powerflex700 Stop Assertd fault

Hi there

I have a Powerflex700 connected by devicenet to a control logix system. The drive is commanded by a SCADA but is not working.

In the HIM you can see the drive is in Stop Assertd (parameter 214)

Anybody have an idea of what this can be? Or what parameters should I check?

The stop command can come from multiple sources. A command over DeviceNet, a HIM module on the drive, a hardwired circuit to one of the digital inputs on the drive are just a few possibilities.

If you just installed a new drive as a replacement, my money would be on the digital inputs. Off the shelf, they are configured for 3-wire control from the digital inputs. No signal on the stop input = "stop asserted".

If that doesn't help, more info about your system would allow more detailed help.

Please check par 214 and tell us what is inside. Also check for enable jumper between terminals 2 and 16.
