Unidrive M100 User Guide 125
Issue Number: 1
EEF Default parameters have been loaded
31
The EEF trip indicates that default parameters have been loaded. The exact cause/reason of the trip can be identified from
the sub-trip number.
Recommended actions:
• Default the drive and perform a reset
• Allow sufficient time to perform a save before the supply to the drive is removed
• If the trip persists - return drive to supplier
Et An External trip is initiated
6
An Et trip has occurred. The cause of the trip can be identified from the sub trip number displayed after the trip string. See
table below. An external trip can also be initiated by writing a value of 6 in Pr 10.038.
Recommended actions:
• Check the value of Pr 10.032.
• Select ‘Dest’ (or enter 12001) in Pr mm.000 and check for a parameter controlling Pr 10.032.
FAN.F Fan fail
233
Recommended actions:
• Check that the fan is installed and connected correctly.
• Check that the fan is not obstructed.
• Contact the supplier of the drive to replace the fan.
Fi.Ch File changed
247
Recommended action:
• Power cycle the drive.
FI.In Firmware Incompatibility
237 The FI.In trip indicates that the user firmware is incompatible with the power firmware.
HF01 Data processing error: CPU hardware fault
The HF01 trip indicates that a CPU address error has occurred. This trip indicates that the control PCB on the drive has
failed.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
HF02 Data processing error: CPU memory management fault
The HF02 trip indicates that a DMAC address error has occurred. This trip indicates that the control PCB on the drive has
failed.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
HF03 Data processing error: CPU has detected a bus fault
The HF03 trip indicates that a bus fault has occurred. This trip indicates that the control PCB on the drive has failed.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
HF04 Data processing error: CPU has detected a usage fault
The HF04 trip indicates that a usage fault has occurred.This trip indicates that the control PCB on the drive has failed.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
Trip Diagnosis
Sub-trip Reason
1 The most significant digit of the internal parameter database version number has changed
2
The CRC's applied to the parameter data stored in internal non-volatile memory indicate that a valid set
of parameters cannot be loaded
3
The drive mode restored from internal non-volatile memory is outside the allowed range for the product
or the derivative image does not allow the previous drive mode
4 The drive derivative image has changed
5 The power stage hardware has changed
6 The internal I/O hardware has changed
7 Reserved
8 The control board hardware has changed
9 The checksum on the non-parameter area of the EEPROM has failed
Sub-trip Reason
1 External Trip (10.032) = 1
