PARAMETERS
4.2.19 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 frequency detection 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 173 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.
