Interrupt Input Signal Selection
Select the interrupt input signal used for interrupt feeding.
00: Phase Z
01: External latch signal 1 input
02: External latch signal 2 input
03: External latch signal 3 input
Note (1) When 01, 02, or 03 (external latch signals 1 to 3) is selected in the origin
input signal selection/interrupt input signal selection, the external latch
signal to be used must be allocated in the Servo Drive's external input al-
locations. (Refer to
6-4 Standard Settings for Servo Drives Using
MECHATROLINK .)
(2) 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 selec-
tion and interrupt input signal selection. Do not select any other input sig-
nals.
Setting Example In this example, the origin search is performed using the Servomotor's phase
Z as the origin input, and external latch signal 2 as the interrupt input signal
for interrupt feeding.

Data Details Use there parameters to make the operation mode settings (origin search
operation mode) for each axis of the PCU. The bits specified as “0/00 (fixed)”
are reserved by the system in the PCU and must always be set to 0. For
details on settings, refer to
8-2-3 Data Settings Required for Origin Search ,
and 8-6-3 PCU Data Settings for Using Absolute Encoders .
Origin Search Operation
Select the origin search operation pattern. For details on operation patterns,
