Motor brake and stop operation
With brake opening completion signal input (Pr. 292 = 8)
● When the start signal is input to the inverter, the inverter starts running. When the internal speed
command reaches the value set in Pr. 278 and the output current is not less than the value set in
Pr. 279, the inverter outputs the brake opening request signal (BOF) after the time set in Pr. 280
has elapsed.
When the time set in Pr. 281 elapses after the BOF signal is output, the inverter increases the output
frequency to the set speed.
● When the inverter decelerates to the frequency set in Pr. 282 during deceleration, the inverter
turns OFF the BOF signal 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. And after
the time set in Pr. 283 passes, the inverter decelerates again. The inverter finally stops when its
frequency reaches to Pr. 13 "Starting frequency setting" or 0.5 Hz, whichever is lower.

NOTE If brake sequence mode has been selected, inputting the jog signal (jog operation) or RT signal
(second function selection) during an inverter stop will make brake sequence mode invalid and
give priority to jog operation or second function selection. Note that JOG and RT signal input is
invalid even if JOG signal and RT signal are input during operation in brake sequence mode.
