Output Frequency Detection (Pr. 42, Pr. 43) - Mitsubishi Electric FR-E 500 Instruction Manual

4.2.19 Output frequency detection (Pr. 42, Pr. 43)

" Output frequency detection (Pr. 42, Pr. 43)
Pr. 42 "output frequency detection"
Pr. 43 "output frequency detection for
reverse rotation"
The output frequency detection signal (FU) 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 switching the timing of electromagnetic brake operation
between forward rotation (rise) and reverse rotation (fall) during vertical lift operation
etc.

<Setting>
Refer to the figure below and set the corresponding parameters:
! When Pr. 43 ≠ 9999, the Pr. 42 setting applies to forward rotation and the Pr. 43
setting applies to reverse rotation.
! Assign the terminal used for FU signal output with any of Pr. 190 to Pr. 192
(output terminal function selection).
Refer to page 150 for Pr. 190 to Pr. 192 (output terminal function selection).
Note: Changing the terminal assignment using Pr. 190 to Pr. 192 may affect the
other functions. Make setting after confirming the function of each terminal.
