Up-To-Frequency Sensitivity (Pr. 41); Output Frequency Detection (Pr. 42, Pr. 43, Pr. 50, Pr. 116) - Mitsubishi Electric FR-A520-0.4K Instruction Manual

4.2.18 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 confirm that the running frequency has been reached or used as the
operation start signal etc. for related equipment.

Note: Changing the terminal assignment with any of Pr. 190 to Pr. 195 may affect the other functions. Make
setting after checking the functions of the corresponding terminals.

4.2.19 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
effective for changing the timing of electromagnetic brake operation between forward rotation (rise) and
reverse rotation (fall) during vertical lift operation, etc.
