Marqim Posts: 13 Rating: (1)	Thanksfor answer, Graeme. I already knew about this diagram. It has disadvantage: it shows transitions between internal states of VFD, but there is no information, how VFD states are associated with status word bits. I suppose, the only way to clarify a behavior of VFD status word bits is experiment.

Start the drive with a setpoint, let it reach the setpoint, and then Stop the Drive whilst tracing (Use a recording interval of at least 15) and then afterwards, once the trace is finished, you can then change the Word view to individual Digital bits. You can then experiment with different OFF stop modes. Hope this helps Regards, Graeme

Best regards Whats the problem there? Status bits looking normal after Run command If you worried about changing from 4331 to 5334, then its natural due to change in some bits after drive run have a look at attached status word bits Regards Devesh Vithani Attachment SW1.pdf (440 Downloads)
