Frequency search of the FR-A800/FR-F800

What is the frequency search (reduced impact restart) that is performed when Pr.162 (Automatic restart after instantaneous power failure selection) is 3 or 13?
Category : 

Answer

DC voltage is applied when Pr.162 = 0, and AC voltage is applied when Pr.162 = 3 or 13. For the AC, the operation is easier to continue than the DC and the impact can be suppressed. Note that, for both V/F and Advanced magnetic flux vector control, tuning is required and the wiring length is 100 m or less.
