Function assignment of external terminals
Output frequency detection (FU, Pr. 42, Pr. 43)
The output frequency detection signal (FU) is output when the output frequency reaches or exceeds
the Pr. 42 setting. This function can be used for electromagnetic brake operation, open signal, etc.
When the detection frequency is set to Pr. 43, frequency detection for reverse operation use only can
also be set. This function is effective for switching the timing of electromagnetic brake operation be-
tween forward rotation (rise) and reverse rotation (fall) during vertical lift operation, etc. When Pr. 43
9999, the Pr. 42 setting is used for forward rotation and the Pr. 43 setting is used for reverse rotation.

NOTES The FU signal is assigned to the terminal FU in the initial setting. The FU signal can also be
assigned to the other terminal by setting "4 (positive logic) or 104 (negative logic)" in any of Pr. 190
to Pr. 192.
All signals are off during DC injection brake.
The output frequency to be compared with the set frequency is the output frequency before slip
compensation is performed.
Changing the terminal assignment using Pr. 190 to Pr. 192 "Output terminal function selection"
may affect the other functions. Make setting after confirming the function of each terminal.
