(2) Operation example
• At start: 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 has elapsed after the brake opening completion signal (BRI) was input, the
inverter increases the internal speed command to the set speed.
• At stop: When the speed has decreased to the speed set in Pr. 282, the brake opening request signal (BOF) is
turned off. When the time set in Pr. 283 has elapsed after the brake operation confirmation signal (BRI)
was input, the inverter output is switched off.
*If Pr. 60 = "8" (mechanical brake opening completion signal not input), this time is the time after the
brake opening request signal is output.
