J INTERVAL TIMER INTERRUPTS
The CPM1A has one interval timer. The interval timer shuts down the regular program regardless of the point in the cycle once the time is
up, and immediately executes an interrupt processing program. Interval timers are used in the following two modes.
J ANALOG SETTING
The CPM1A contains two analog setting controls that can be used for a broad range of analog timer and counter settings. Turning the
setting control stores values of 0 to 200 (BCD data) in the SR area.
*Phillips screwdriver is required
to turn analog adjustment knobs.

Application Example:
Tact Operation Control of Conveyor Lines
A conveyor can be stopped temporarily as required for assembly
processes. When the timer function and limit switches are used
in a combination, conveyors can be stopped for a fixed time or
can be run at a constant speed for a fixed distance. Fine
adjustment of the stopping time can be easily done by using the
analog setting controls.
Scheduled interrupt mode
Interrupts are executed repeatedly at fixed periods.

Application Example:
Computing the Sheet Speed
The number of pulse inputs is computed
in the interrupt mode at a fixed time to
calculate the speed.
