Basic Information
Section 6-1
Commands using the
Counter Latch Function The following six commands use the counter latch function:
With variables in the following table, whether or not the counter latch has been
completed can be confirmed:
Counter latch positions are stored in each variable shown in the following
table:
Latch signals used for counter latch can be set in the following parameters:
Command Purpose for using
counter latch function
Role of latch signal
DATUM: Origin search Detects origin The trigger to decide the final
stop position
MOVEI: Interrupt feeding Detects external signal
input position The trigger to decide the final
stop position
MOVELINK: Link opera-
tion Detects link start position The trigger to start synchroni-
zation
CAMBOX: Electronic
Cam, Synchronous Detects link start position The trigger to start synchroni-
zation
SYNC: Trailing Synchro-
nization Detects position of
marker sensor ON. The trigger to start synchroni-
zation
LATCH: Present position
latch Detects latch position The trigger to store the latch
position
