F1.4.47 Current limit trip level
Setting range: 20~200%
Factory default: 190
F1.4.48 Current limit trip level
gain
Setting range: 0.10~10.00
Factory default: 1.00
When the output current of frequency inverter exceeds [F1.4.47], it may lower output frequency automatically
to suppress current from further increasing, to ensure continually safe running. The bigger (F1.4.48) gain is,
the stronger current suppression is. Setting value is relevant percentage of rated output current of frequency
inverter.
F1.4.49 Number of auto reset
attempts
Setting range: 0~5
Factory default: 0
F1.4.50 Time between auto
resets
Setting range: 0.2~100.0Sec.
Factory default: 1.0
F1.4.51 Auto reset cycle time
Setting range: 900~36000Sec.
Factory default: 3600
Fault self resetting refers to that when the frequency inverter breaks down, with a period of time, fault self
resetting can be operated and recover to run with starting way of speed inspection. When accumulated
resetting times exceeds setting value [F1.4.49], self resetting action terminates. When self resetting time
[F1.4.49] is set as zero, it means this function is banned.
Recovery waiting time of fault self resetting gets longer with resetting times: waiting time=[F1.4.50] * already
reset times
Each time it passes the set parameter period [F1.4.51], or external forced fault reset, it will automatically
eliminate one self resetting record.
F1.4.53 Display coefficient
Setting range: 0.001~60.000
Factory default: 1.000
It is used for correction values of monitoring parameters (d0.0.00, d0.0.01, d0.0.9, d0.0.10), to match with
site parameters.
