Trane VFD error

[gbfromsd]

anyone know what error this is:

sysv.#09
exception error

has everyone here stumped.

is Trane using Toshiba drives? Looks an awful lot like a Toshiba to me.

Only drives I've ever seen with the Trane name on them were Danfoss TR1's. Try Danfoss's website and look-up literature for the TR1.

mallron is right, Danfoss unless it is in an older Voyager or Intellipac then it might be a Square D Altivar.

They use the Yasakawa drives for many things.

Yup Danfoss - exclusive rights since 2004 per Danfoss's website.
I did a bit of research last night and . . although not specific to this drive . . looks like an internal drive error caused by poor grounding??? I'll check this out but anyone with more specific info would be appreciated.
