Mitsubishi Electronics FR-F700-NA ユーザーズマニュアル

⋅ 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.

⋅ After a stop, the inverter output re-starts when the frequency signal is set higher than Pr.522 + 2Hz. The motor re-

accelerates at the Pr.13 Starting frequency.

* The output frequency before the slip compensation is compared with the Pr.522 setting.

*1 After a stop, inverter re-starts accelerating at Pr.13 Starting frequency.
*2 The output frequency before the slip compensation is compared with the Pr.522 setting.
*3 Steepness of the slope depends on the acceleration/deceleration time settings such as Pr.7.

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