FUNCTIONS
2.4.2 Output frequency detection (Pr. 42 , Pr. 43 )
<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.
, Refer to , (page 78).
Refer to (page 73).
Refer to (page 75).
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.
