3.3 I/O Signals to the CPU Module 3.3.3 Details on output signals
• The following input signals turn off by turning on this signal. (This is also applied to CH2.)
• To check the timing of turning on and off this signal, refer to the following:
Page 34, Section 3.3.2 (2)
(2) CH1 Coincidence output enable command (Y02)
• When the coincidence output function or the cam switch function is used, turn on this signal to output signals
from the coincidence output 1 to 8 terminals (EQU1 to EQU8).
• This signal works on any coincidence output 1 to 8 terminals (EQU1 to EQU8) that are assigned to the
corresponding channel.
(3) CH1 Preset/replace command (Y03)
• Turn on this signal to replace a count value with the preset value.
• The value cannot be replaced by this signal while CH1 External preset/replace (Z Phase) request detection
(X05) is ON. Turn off CH1 External preset/replace (Z Phase) request detection (X05) by using CH1 External
preset/replace (Z Phase) request detection reset command (Y05).
(4) CH1 Count down command (Y04)
• Turn on this signal to count down pulses.
• This signal is enabled when the 1 multiple of 1 phase or the 2 multiples of 1 phase is selected for the pulse
input mode.
• Inputting pulse in phase B can also start counting down pulses.
• The count is done as below in 1 multiple of 1 phase.
