This property sets the deceleration rate of the motion profile. When executing a motion command, DECELERATION should be less than or equal to DECELERATIONMAX. If it is greater, the motion is executed using the DECELERATIONMAX value. This property can be used inside a motion command to override the permanent value.
Short form
<group>.Dec
Syntax
<group>.Deceleration = <expression >
?<group>.Deceleration
Availability
All versions
Type
Double
Range
Greater than 0
Units
User group acceleration units, as given by <group>.ACCELERATIONFACTOR
Default
1000
Scope
Configuration, Task or Terminal
Limitations
The ratio between jerk and deceleration is limited by the following relation:
Jerk/Dec < 0.9 * p/5T
where T is the sample time in seconds. For a cycle time of 2 msec, this value is 282.74. Use SMOOTHFACTOR to have jerk calculated automatically. To set the value within a task, the group must be attached to that task (using the ATTACH command).
Examples
G1.deceleration = 1e10
Move Group1 {100, 200} dec = 2e10
