Hi,
I have an ABB ACS355 (-01E-02A40-2) that I am trying to troubleshoot.
Giving the inverter power I get a flashing green power LED. I indent to use the Digital Inputs to control so I don't have a screen and am trying to connect using Drive Composer via USB-RS485, but it just says unable to connect.
When looking at the documentation, (page 374) mentions a green flashing LED as the 'Drive in an alarm state' but there are no further mentions about what could have caused it. No other mentions of 'alarm state' in the text actually.
I'm new to these so any help would be appreciated! even simple obvious things to check.
Thankyou
ash
