The control system is suitable for power supply and impulse control of electromagnetic and electro-permanent chucks. All functions are controlled by a powerful ARM Cortex-M4 microprocessor. The control system automatically adapts to the frequency of the power supply network. The magnetization level (output DC voltage) is continuously adjustable by potentiometer P1 on the control box. The output DC voltage is regulated from 5 to 95 % of the input AC voltage. The control system is equipped with efficient demagnetization cycles, which are designed to remove residual magnetism from workpieces, which can then be easily removed. To increase operator safety, the control system is equipped with a safety contact that indicates a break in the supply wire to the electromagnet and a low level of magnetization.
