Plug-and-Play accessories add functionality and speed setup

Add communications option cards, I/O option cards, an FRI filter, and more — it all just snaps together. The flash memory module lets you download a set of parameters in seconds. And the remote keypad allows mounting outside the cabinet, close to the operator for easy access. There is even a snap-in replacement fan module — what could be easier?

Communicate with other factory devices

Use the RS-232 and RS485 communications option cards to communicate with other AC drives, PLCs, and other devices. Both cards also allow PC connectivity for programming, monitoring, and to upload and download drive parameters and the PLC program. The USB option module also allows configuration, programming and monitoring from your PC, along with upload and download of parameters sets and your PLC program.
