, inverter start to reduce the running frequency via
decel time at instantaneous power failure, the motor is in the state of power generation, the power
feedback to maintain the bus voltage to ensure the normal running of inverter until the bus voltage is
bigger than the instantaneous power off recovery voltage F11.31, then continue to run till the target
frequency.

Bus voltage constant control
After power off, bus voltage is less than the instantaneous power off bus voltage F11.30, inverter
will adjust the output frequency via PI adjustment F11.33 automatically

Notice
：
1. Proper adjustment of F11.25, can avoid production stop due tothe protection of the inverter
when power switch
2. Input phase lack protection function must be forbidden to enable this feature
F11.26
Rapid current limit
Range: 0
～
1
Default: 0
0: Disabled
1: Enabled
The rapid current limit function can reduce the AC drive's overcurrent faults at maximum,
guaranteeing uninterrupted running of the AC drive.However, long-time rapid current limit may cause
the AC drive to overheat, which is not allowed. In this case, the AC drive will report Err26, indicating
the AC drive is overloaded and needs to stop
F11.27
Times of automatic reset
Range:0
～
20
Default: 0
It is used to set the times of fault auto resets if this function is used. After the value is exceeded,
the AC drive will remain in the fault state.
F11.28
Interval of automatic reset
Range:0.1
～
100.0s
Default:1.0s
It is used to set the waiting time from the alarm of the AC drive to fault auto reset.
F11.29

reset
Range:0
～
1
Default: 0
0: Not act
1: Act
It is used to decide whether the DO acts during the fault auto reset if the fault auto reset function is
selected.
