Counts input signals.
Accepts Up/Down (individual or phase difference) inputs.
Resets the present value to zero.
No counting inputs are accepted when a RESET input is ON.
RESET is lit when a RESET input is ON.
Note: External reset minimum signal width: 16 ms
Resets the present counting value to the compensation value at the rising edge of a compensation input. In the
compensation value setting parameter, it is possible to set to "Effective during incrementing and decrementing a
count" or to "Effective only during incrementing a count."
Note: External compensation input minimum signal width: 16 ms
Selects one of the four banks.
