Input Specifications
The specifications depends on the input terminal numbers of the model. *1
*1. The following specifications apply to models with lot number 18321M (products produced in March 2021) or earlier.
*2. These values are the fixed response time needed by the hardware. A value from 0 to 32 ms (default: 1 ms) that is set on the Support Software
is added to these values.
*3. Set the filter time for every 4 points.
