.4.2 Output frequency detection
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 above chart and set the corresponding parameters.
When Pr. 43 "output frequency detection for reverse rotation"
≠
"- - -", the Pr.42
setting applies to forward rotation and the Pr.43 setting applies to reverse rotation.
Use Pr. 64 or Pr. 65 (output terminal function selection) to assign the terminal used
for FU signal output.
CAUTION
Using Pr. 64 or Pr. 65 to change terminal assignment may affect the other functions.
Make setting after confirming the function of each terminal.
