AXY:MC-Basic:axis.ACCELERATION
This property sets the acceleration rate of the motion profile. When executing a motion command, acceleration should be less than or equal to ACCELERATIONMAX. If it is greater, the motion is executed using the ACCELERATIONMAX value.
This property can be used inside a motion command to override the permanent value.
Short form

Syntax
<axis>.Acceleration = <expression >

Type
Double
Range
Greater than 0
Units
User axis acceleration units, as given by <axis>.ACCELERATIONFACTOR.
Default
1000
Scope
Configuration, Task or Terminal
Limitations
The ratio between jerk and acceleration is limited by the following relation:
Jerk/Acc < 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 axis must be attached to that task (using the ATTACH command).
Examples
Xaxis.acceleration = 1e10
Move Xaxis 100 acc = 2e10
