Additional Information

Configurable Analog Output Provides More Functionality

Our PowerFlex® 523 drives now come with one configurable analog output. This new hardware capability is ideal for drives that are used in standalone applications. The analog output communicates a reference point to another drive or external device. This functionality provides customers with a simple and low-cost solution to monitor the machine. It creates additional actions without complicated configuration and hardware.

Firmware V3 is also released which contains additional features and functions to broaden the PowerFlex 523 drives capabilities. This firmware update supports:

  • Flux braking
  • Adjustable output phase loss sensitivity
  • Digital status bits
  • New EDS files

This firmware is backward compatible for all PowerFlex 523 drives, and the new analog output is only available in series B.
