is the assignment of the coincidence output 1o
to 8 proper?
Review "Coincidence output (1 to 8) channel assignment setting" in the switch
setting.

function
Is the comparison condition for coincidence
output 1 to 8 proper?
Review the setting of Coincidence output condition setting (Un\G0).
After changing Point setting (coincidence
output 1 to 8) (Un\G100 to Un\G115) or Upper/
lower limit values (coincidence output 1 to 8)
(Un\G120 to Un\G151), has Operating
condition settings batch-change command
(Y01) been turned on, or has Setting change
request (coincidence output 1 to 8) (Un\G180
to Un\G187) been set to Requested (1
H
)?
After changing Point setting (coincidence output 1 to 8) (Un\G100 to Un\G115)
or Upper/lower limit values (coincidence output 1 to 8) (Un\G120 to Un\G151),
turn on Operating condition settings batch-change command (Y01), or set
Setting change request (coincidence output 1 to 8) (Un\G180 to
Un\G187)been to Requested (1
H
).
Has Reset command (coincidence output 1 to
8) (Y10 to Y17) been turned on? (only when
Coincidence output condition setting (Un\G0)
is coincidence output (0))
Turn off Reset command (coincidence output 1 to 8) (Y10 to Y17).
Have Point setting (coincidence output 1 to 8)
(Un\G100 to Un\G115) and Upper/lower limit
values (coincidence output 1 to 8) (Un\G120 to
Un\G151) been set outside the count range of
the ring counter when the counter format is the
ring counter?
Set Point setting (coincidence output 1 to 8) (Un\G100 to Un\G115) and
Upper/lower limit values (coincidence output 1 to 8) (Un\G120 to Un\G151)
within the count range of the ring counter.
Cam
switch
function
At the step setting, is the minimum setting
width of the ON/OFF status proper?
Review the minimum setting width of the ON/OFF status referring to the
section on the cam switch function. ( Page 118, Section 4.3.4)
Have the steps been set outside the count
range of the ring counter when the counter
format is the ring counter?
Review the step setting and set steps within the count range of the ring
counter.

condition setting (Un\G0) is coincidence output
(0))
Set the ON time of Reset command (coincidence output 1 to 8) (Y10 to Y17)
2ms or longer.
