Spindle Machining Unit Maintenance

The spindle tool clamp/unclamp distance is monitored using an inductive analogue sensor with an operating voltage (0 - 10 V) from Pepperl + Fuchs. This analogue signal is then transferred to a Siemens ET200S Analog Electronic Module and converted into a digital value which is transferred to the PLC. The sensor is located on the top right of the rear of the spindle, and the ET200s Analog Electronic Module is located in the Electrical Cabinet.
