[ 7 ] Positioning control with pulse counter
J73 to J88
Positioning control parameters
This function allows simple positioning control with pulse counter and requires the PG interface card.
The inverter internally counts the feedback pulses and controls the motor so that the control object moves from the
previously specified start point, decelerates and switches to the creep speed operation to arrive at the specified
stop position.

0: Does not switch the direction of detected position
1: Switch the direction of detected position (Multiply by
“-1” the detected position)
— 0 N
*1 [P]: Current position (Absolute position) Switching between “0” and [P] requires the simultaneous keying: + keys
from “0” to [P] and + keys from [P] to “0.”
*2 In case of wrong wiring of the PG, inverts the position detection; direction, using J88 it is to possible correct the direction
without rewiring.
