•
The minimum interval between latch signals is 500 ms. An interval between latch signals that is
longer than the communication cycle is required to continuously obtain latched position data.
•
If two latch signals are input without allowing the minimum required interval, only the first latch
signal input position will be latched. The second latch signal will be ignored.
•
The parameters Pn850 to Pn853 can be changed only while the continuous latch operation is
stopped.
