Issue:
InFb fault possible causes without a brake resistor.
Product Line:
ATV61, ATV71, Altivar 61 Altivar 71
Environment:
All
Cause:
InFb fault - Internal th sensor
• The drive temperature sensor is not operating correctly
• The braking unit's temperature sensor is not operating correctly
Resolution:
For the InFb [Internal- th. sensor] fault, check the Drive Thermal State under menu 1.2 Monitoring (Drv. thermal state, tHd)
• Inspect/repair the drive
• Remove and inspect the control board
• Replace the braking unit's temperature sensor
• Inspect/repair the braking unit
• The monitoring of this fault must be deactivated by the [Brake res. fault Mgt] (bUb) parameter, if there is no braking unit connected to the drive
