Input type
D <number> or D <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 ~ L1999)

Parameter
Maximum velocity(P18), Acceleration or deceleration time(P23), deceleration time (P65)
Explanation
The deceleration time changes to a time(msec) set to the commanded variable number D or L.
The deceleration value applied to a movement command is calculated in a time arriving at 0 from
the “P18 maximum velocity”.
If commanding is omitted, then the deceleration time set to a parameter P23 or P65 is effective.
The once set deceleration time is effective until a reset unless it is reset.

Designate an deceleration time by using a L0 variable.
Designate an deceleration time by using a D0 variable.

Initial deceleration slope = Maximum velocity(P18) / Acceleration or deceleration time(P23)
Or, initial deceleration slope = Maximum velocity(P18)/Deceleration time(P65)
Deceleration slope = Maximum velocity(P18) / D variable value or L variable value.
