Input type A <number> or A <L variable>
Terminology
<Number>: Set the number of variable for acceleration time.
0 ~ 9(Share the Dwell(E) Table used for a DWL command.)
<L variable>: Set the variable for an acceleration time from the L-VAR Table. (L0 ~ L999)

Parameter Maximum velocity(P18), acceleration or deceleration time(P23)
Explanation The acceleration time changes to a time(msec) set to the commanded variable number D or
L.
The acceleration value applied to a movement command is calculated in a time arriving
at the maximum velocity.
If commanding is omitted, then the Acceleration or deceleration time set to a parameter
“P23 Acceleration or deceleration time” is effective.
The once set acceleration time is effective until a reset unless it is reset.
Example of
use
A L0
A0
Designate an acceleration time by using a L0 variable.
Designate an acceleration time by using a D0 variable.
Example VEL 0
MOV P0
A0
MOV P1
Fig. 2.13 Acceleration time reset
Initial acceleration slope = Maximum velocity (P18) / Acceleration or deceleration time (P23)
Acceleration slope = Maximum velocity (P18) / D variable value or L variable value
