Description
Electromagnet Chuck Control Units are designed to magnetize and demagnetize electromagnetic devices such as electromagnetic chucks and lifters. Magnetization consists of supplying a continuous DC output voltage to the device. Demagnetization cycles consist of a specific combination of positive and negative voltage pulse(s). The workpiece material may retain some residual magnetism due to its chemical and magnetic properties. The control units are designed to operate any 110VDC magnetic device within the specified wattage.
MPI’s Electromagnet Control Unit features an SR interlock safety contact. By using a potential free relay contact driven by the machine’s PLC, the controls can be enabled or disabled. The safety contact closes when the magnetic device is properly magnetized and should be used to enable the operation of the connected machine. A 24V signal on E-X3-10 of the control board provides a warning signal to disable the control unit. The safety control unit feature should be engaged during machining or transport.
