Interrupt Feeding
Section 9-5
Final Travel Distance for External Positioning
for W-series Servo Drives
(Pn814) is used for internal processing in the Position Control Unit when one
of the following origin search operation patterns are selected.
• When the origin detection method is set to any value except for 0 (Origin
proximity input signal reversal)
• When setting a zero point position offset for an origin search using an
absolute encoder
Because Pn814 is automatically overwritten by the Position Control Unit when
starting the origin search operation, if using the interrupt feeding after execut-
ing the origin search in the above operation pattern, be sure to set the
Exter-
nal Positioning Final Travel Distance
for G5-series Servo Drives (Pn820), the
Final Distance for External Input Positioning
for G-series Servo Drives
(Pn203) or
Final Travel Distance for External Positioning
for W-series Servo
Drives (Pn814) again.

Timing Chart for Interrupt Feeding
Interrupt feeding is executed by turning ON the INTERRUPT FEEDING Bit in
the Axis Operating Output Area and starting direct operation.
Timing Chart for Interrupt
Feeding Using
ABSOLUTE MOVEMENT
The following timing chart is for when INTERRUPT FEEDING is executed with
ABSOLUTE MOVEMENT. The timing chart for RELATIVE MOVEMENT is the
same, except that positioning is executed with the relative position if no inter-
rupt input signal is input.
