OFF: Stops counter operation. The
high-speed counter PV is held.
ON: Starts counter operation. The
high-speed counter PV is not reset.
OFF: If the counter reset method is
set to a software reset in the Unit
Setup Area (DM 6605 and DM
6607), the high-speed counter PV is
not cleared when internal I/O refresh
is performed in the Customizable
Counter Unit. If the counter reset
method is set to a phase Z + soft-
ware reset, phase-Z input is dis-
abled.
ON: If the counter reset method is
set to a software reset in the Unit
Setup Area (DM 6605 and DM
6607), the high-speed counter PV is
cleared when internal I/O refresh is
performed in the Customizable
Counter Unit. If the counter reset
method is set to a phase Z + soft-
ware reset, phase-Z input is
enabled.
OFF: Measurement for high-speed
counter rate of change or frequency
measurement is disabled.
ON: Starts measurement for high-
speed counter rate of change or fre-
