Motion status
The following table shows the possible axis motion status values:
Status
Description
Done (no active job) No motion job is active at the technology object.
(<TO>.StatusWord.X6 (Done))
Homing job The technology object is executing a homing job from the Motion Control instruction
"MC_Home", or from the axis control panel.
(<TO>.StatusWord.X11 (HomingCommand))
Jog The axis is being moved by a jog mode job from the Motion Control instruction
"MC_MoveJog", or from the axis control panel.
(<TO>.StatusWord.X9 (JogCommand))
Velocity setpoint A job traverses the axis at the speed setpoint specified in Motion Control instruction
"MC_MoveVelocity" or at the axis control panel.
(<TO>.StatusWord.X10 (VelocityCommand))
Positioning job The axis is being moved by a positioning job from the Motion Control instructions
"MC_MoveAbsolute", "MC_MoveRelative", or from the axis control panel.
(<TO>.StatusWord.X8 (PositioningCommand))
Constant velocity The axis is traversing at a constant velocity or is at a standstill.
(<TO>.StatusWord.X12 (ConstantVelocity))
Standstill The axis is at a standstill.
(<TO>.StatusWord.X7 (StandStill))
Accelerating The axis is being accelerated.
(<TO>.StatusWord.X13 (Accelerating))
Decelerating The axis is being decelerated.
(<TO>.StatusWord.X14 (Decelerating))
