Trip
cL.A1 Analog input 1 current loss
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
28
• Check control wiring is undamaged
• Check the Analog Input 1 Mode (07.007)
• Current signal is present and greater than 3 mA
CL.bt Trip initiated from the Control Word (06.042)
The CL.bt trip is initiated by setting bit 12 on the control word in Pr 06.042 when the control word is enabled (Pr 06.043 =
On).
Recommended actions:
35
• Check the value of Pr 06.042.
• Disable the control word in Control Word Enable (06.043)
Cur.c Current calibration range
Current calibration range error.
231 Recommended actions:
• Hardware fault - contact the supplier of the drive
Cur.O Current feedback offset error
The Cur.O trip indicates that the current offset is too large to be trimmed.
Recommended actions:
225
• 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
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.
The user actions that change drive parameters are loading defaults, changing drive mode, or transferring data from an NV
memory card to the drive. The file system actions that will cause this trip to be initiated if the drive is enabled during the
transfer and is writing a parameter or macro file to the drive. It should be noted that none of these actions can be started if
the drive is active, and so the trip only occurs if the action is started and then the drive is enabled.

Recommended actions:
• Ensure the drive is not enabled when one of the following is being carried out:
dcct dcct reference out of range for size 5 upwards only
The sub-trip number indicates the DCCT that has caused the trip.
110
Recommended actions:
• Hardware fault - contact the supplier of the drive
dEr.E Derivative file error
Derivative file error with sub-trips:
Sub-trip
246
Recommended actions:
• Contact the supplier of the drive.

Electrical Getting Basic
installation started parameters
Bit 12 of the control word set to a one causes the drive to trip on Control Word
When the control word is enabled, the trip can only be cleared by setting bit 12 to zero
Loading defaults
Changing drive mode
Transferring data from NV media card

1 The derivative file is missing or is invalid
The derivative file does not match the
