8-10-5 Latching
Precautions for Correct Use
Limits on Latch Inputs
• A delay of up to 250 μs will occur between when the latch input is received and when the
latch data is processed. The latch data and latch completed flags will turn ON the first time
input data is refreshed after processing is completed.
Restrictions in Continuous Mode
• When you perform latching with an external input, a latch cannot be detected for 1 ms after
the previous latch was detected, even when the latch input is enabled.
Set the Latch Input 1 Motion Stop Enable or Latch Input 2 Motion Stop Enable variable to 1 to immedi-
ately stop pulse output when the corresponding latch is triggered.
After the latch is triggered and the output stops, the Latch Input 1 Enable or Latch Input 2 Enable bit is
set to disable the latch. Pulse output is then started when a command position is received.
Precautions for Correct Use
The response time from when the latch is triggered until the pulses are stopped is 250 μs max-
imum.
