Abstract
In an electromagnetic operating system having a coil for electromagnetically controlling a mechanical operating member for operating the processing of objects in response to an alteration in an electrical voltage condition, the control system is arranged for generating test command pulses of different magnitude, for registering a command code in accordance with a smallest magnitude test command pulse causing the operating member to move, and for subsequently correcting alterations in the voltage condition for controlling the operating member in accordance with the registered command code. The control system is responsive for effecting the corrections in the alterations of the voltage condition in accordance with the registered command code. This enables simple correction for differences in the response delay among different electromagnetic operating systems.
