Behavior with setpoint velocity / setpoint speed zero (Velocity" = 0.0)
An "MC_MoveJog" job with "Velocity" = 0.0 stops the axis with the configured deceleration.
When the setpoint velocity / setpoint speed zero is reached, the parameter "InVelocity" will
indicate the value TRUE.
Under "Technology object > Diagnostics > Status and error bits > Motion status", "constant
velocity" and "standstill" will be displayed (<TO>.StatusWord.X12 (ConstantVelocity);
<TO>.StatusWord.X7 (Standstill)).
Moving an axis in jog mode
Proceed as follows to move an axis in jog mode:
1. Check the requirements indicated above.
2. Move the axis in the positive direction with "JogForward", or in the negative direction with
The current motion state is indicated in "Busy", "InVelocity" and "Error".
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 is reached ("Velocity" × "Override" %), then
"InVelocity" is set again.
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.
