CP1/CP2 • Receive count signals.
• Receive increment, decrement, individual, and quadrature inputs.
• In increment mode and decrement mode, CP1 is used for the count input and CP2 is used
for count prohibit input.
Reset • Resets the present value. (Totalizing count value is not reset.)
(In increment mode or increment/decrement mode, the present value returns to 0; in Decre-
ment Mode the present value returns to the set value.)
• The count input is not received during resetting.
• The RST indicator is lit during resetting.
