Issue:
ATV630 and ATV930 causes with an bOF or brake resistor overload fault.

Product Line:
ATV630 and ATV930 Process drives

Environment:
All

Cause:
Parameter setting of the braking resistor not correct (brtC, brV, brP)

Resolution:

Principle: The thermal model of the braking resistor has detected and overload.The themal state of the BR can be monitored with the parameter tHb. Probable cause: - parameter setting of the braking resistor not correct (brtC, brV, brP) Remedies: - check the nominal power of the braking resistor. - verify the BR parameters brP, brV, brtC - check with SoMove service section the thermal states TH1R / TH2R / TH3R - check the thermal state parameter tHb [Braking Resistor monitoring]
