Attributes:

Name Description
PositionScalar: DevDouble move by PA, -2147483648 to +2147483647, relative to the position defined by the DH (Home) command, home is reset after power-up or system reset read-pos: TP?
UnitLimitMinScalar: DevDouble
UnitLimitMaxScalar: DevDouble
SlewRateScalar: DevDouble steps/sec, 1 - 20000, saved to non-volatile memory, with SM
AccelerationScalar: DevDouble steps/sec**2, 1 - 200000, saved to non-volatile memory, with SM
ConversionScalar: DevDouble pos = steps/conversion + unitCalibration
UnitCalibrationScalar: DevDouble pos = steps/conversion + unitCalibration
StepRegisterInternalScalar: DevDouble an internal step register which keeps track of the HW steps, used after power-up
StepRegisterControllerScalar: DevDouble displays the controller register

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.
StopMoveInput: DevVoid
Output: DevLong
completion status
stops the motion of an axis, uses acceleration to slow down
CalibrateInput: DevDouble
the new value of the current position
Output: DevLong
completion status
sets unitCalibration = pos - steps/conversion
ResetInput: DevVoid
Output: DevLong
completion status
This command performs a “soft” reset or reboot of the controller CPU. Upon restart the controller reloads parameters (e.g., velocity and acceleration) last saved in non-volatile memory and sets Home (DH) position to 0

Properties:

Name Description
CtrlDeviceDevString The name of the controller device
MotorChannelDevULong the channel no., 1 - 4
