Low speed operation
l
Check if motor speed is +10.0 rpm in the start-up LCD screen after pressing [FWD] key.

If A and B phase are reversed, be sure to replace A with B phase wire after checking the pulse encoder wiring.
Or user does not need to change wiring if PAR_11(Enc Dir Set) setting value is changed from “A Phase Lead”
to “B Phase Lead”.

Change the value of FUN_12 to 1000.0(rpm) and Check the display LCD by pressing [FWD], [REV] keys shown
below.
