P11.19
Frequency arrival (FAR)
detection width
range:0.00Hz~maximum
frequency
Factory
default:2.50Hz
It is used for detecting the deviation between the output frequency and the setting frequency; when
the deviation between the output frequency and the setting frequency is within the range of this function
code, and the output terminal is set to the "frequency reaching FAR" function, a valid signal is output.

P11.22
Zero current detection level
range:0.0%~50.0%
Factory default:5.0%
P11.23
Zero current detection time
range:0.00s~50.00s
Factory
default:0.50s
The output terminal function is set to "zero current detection", when the variable frequency drive is
in the running status, and the output current is less than the setting level of P11.22, the duration is
greater than the time of P11.23, then a valid signal is output.
The zero current detection level is a percentage relative to the rated current of the variable
frequency drive.
