Basic Information
Commands using the
Counter Latch Function
Commands
DATUM: Origin search
266
The following six commands use the counter latch function:
Command
DATUM: Origin search
MOVEI: Interrupt feeding Detects external signal
MOVELINK: Link opera-
tion
CAMBOX: Electronic
Cam, Synchronous
SYNC: Trailing Synchro-
nization
LATCH: Present position
latch
With variables in the following table, whether or not the counter latch has been
completed can be confirmed:
Variable
Output variables:
Axis status bits:
bit 10 [Counter latch
completed]
System variables:
SW022A + 30 ×
(Axis No. − 1)
Counter latch positions are stored in each variable shown in the following
table:

Remark
Relation to SW022A
0: SW022A = 0, 1, 2
1: SW022A = 3, 4
Only the latch signal input
during "latch being
requested" can be
accepted.
