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

Returns:

the user position

Return type:

SardanaAttribute

set_position(positions)

Moves the motor group to the specified user positions

Parameters:positions (sequence< Number >) – the user positions to move to

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

Sets a new write value for the user position.

Parameters:

• w_position (sequence< Number >) – the new write value for user position
• propagate (int) – 0 for not propagating, 1 to propagate, 2 propagate with priority
