get_position(cache=True, propagate=1)

Returns the user position.

Parameters:

• cache (bool) – if True (default) return value in cache, otherwise read value from hardware

• propagate (int) – 0 for not propagating, 1 to propagate, 2 propagate with priority

Return type:

SardanaAttribute

Returns:

the user position

set_position(positions)

Moves the motor group to the specified user positions

Parameters:

positions (Sequence[float]) – the user positions to move to

Return type:

None

set_write_position(w_position, timestamp=None, propagate=1)

Sets a new write value for the user position.

Parameters:

• w_position (Sequence[float]) – the new write value for user position

• propagate (int) – 0 for not propagating, 1 to propagate, 2 propagate with priority

Return type:

None

property position: SardanaAttribute
