Hi.

Just started to play with my new UCCNC setup and Nowforever VFD. Everything went well, motor was acting as expected but suddenly VFD runs like 10x less speed as commanded = S3000 = 50Hz is actually running only 5Hz. Any ideas what went wrong?
EDIT. Works now but no idea what was the reason....

Sact 870 => 2451 does not work either.
