Change Decel DINT
Immediate
If you want to Then Choose
Use the Maximum
Deceleration rate of
the axis.
No = 0
Specify the
deceleration rate.
Yes = 1
Decel Rate REAL
Immediate or
Tag
Important: The axis could overshoot its target
position if you reduce the deceleration while a
move is in process.
Deceleration rate of the axis. The instruction uses
this value only if Change Decel is Yes.
Decel Units DINT
Immediate Which units do you want to use for the Decel Rate?
• Units per sec
2
(0)
• % of Maximum (1)
Change Decel
Jerk
DINT
Immediate
If you want to Then Choose
Use the Maximum
Deceleration Jerk
rate of the axis.
No (0)
Program the
deceleration jerk
rate.
Yes (1)
Decel Jerk REAL
Immediate or
Tag
Important: The axis could overshoot its target
position if you reduce the deceleration jerk while a
move is in process.
You must always enter a value for the Decel Jerk
operand. This instruction only uses the value if the
Profile is configured as S-curve.
Decel Jerk is the deceleration jerk rate of the axis.
Use these values to get started.
Decel Jerk = 100 (% of Time)
0 = Units per sec
3
1 = % of Maximum
2 = % of Time (use this value to get started)
Jerk Units DINT

When the MAS instruction is used to with either an All or
DirectVelocityControlStatus Command Stop Type, the selection also clears the
MDS In Process (.IP) bit, and clears the Axis DirectVelocityControlStatus bit in
the Motion Status attribute
