A work head unit that detects the rotational position of suction nozzle with first Q-axis encoder positioned facing component holding section that holds a component. With the work head unit, it is desirable to detect the orientation of component holding section at two locations: suction nozzle and syringe member.

Systems and methods for operating a motorized system. The methods comprise by a circuit: receiving a first position signal generated by a gimbal resolver coupled to a load, a second position signal generated by a first motor encoder coupled to a shaft of a first motor, and a third position signal generated by a second motor encoder coupled to a shaft of a second motor; converting the second and third position signals into a velocity signal specifying a scaled velocity of the load; converting the velocity signal into a fourth position signal specifying a position of the load; combining the first position signal and the fourth position signal to generate a fifth position signal representing a stable position of the load; and using the fifth position signal to control operations of the first and second motors.

A device for processing rotation-dependent measured values includes a data converter, a sequencing control, and an output interface. Series of measured values, which are a function of the rotation of a shaft and of which at least one is an angle value that indicates the angular position of the shaft, are conveyable to the data converter at constant time intervals of a measuring interval. The data converter is adapted to subdivide a rotation of the shaft into sectors and, using one of the angle values as a reference angle value, to allocate received measured values to a sector, and per rotation of the shaft, to ascertain for each series of measured values precisely one result value for each sector. The result values are able to be output to the output interface.
