Status
Description
Positioning The axis executes a positioning task of motion control instruction "MC_MoveAbsolute" or
"MC_MoveRelative" or of the control panel.
(Tag of technology object: <Axis name>.StatusBits.PositioningCommand)
Speed Command The axis executes a task at set speed of motion control instruction "MC_MoveVelocity" or
"MC_MoveJog" or of the control panel.
(Tag of technology object: <Axis name>.StatusBits.SpeedCommand)
Homing The axis executes a homing task of motion control instruction "MC_Home" or the control
panel.
(Tag of technology object: <Axis name>.StatusBits.Homing)
