AXY:MC-Basic:group.DECELERATION

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
