5 DriveProgramming User Variables
5 - 10
DriveProgramming User’s Manual (I622-E1)
5-3 Timer Variables
This section describes the timer variables provided for the DriveProgramming's timer control commands.
These are the timer counter variables and the timer output contacts used in the timer control com-
mands of the DriveProgramming.
When the timer output contact is specified in the timer control command “delay on/off” or “timer set”, the
timer counter variable corresponding to the specified contact starts counting. When the counter
reaches the specified value, the timer output contact is turned ON.
• The timer output contacts TD(0) to TD(15) are bit-size variables. This variable is read-only.
• When the program is started, the values of the timer output contacts TD(0) to TD(15) are cleared to
zero.
• The timer output contacts TD(0) to TD(15) start their operation after they are specified in the “delay
on/off” command or the “timer set” command. TD(0) to TD(15) are set to 0 (OFF) when the corre-
sponding timer counter variables are cleared to zero. When the timer counter variable reaches the
specified value, the contact is set to "1" (ON) and the status is retained. If the “timer off” command is
executed, the status of TD(0) to TD(15) are cleared to zero.
• The timer output contact (word access) TDw is a function to use the timer output contacts TD(0) to
TD(15) as a word-size variable. This variable is read-only.
• The timer output contacts TD(0) to TD(15) are set in the lower byte. Zero is read out for upper byte
data.
Precautions for Correct Use
If the DriveProgramming program is stopped, the data of the timer counter variables and the
timer output contacts is not retained but cleared to zero.
