(6) [Pr.6] Rotation direction setting
Set the relation of the positioning direction ([Md.20] Current feed value increment direction/decrement direction)
and the pulse output. For the relation of "Forward run pulse output, Reverse run pulse output" and "CW/A
phase/PULSE signal, CCW/B phase/SIGN signal", refer to "[Pr.5] Pulse output mode".
Ex.
The following figure shows the pulse outputs of when "[Pr.5] Pulse output mode" is set to CW/CCW mode
and the positioning with current feed value (increment direction)/(decrement direction) is executed.
When [Pr.6] has been changed from "0" to "1", check if the upper/lower limit switches operate properly by JOG operation. If
any malfunction is identified, check and correct the wiring.
