Moving an axis with constant velocity / speed
Proceed as follows to move an axis with constant velocity / speed:
1. Check the requirements indicated above.
2. At the parameter "Velocity", specify the velocity / speed, with which the axis should be
3. Start the "MC_MoveVelocity" job with a positive edge at the parameter "Execute".
The current motion state is indicated in "Busy", "InVelocity" and "Error".
If the "InVelocity" parameter shows the value TRUE, then the setpoint velocity / setpoint
speed was reached. The axis continues moving at this constant velocity. The parameters
"InVelocity" and "Busy" show the value TRUE, until the "MC_MoveVelocity" job is overridden
by another Motion Control job.
Note
Behavior when changing the override
If the velocity / speed is influenced during constant motion by a change in the override
(<TO>.Override.Velocity), then the "InVelocity" parameter is reset during the acceleration or
deceleration. When the newly calculated velocity / speed is reached ("Velocity" × "Override"
%), then "InVelocity" is reset.
Additional information
An option for the evaluation of the individual status bits can be found in the Evaluating
StatusWord, ErrorWord and WarningWord (Page 175) section.
