RESET
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 鈥淓ffective during incrementing and decrementing a
count鈥?or to 鈥淓ffective only during incrementing a count.鈥?/div>
Note:
External compensation input minimum signal width: 16 ms
