5.12.7 Instructing a Servo Drive to Capture Values
1. Motion control function block
The motion control function block T_DMCCapSet is used to instruct the servo drive specified on
a DMCNET to capture values. The value of the Axis input pin indicates an axis number. The
value of the CAP_Number input pin is the number of values which will be captured. Users can
set a capture signal by means of the Contact input pin, and set the source of the values which
will be captured. The value of the TriggerTime input pin indicates a minimum time interval, and
the value of the CapValue output pin is the value which is captured.
