Input Modes and Present Value (See note 1.)

I/O Functions for Counter Operation

UP (Increment) Mode

DOWN (Decrement) Mode

CP1: Count input; CP2: Prohibit (gate) input

must be greater than the minimum signal width. (See note 2.)

CP1: Count input; CP2: Prohibit (gate) input

must be greater than the minimum signal width. (See note 2.)

CP1: Prohibit (gate) input; CP2: Count input

must be greater than the minimum signal width. (See note 2.)

CP1: Prohibit (gate) input; CP2: Count input

must be greater than the minimum signal width. (See note 2.)

* Counting starts when the CP1 is turned ON after turning ON the power.

UP/DOWN A Command Input Mode

UP/DOWN B Individual Input Mode

must be greater than the minimum signal width. (See note 2.)

UP/DOWN C Quadrature Input Mode

Note: 1. If the configuration selection is set to dual counter, CP1 and

CP2 input will operate in the same way as the count input

(CP1) of UP (increment) mode.

must be greater than the minimum signal width and

must be at least 1/2 the minimum signal width.

If they are less, a count error of

±1 may occur.

Minimum signal width: 16.7 ms (when maximum counting speed = 30 Hz)

100

µs (when maximum counting speed = 5 kHz)

3. The meaning of the H and L symbols in the tables is explained

below.
