Application of EP3E-PN in the Energy Measurement Industry

Smart meters are essential energy metering products for every household, including the replacement of existing markets and the addition of new properties. The demand for smart meters is increasing day by day. EP3E-PN is applied in automatic production lines and has great advantages in fastening anti-theft screws. Fast and precise torque control are its most important features.

2、 System solution
Siemens PLC 1200 series+2 sets of PN servo, dual station design
EP3E-PN servo, message selection 111+750 auxiliary message
technological requirements
The mechanical shaft moves up and down and completes the locking screw without damaging the appearance of the product, achieving the design torque and completing it within the beat time.

3、 Advantages of the plan
The 111 message does not require configuring the process axis, saving PLC resources. The position loop is on the servo side, and the operation response is fast. It can control the use of multiple axes
750 message real-time data transmission, precise control of torque output, screws reaching the theoretical design tightening torque without damaging the appearance of the workpiece product
To complete the locking and anti-theft hole orientation, the same effect requires 2 manual workers and takes a long time to complete
