An adjustable-speed drive is used to control the motor speed and torque by varying motor input frequency and voltage. A variable-frequency drive (VFD) is used in KVAL machinery to accu- rately drive motors for machining or moving product through the machine. The figure below shows a block diagram of a typical motor drive circuit.
Figure 4- 25 on page 4- VFD models vary in KVAL machines depending on where it is used, voltage requirements and type of PLC used. This is a general view on the VFD. See the machine’s Electrical Print for detailed information.
Note: The number of reset buttons depends on the machine type and option. The fig- ure above shows a machine with 11 VFDs The VFD manuals are located in the Electrical Panels. On some machines, documentation can be found in the operation station in the documen- tation folder. KVAL Service Manual 4-11...
