Attributes:
| Name | Description |
|---|---|
| PositionScalar: DevDouble | — |
| UnitLimitMinScalar: DevDouble | — |
| UnitLimitMaxScalar: DevDouble | — |
| SlewRateScalar: DevDouble | Close loop velocity |
| AccelerationScalar: DevDouble | Close loop acceleration |
| ServoModeScalar: DevLong | 0 -> servo off (open-loop), 1 -> servo on (close-loop) |
| MotorReferencedScalar: DevLong | Indicates if motor is referenced. If not referenced (0) movement can not be performed. |
| HwLimitMaxScalar: DevDouble | Maximum position value set in the hardware. |
| HwLimitMinScalar: DevDouble | Minimum position value set in the hardware. |
| ConversionScalar: DevLong | pos = steps/conversion + unitcalibration |
| UnitCalibrationScalar: DevDouble | Offset to be added to the hardware position and software limits |
Commands:
| Name | Description |
|---|---|
| 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. |
| 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. |
| CalibrateInput: DevDouble Output: DevVoid |
Software calibration (using UnitCalibration) |
| StopMoveInput: DevVoid Output: DevVoid |
— |
| ReadClearErrorInput: DevVoid Output: DevLong Error code |
Read error and clear error status. |
| ReferenceMotorInput: DevVoid Output: DevVoid |
Performs a fast reference move to reference switch. If successful, absolute motion will afterwards be possible in closed-loop operation. |
| 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. |
