Weg CFW500F77P0T4DB20G2 VFD 77.0 Amp 50-60 HP 460 VAC 3-phase
The CFW500 series AC Drive for electric motors is a compact, cost-effective VFD for a variety of applications such as pumps, process control, extruders, general machinery and more. A wide variety of options include SoftPLC programming, USB, RS-232 & RS-485, CANopen, Profibus, Modbus, Ethernet IP and more. Available in IP20 and NEMA 1 Enclosures (NEMA 1 special order). The IP20 is DIN rail mountable.
The CFW500 series has built-in softPLC support for custom programming. This can often eliminate the need for an external PLC.
Caldwell Electric can setup VFD parameters and develop custom PLC programs to fit your needs for a nominal fee.

A Note on HP: It is best to match a VFD drive to the motor based on nameplate current, rather than HP. This is because the drive power electronics are rated by current. To ensure the drive can handle the motor nameplate current, the drive's current should be at least as high as the full load amps of the motor, and better if allowing is made for the service factor as well. So for example, a motor with nampelate current of 10 amps, with a S.F. rating of 1.15 could draw up to 11.5 Amps. Choose a VFD with a current rating of 11.5 or more.
