6.1.5. The DAQ_Move Class¶

This documentation highlights the useful entry and output points that you may use in your applications.

class pymodaq.control_modules.daq_move.DAQ_Move(parent=None, title='DAQ Move')[source]¶

Main PyMoDAQ class to drive actuators

Qt object and generic UI to drive actuators.

init_signal¶

This signal is emitted when the chosen actuator is correctly initialized

move_done_signal¶

This signal is emitted when the chosen actuator finished its action. It gives the actuator’s name and current value

bounds_signal¶

This signal is emitted when the actuator reached defined limited boundaries.

Attributes

actuator: str: the selected actuator’s type
initialized_state: bool: status of the actuator’s initialization (init or not)
move_done_bool: bool: status of the actuator’s action (done or not)

Methods

`get_actuator_value`()	Get the current actuator value via the "get_actuator_value" command send to the hardware
`get_continuous_actuator_value`([get_value])	Start the continuous getting of the actuator's value
`grab`()	Programmatic entry to grab data from detectors or current value from actuator
`init_hardware_ui`([do_init])	Programmatic actuator's Initialization
`move`(move_command)	Generic method to trigger the correct action on the actuator
`move_abs`(value[, send_to_tcpip])	Move the connected hardware to the absolute value
`move_home`([send_to_tcpip])	Move the connected actuator to its home value (if any)
`move_rel`(rel_value[, send_to_tcpip])	Move the connected hardware to the relative value
`quit_fun`()	Programmatic quitting of the current instance of DAQ_Move
`stop_motion`()	Stop any motion

get_actuator_value()[source]¶

Get the current actuator value via the “get_actuator_value” command send to the hardware

Returns nothing but the move_done_signal will be send once the action is done

get_continuous_actuator_value(get_value=True)[source]¶

Start the continuous getting of the actuator’s value

Parameters: get_value (bool) – if True start the timer to periodically fetch the actuator’s value, else stop it

Notes

The current timer period is set by the refresh value ‘refresh_timeout’ in the actuator main settings.

grab()[source]¶: Programmatic entry to grab data from detectors or current value from actuator

init_hardware_ui(do_init=True)[source]¶

Programmatic actuator’s Initialization

Programmatic way to simulate a click on the init button of the UI to initialize the communication with the hardware

Parameters: do_init (bool) – if the init or des-init should be performed

move(move_command: MoveCommand)[source]¶

Generic method to trigger the correct action on the actuator

Parameters: move_command (MoveCommand) – MoveCommand with move_type attribute either: * ‘abs’: performs an absolute action * ‘rel’: performs a relative action * ‘home’: find the actuator’s home
