Command Related Parameters
5.2.5 Position Data Latch Function Setting
This section describes the parameters for setting the position data latch function.
(1) Latching Allowable Area
Use the following parameters to set the range to input the latch signal for position data latching by
LTMOD_ON, LATCH, EX_POSING, or ZRET command. If the latch signal is input out of the set range, posi-
tion data will not be latched.
When Pn820 > Pn822
When Pn820 Pn822
(2) Continuous Latch Function
This function sequentially latches the input positions of sequence signal 1 to sequence signal n (n = 1 to 8) for
a specified number of times. The continuous latch operation can be aborted by executing the LTMOD_OFF
command. This function can shorten the time between latch completion and the start of the next latch, and
enables sequential latch operations at high speed.
