Parameters
(a) Timer accuracy
The timer accuracy values, setting time range, and error are as
shown below.
Timer

number
The range of setting time (Note) Margin of error
8 msec 0 8 msec to about 262.1 sec 0 to ±1st level sweep interval (4/8 msec)
48 msec 1 48 msec to about 26.2 min 0 to ±1st level sweep interval (4/8 msec)
1 sec 2 1 sec to about 546 min 0 to ±1st level sweep interval (4/8 msec)
10 sec 3 10 sec to about 91 h 0 to ±1st level sweep interval (4/8 msec)
1 min 4 1 min to about 546 h 0 to ±1 sec
1 msec 5 1 msec to about 32.7 sec 0 to ±1st level sweep interval (4/8 msec)
10 msec 6 10 msec to about 327.7 sec 0 to ±1st level sweep interval (4/8 msec)
100 msec 7 100 msec to about 54.6 min 0 to ±1st level sweep interval (4/8 msec)
Error exclusively refers to that taking place while the timer
instruction carries out its operation. It does not include, for
example, error that occurs when the timer instruction is used in
the 2nd level sequence program, such as the delay from the
expiry of the timer until the sequence program initiates
processing (time equivalent to one cycle of the 2nd level at
worst).
NOTE
The value range of the setting time is between 0 and
32,767 for all timer accuracies. For example, when
the timer accuracy is 8 msec, the value 0 means 8
msec and the value 32,767 means 262,136 msec.
