Issue Number: 3
CAM Advanced motion controller CAM failure
99
The CAM trip indicates that the advanced motion controller CAM has detected a problem.
Card Access NV Media Card Write fail
185
The Card Access trip indicates that the drive was unable to access the NV Media Card. If the trip occurs during the data
transfer to the card then the file being written may be corrupted. If the trip occurs when the data being transferred to the
drive then the data transfer may be incomplete. If a parameter file is transferred to the drive and this trip occurs during the
transfer, the parameters are not saved to non-volatile memory, and so the original parameters can be restored by powering
the drive down and up again.
Recommended actions:
• Check NV Media Card is installed / located correctly
• Replace the NV Media Card
Card Boot The Menu 0 parameter modification cannot be saved to the NV Media Card
177
Menu 0 changes are automatically saved on exiting edit mode.
The Card Boot trip will occur if a write to a Menu 0 parameter has been initiated via the keypad by exiting edit mode
and Pr 11.042 is set for auto or boot mode, but the necessary boot file has not been created on the NV Media Card to take
the new parameter value. This occurs when Pr 11.042 is changed to Auto (3) or Boot (4) mode, but the drive is not
subsequently reset.
Recommended actions:
• Ensure that Pr 11.042 is correctly set, and then reset the drive to create the necessary file on the NV Media Card
• Re-attempt the parameter write to the Menu 0 parameter
Card Busy NV Media Card cannot be accessed as it is being accessed by an option module
178
The Card Busy trip indicates that an attempt has been made to access a file on NV Media Card, but the NV Media Card is
already being accessed by an Option Module, such as one of the Applications modules. No data is transferred.
Recommended actions:
• Wait for the option module to finish accessing the NV Media Card and re-attempt the required function
Card Data Exists NV Media Card data location already contains data
179
The Card Data Exists trip indicates that an attempt has been made to store data on a NV Media Card in a data block which
already contains data.
Recommended actions:
• Erase the data in data location
• Write data to an alternative data location
Card Compare NV Media Card file/data is different to the one in the drive
188
A compare has been carried out between a file on the NV Media Card, a Card Compare trip is initiated if the parameters on
the NV Media Card are different to the drive.
Recommended actions:
•Set Pr mm.000 to 0 and reset the trip
• Check to ensure the correct data block on the
• NV Media Card has been used for the compare
Card Drive Mode NV Media Card parameter set not compatible with current drive mode
187
The Card Drive Mode trip is produced during a compare if the drive mode in the data block on the NV Media Card is
different from the current drive mode. This trip is also produced if an attempt is made to transfer parameters from a NV
Media Card to the drive if the operating mode in the data block is outside the allowed range of operating modes.
Recommended actions:
• Ensure the destination drive supports the drive operating mode in the parameter file.
• Clear the value in Pr mm.000 and reset the drive
• Ensure destination drive operating mode is the same as the source parameter file
Trip Diagnosis
Sub-trip Reason
1 CAM index or segment is out of range
2 AMC CAM Index (35.007) has been made to change by more than 2 in one sample
