Up-to-frequency sensitivity (Pr. 41)

Pr. 41 "up-to-frequency sensitivity"
The ON range of the up-to-frequency signal (SU) output when the output frequency reaches the running
frequency can be adjusted between 0 and ±100% of the running frequency.
This parameter can be used to ensure that the running frequency has been reached or used as the operation
start signal etc. for related equipment.

Output frequency detection (Pr. 42, Pr. 43, Pr. 50, Pr. 116)

Pr. 42 "output frequency detection"
Pr. 43 "output frequency detection for reverse rotation"
Pr. 50 "second output frequency detection"
Pr. 116 "third output frequency detection"
The output frequency signal (FU, FU2, FU3) is output when the output frequency reaches or exceeds
the setting. This function can be used for electromagnetic brake operation, open signal, etc.
You can also set the detection of the frequency used exclusively for reverse rotation. This function is
z
effective for switching the timing of electromagnetic brake operation between forward rotation (rise) and
reverse rotation (fall) during vertical lift operation, etc.
