4.1 Pulse Input Mode and Counting Method 4.1.2 Counting method setting
(a) 1-phase pulse input
For 1-phase pulse input, multiple of 1 or multiple of 2 can be selected as a counting method.
The following figure shows the relationship between phase A pulse input, and phase B pulse input or the CH1
Count down command (Y04).
(b) CW/CCW pulse input
For CW/CCW pulse input, pulses can be counted up with the phase A pulse input and counted down with the
phase B pulse input .
The following figure shows the relationship between phase A pulse input and phase B pulse input.
(c) 2-phase pulse input
For 2-phase pulse input, a counting method can be selected from multiple of 1, multiple of 2, or multiple of 4.
The phase difference between phase A pulses and phase B pulses determines whether the pulses are counted
up or down.
The following figure shows the relationship between phase A pulse input and phase B pulse input.
4.1.2 Counting method setting
Configure a counting method in the switch setting.
For details on the setting method, refer to the following section.
