MOTORDRIVANORDNING FOR EN DEL I EN RONTGENAPPARAT |
摘要 |
The servo drive according to the invention includes a force transducer which is disposed so as to sense all the forces which act on the image-forming section (the weight of the section, the manual force of the user, frictional forces and acceleration forces). On the signal from the transducer there is superposed a signal which corresponds to the weight of said section and to the speed variations dn/dt, i.e., to the acceleration forces. Thus the influence of these forces on the output signal is compensated for. The resulting signal serves as the desired value for a speed or acceleration control. |
