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