Interrupt Feeding Section 9-5
9-5-3 Data Settings for Using Interrupt Feeding
To execute interrupt feeding, the following parameters and data must be set in
addition to the parameters and data required for direct operation.

When using external latch signals 1 to 3, the external latch signal to be used
must be allocated in the Servo Drive's external input allocations.
When using a SMARTSTEP Junior Servo Drive, only 00 (phase Z) and 01
(external latch signal 1) can be used for the origin input signal selection.
Servo Parameter Area Interrupt Feeding Parameters
Set the travel distance from the position at which the interrupt input signal is
input. The travel direction for when the interrupt input signal is input is deter-
mined by the sign (positive or negative) in the set value. The operation per-
formed when the interrupt input signal is input depends on the sign for this
parameter and the sign of the position command value for direct operation, as
follows:
Note When using a Position Control Unit with unit version 2.0 or later, the Final Dis-
tance for External Input Positioning for G-series Servo Drives (Pn203) or Final
Travel Distance for External Positioning for W-series Servo Drives (Pn814) is
used for internal processing in the Position Control Unit for either of the follow-
ing origin search operation patterns.

Positive value Negative value
Positive value When the interrupt input sig-
nal is input, interrupt feeding
is executed in the same direc-
tion as the travel direction
when movement was started. When the interrupt input sig-
nal is input, interrupt feeding
is executed in the opposite
direction from the travel direc-
tion when movement was
started.
(Reversal mode operation)
Negative value When the interrupt input sig-
nal is input, interrupt feeding
is executed in the opposite
direction from the travel direc-
tion when movement was
started.
(Reversal mode operation) When the interrupt input sig-
nal is input, interrupt feeding
is executed in the same direc-
tion as the travel direction
when movement was started.
