5.13.9 Output stop function
The motor coasts to a stop (inverter output is shutoff) when the inverter output frequency falls to Pr.522 setting or lower.

Output stop frequency
G105
• When both of the frequency setting signal and output frequency fall to the frequency set in Pr.522 or lower, the inverter
stops the output and the motor coasts to a stop.
• The motor re-starts when the frequency setting signal exceeds Pr.522 + 2 Hz and is accelerated at the Pr.13 Starting
frequency (0.01 Hz under PM motor control).

The output frequency to be compared with the Pr.522 setting is the output frequency before slip compensation (V/F control or Advanced
magnetic flux vector control), or the speed command value converted into the frequency (PM motor control).
The motor is accelerated at the Pr.13 Starting frequency (0.01 Hz under PM motor control).
The steepness of the slope depends on the acceleration/deceleration time settings such as Pr.7.
