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.
Active only when VelocitySettings is set to 0. When VelocitySettings is set to 1, ASCALE is used.
Short form
<element>.Acc
Syntax
<element>.Acceleration = <expression >
?<element>.Acceleration
Availability
All versions
Type
Double
Range
Greater than 0
Units
User element acceleration units, as given by <element>.ACCELERATIONFACTOR
Default
Group = 500
Axis = 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 element must be attached to that task (using the ATTACH command).
Examples
Axis
A1.acceleration = 1e10
Move A1 100 acc = 2e10
Group
G1.acceleration = 1e10
Move G1 (100, 200) acc = 2e10
