Revision May 2009, BWE0, SW V1.05 5-79
When using a PG card with PG (encoder), speed search will begin at the actual PG (encoder)
feedback speed and settings 01 and 02 in Pr.08-04 will be invalid.

Current Limit for Speed Search
Unit: 1
Settings 30 to 200%
Factory Setting: 150
Following a momentary power loss, the AC motor drive will start its speed search operation
only if the output current is greater than the value set by Pr.8-07. When the output current is
less than the value of Pr.8-07, the AC motor drive output frequency is at “speed
synchronization point”. The drive will start to accelerate or decelerate back to the operating
frequency at which it was running prior to the power loss.

These parameters set the Skip Frequencies. It will cause the AC motor drive to never remain
within these frequency ranges with continuous frequency output.
