Pulse Input and Count Methods

Types of the pulse input method

There are six kinds of the pulse input methods: 1 phase pulse input (1 or 2 multiples), CW/
CCW pulse input, and 2 phases pulse input (1, 2 or 4 multiples). The pulse input methods
and count timing are shown in Table 5.1.
This chapter describes I/O numbers (X/Y) of channel 1 only.
For I/O numbers of channels 2 to 6 (X/Y), refer to Section 3.3.1.
The count method is set in the intelligent function module switch setting of GX Developer.
(Refer to Section 4.5.)
