Attributes:

Name Description
UnitCalibrationScalar: DevDouble Offset to be added to the hardware position and software limits
ConversionScalar: DevLong pos = steps/conversion + unitcalibration
HwLimitMinScalar: DevDouble Minimum position value set in the hardware.
HwLimitMaxScalar: DevDouble Maximum position value set in the hardware.
MotorReferencedScalar: DevLong Indicates if motor is referenced. If not referenced (0) movement can not be performed.
ServoModeScalar: DevLong 0 -> servo off (open-loop), 1 -> servo on (close-loop)
AccelerationScalar: DevDouble Close loop acceleration
SlewRateScalar: DevDouble Close loop velocity
UnitLimitMaxScalar: DevDouble
UnitLimitMinScalar: DevDouble
PositionScalar: DevDouble

Commands:

Name Description
StartStepAndMeasurementInput: DevDouble
Amplitude
Output: DevVoid
Starts performing a step and recording the step response for the given axis. A ``step`` consists of a relative move of the specified amplitude which is performed relative to the current position. The axis must not be referenced before a measurement is performed.
ReferenceMotorInput: DevVoid
Output: DevVoid
Performs a fast reference move to reference switch. If successful, absolute motion will afterwards be possible in closed-loop operation.
ReadClearErrorInput: DevVoid
Output: DevLong
Error code
Read error and clear error status.
StopMoveInput: DevVoid
Output: DevVoid
CalibrateInput: DevDouble
Output: DevVoid
Software calibration (using UnitCalibration)
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.
