Unidrive M100 User Guide 123
Issue Number: 1
C.Pr NV Media Card data blocks are not compatible with the drive derivative
175
The C.Pr trip is initiated either at power-up or when the card is accessed, If Drive Derivative (11.028) is different between
the source and target drives. This trip can be reset and data can be transferred in either direction between the drive and the
card.
Recommended actions:
• Use a different NV Media Card
• This trip can be suppressed by setting Pr mm.000 to 9666 and resetting the drive
C.rdo NV Media Card has the Read Only bit set
181
The C.rdo trip indicates that an attempt has been made to modify a read-only NV Media Card or a read-only data block. A
NV Media Card is read-only if the read-only flag has been set.
Recommended actions:
• Clear the read only flag by setting Pr mm.000 to 9777 and reset the drive. This will clear the read-only flag for all data
blocks in the NV Media Card
C.rtg NV Media Card Trip; The voltage and / or current rating of the source and destination drives are different
186
The C.rtg trip indicates that parameter data is being transferred from the NV Media Card to the drive, but the current and /
or voltage ratings are different between source and destination drives. This trip also applies if a compare (using Pr mm.000
set to 8yyy) is attempted between the data block on a NV Media Card and the drive. The Card Rating trip does not stop the
data transfer but is a warning that rating specific parameters with the RA attribute may not be transferred to the destination
drive.
Recommended actions:
• Reset the drive to clear the trip
• Ensure that the drive rating dependent parameters have transferred correctly
C.tyP NV Media Card parameter set not compatible with current drive mode
187
The C.tyP 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
cL.A1 Analog input 1 current loss
28
The cL.A1 trip indicates that a current loss was detected in current mode on Analog input 1 (Terminal 2). In 4-20 mA and
20-4 mA modes loss of input is detected if the current falls below 3 mA.
Recommended actions:
• Check control wiring is correct
• Check control wiring is undamaged
• Check the Analog Input 1 Mode (07.007)
• Current signal is present and greater than 3 mA
Cur.c Current calibration range
231 Current calibration range error.
Cur.O Current feedback offset error
225
The Cur.O trip indicates that the current offset is too large to be trimmed.
Recommended actions:
• Ensure that there is no possibility of current flowing in the output phases of the drive when the drive is not enabled
• Hardware fault – Contact the supplier of the drive
d.Ch Drive parameters are being changed
97
A user action or a file system write is active that is changing the drive parameters and the drive has been commanded to
enable, i.e. Drive Active (10.002) = 1.
Recommended actions:
• Ensure the drive is not enabled when defaults are being loaded
dEr.E Derivative file error
246
Derivative file error with sub-trips:
Trip Diagnosis
Sub-trip Reason
