Description and Selections
Set the I/O data update cycle of the Counter Func-
tion Module to correspond to either the high-speed
scan cycle or the low-speed scan cycle.
The first register address for the parameters is dis-
played. The first register address cannot be speci-
fied.
The signal form of the phase A and phase B
pulses. Always specify a +5 V differential input.
Set the polarity of the phase-A pulse signal and
phase-B pulse signal to positive logic or negative
logic.
Select one of the following seven pulse counting

methods .
• Signed with multiplier of 1
• Signed with multiplier of 2
• Up/down pulses with multiplier of 1
• Up/down pulses with multiplier of 2
• Pulses A/B with multiplier of 1
• Pulses A/B with multiplier of 2
• Pulses A/B with multiplier of 4
Always specify a reversible counter.
Specify whether to use coincidence detection
Specify whether to use coincidence interrupt
(This setting is valid only when coincidence detec-
tion is used.)
*3
Set the axis type to a finite-length axis or an
infinite length axis.
Specify the unit to use for references.
• pulse
• mm
• deg
• inch
If the reference unit is set to pulses, the electronic
gear will not be used. If any other option is
selected, the electronic gear is used.
