chattering to settle or longer in Position Data Determination Time (d238). To enable changes to the
positioning data with the RUN command ON, be sure to turn the position change command "POS-
SET" ON. As changes to the positioning data while the RUN command is OFF are reset when op-
eration is started, operation by position change command "POS-SET" is not required.
Orientation operation differs from position control in that, even when a value greater than one rota-
tion is set to positioning data, the value is automatically corrected to a position within one rotation
when the operation is actually performed.
To assign positioning data as an incremental amount of movement relative to the current position,
set movement in Positioning Data Type (d237). To switch handling when necessary, use increment/
absolute position switching "INC/ABS" (data = 135) in the multifunction input terminal function.
When this function is allocated, the d237 setting is disabled.
 Positioning Data Setting Selection via communication (d277)
In orientation, to use Positioning Data via Communication (MSB) (S20) and Positioning Data via
Communication (LSB) (S21) via communication to perform positioning, set "1" to Positioning Data
Setting Selection via communication (d277) to enable positioning commands via communication,
just as in position control.

Functions That Are Disabled in Position Control
When speed/position switching is set to "SPD" OFF and the RUN command is ON, the following func-
tions are disabled.
Jogging operation, PID control, starting frequency hold, stop frequency hold, DC braking, Zero Speed
Control, restart after momentary power failure, retry, offline tuning, anti-regenerative control, overload
prevention, Stop Selection (H11), pickup, torque control, 1st/2nd control.

Position Monitor
Use this function to monitor the feedback current position and instructed current position on the Digital
Operator. The feedback current position is the value obtained by totaling the number of feedback puls-
es and converting them to user values. The instructed current position is not the target position but the
momentary instructed position based on the position instruction pattern, and is the same as the feed-
back current position during a stop.
