Operation without brake opening completion signal input (Pr. 292 = "8")
●
When the start signal is input to the inverter, the inverter starts running, and when the output
frequency reaches the frequency set in Pr. 278 "Brake opening frequency" and the output current
or the motor torque is equal to or greater than the Pr. 279 "Brake opening current" setting, the
brake opening request signal (BOF) is output after the time set in Pr. 280 "Brake opening current
detection time".
After the BOF signal is output, the output frequency is increased to the set speed after the set time
in Pr. 281 "Brake operation time at start".
●
When the inverter decelerates to the frequency set to Pr. 282 "Brake operation frequency" during
deceleration, the inverter turns OFF the brake opening request signal (BOF) and decelerates
further to the frequency set in Pr. 278. After the turn OFF of BOF signal, the inverter holds the
frequency set in Pr. 278 for the time set in Pr. 283 "Brake operation time at stop". And after the set
time in Pr. 283 passes, the inverter decelerates again. Pr. 13 "Starting frequency" setting or 0.5 Hz,
whichever is lower

NOTE
Even if the brake sequence operation has been selected, inputting the JOG signal (JOG operation)
will change the operation method to normal operation and give a priority to the JOG operation.
Note that the JOG signal input by the brake sequence function is invalid during operation.
