Output stop function
The motor coasts to a stop (inverter output shutoff) when inverter output frequency falls to Pr. 522
setting or lower.
● When both of the frequency setting signal and output frequency falls to the frequency set in
Pr. 522 or lower, the inverter stops the output and the motor coasts to a stop.
● At a stop condition, the motor starts running when the frequency setting signal exceeds Pr. 522
+ 2 Hz. The motor is accelerated at the Pr. 13 "Starting frequency" (0.01 Hz under PM sensorless
vector control) at the start.
* The output frequency before the slip compensation is compared with the Pr. 522 setting.
When the output stop function is valid (Pr. 522 ≠ "9999"), the DC injection brake (zero speed con-
trol, servo lock) becomes invalid and the motor coasts to stop when the output frequency drops to
the Pr. 522 setting or lower.
