[Also in Division H3] An improved circuit (see Division H3) for controlling an inductive load may be employed to control an electromagnetic brake. Fig. 5 shows a position control system including an electromagnetic coupling 39 and a brake 40. Each cycle is initiated by a signal from a photoresistor 43 which is amplified at 45 and triggers a monostable circuit 46, the pulse from which sets a bi-stable circuit 47 so as to trigger thyristor 41 and energize the magnetic coupling 39. When the traverse reaches a position indicator 48, a monostable circuit 50 is triggered which resets the bi-stable circuit 47 which turns off thyristor 41 and, via an inverter 51, triggers thristor 42 and applies electromagnetic brake 40. Fig. 8 shows a circuit for energizing one of magnetic couplings 52, 70 or a brake 53 by energizing the appropriate thyristor or transistor 54, 55 or 73. When one of devices 54, 55, 73 is opened, the magnetic energy in the associated winding is dissipated in the form of current flowing via one of diodes 56, 57, 74 or 75 to one of capacitors 58, 76. Alternatively, if one of switches 71, 76 is closed, the magnetic energy is dissipated by energizing one of the other magnetic devices. Each diode 56, 57 is shunted by a series arrangement of resistance and opposing diode so as to discharge the capacitor.
