Chuck control units convert the AC (alternating current) input from the power line into DC (direct current) output to “feed” the coils of the chuck.
A microprocessor based control board in the unit allows adjusting the clamping force of the magnet and also automatic demagnetization. An important function lies in operator safety: The chuck control prevents the machine from running if the holding force of the chuck is too low.
The holding force can be adjusted by a rotary button on the remote control station which controls the output voltage.
A lower output voltage also helps to reduce the warming up of the coils inside the chuck in order to work cooler and obtain a higher accuracy.
Both the magnetic chuck and the workpieces can be completely demagnetized.
Depending on the type of steel, different demagnetizing programs can be selected.
For electromagnetic chucks we offer 2 types of control units M and MT (with transformer) and in 2 versions:
1 protection class IP00 for integration in the machine’s control cabinet
2 built into steel enclosure, protection class IP54
Standard output voltage: 110 VDC
Input voltage: 230 VAC
Choosing the correct control unit depends upon the magnet wattage or the total wattage of multiple magnets.
