Issue Number: 1
P. dA t Power system configuration data error
220
The P. dA t trip indicates that there is an error in the configuration data stored in the power system. This trip is generated
from within the drive control system or from the power system. The trip is related to the table uploaded from the power
system at power-up.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
Pb.bt Power board is in bootloader mode
245
Power board is in bootloader mode
Recommended actions:
• Contact the supplier of the drive.
Pb.Er Communication has been lost / errors detected between control and power processor
93
The Pb.Er trip is initiated if there is no communications between the control board processor and the power board
processor. The reason for the trip can be identified by the sub-trip number.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
Pb.HF Power board HF
235
Power processor hardware fault. The sub-trip number is the HF code.
Recommended actions:
• Hardware fault - Contact the supplier of the drive
Pd.S Power down save error
37
The Pd.S trip indicates that an error has been detected in the power down save parameters saved in non-volatile memory.
Recommended actions:
• Perform a 1001 save in Pr mm.000 to ensure that the trip doesn’t occur the next time the drive is powered up.
