While I haven't bought or used one yet either, I did go to a recent AB presentation on them and look forward to using one in my next application. Some of the features that impressed me are:
- The control module is common for all drive sizes.
- The control module and can be detached and then both powered-up and programmed via a USB cable connection. This should cut-down on both spare parts and start-up time.
- The control module has a built-in Ethernet port and can be expanded to have up to three (3) Ethernet ports. There are restrictions to how the three ports can be used, but if I understood correctly, all three ports are functional at the same time.
- The Safe-off feature is now built-in rather than available as an add-on option.
I know there are more features and improvements, but these are the ones that stuck out for me.
