5.13.4 High-speed Counter
1. Motion control function block
The motion control function block T_HCnt is used to start a high-speed counter. The value of the
Channel input pin indicates a counter, and the value of the InputType input pin indicates an input
pulse type. The ExtRstEN input pin is used to set an external reset switch. The value of the
InitialValue input pin is the initial value in the counter specified, and the value of the CountValue
output pin is the value in the counter specified.

The value of the ExtRstEN
input pin is valid when there
is a transition in the Enable
input pin's signal from low to
high.
When the motion control
function block is executed,
the value of the InputType
