Classes

ALBAZoomMotor(name)

class mxcubecore.HardwareObjects.ALBA.ALBAZoomMotor.ALBAZoomMotor(name)[source]#

Bases: Device, AbstractMotor

get_limits()[source]#

Return actuator low and high limits.

Returns:

Two-item tuple (low limit, high limit).

Return type:

(tuple)

get_state()[source]#

Getter for state attribute.

Implementations must query the hardware directly, to ensure current results.

Returns:

Current state.

Return type:

HardwareObjectState

get_value()[source]#

Read the actuator position.

Returns:

Actuator position.

init()[source]#

Hardware object init.

is_ready()[source]#

Convenience function: Check if the object state is READY.

The same effect could be achieved with `python self.get_state() == self.STATES.READY `

Returns:

True if ready, otherwise False.

Return type:

bool
