Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.

In the wire and cable industry, many processes begin with pay-off and end with take-up wire. In the part of pay-off wire, how to control the uneven tension is the urgent difficulty for many equipment design engineers and products control engineers. In the past electric design, the engineers used to adopt the A/D, D/A module of PLC, using PCB with tension control technique, and gain the pay-off speed by read the potential of potentiometer with tension swing bar. In this method to maintain a constant tension, it usually adopts the signal line from potentiometer with the tension swing bar and analog signal line from the D/A module which control the speed of the variable frequency drive (VFD).
