DriveProgramming User’s Manual (I622-E1)
5-3 Timer Variables
5
These are the timer counter variables used in the timer control commands of the DriveProgramming.
The count data for the timer can be read.
When the variables are not used in the timer control commands, they are activated as the free running
counters.
• Timer counter TC (0) to TC (15) is unsigned 2 word variables.
• When the variables are not used in the timer control commands, they are activated as the free run-
ning counters that count up at 10 ms cycles at the same time of the start of a program of the Drive-
Programming.
• When the timer start command (timer set) and the delay command (delay on/off) are executed, the
timer counter variables are activated as a timer counter for the specified timer contact outputs. When
the commands are executed, the variables are cleared to zero. After a count up to the specified time,
it stops.
• When the timer stop command (timer off) is executed, the variables are cleared to zero.
Precautions for Correct Use
When a program of DriveProgramming stops, the timer counter variables and the timer output
contacts are not retained and the variables are cleared.
