Description
The axis travels at constant velocity.
(Tag of technology object: <Axis name>.StatusBits.ConstantVelocity)
The axis decelerates (slows down).
(Tag of technology object: <Axis name>.StatusBits.Deceleration)
Description
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)
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)
The axis executes a homing task of motion control instruction "MC_Home" or the control
panel.
(Tag of technology object: <Axis name>.StatusBits.Homing)
Description
The lower software limit switch has been reached.
(Tag of technology object: <Axis name>.ErrorBits.SwLimitMinReached)
The lower software limit switch has been exceeded.
(Tag of technology object: <Axis name>.ErrorBits.SwLimitMinExceeded)
The upper software limit switch has been reached.
(Tag of technology object: <Axis name>.ErrorBits.SwLimitMaxReached)
The upper software limit switch has been exceeded.
(Tag of technology object: <Axis name>.ErrorBits.SwLimitMaxExceeded)
The lower hardware limit switch has been approached.
(Tag of technology object: <Axis name>.ErrorBits.HwLimitMin)
The upper hardware limit switch has been approached.
(Tag of technology object: <Axis name>.ErrorBits.HwLimitMax)
A second axis is using the same PTO and is enabled with "MC_Power".
(Tag of technology object: <Axis name>.ErrorBits.HwUsed)
The "Axis" technology object was incorrectly configured or editable configuration data
were modified incorrectly during runtime of the user program.
(Tag of technology object: <Axis name>.ErrorBits.ConfigFault)
An internal error has occurred.
(Tag of technology object: <Axis name>.ErrorBits.SystemFault)
