Troubleshooting
8.2.2 Check 2: Error Counters
Check the values of the TEC and REC in
parameter 10-05 Readout Transmit Error Counter and
parameter 10-06 Readout Receive Error Counter.
8.2.3 No Communication with the
frequency converter?
If there is no communication with the frequency converter,
proceed with the following checks:
8.2.4 Check 3: Is the Cabling Correct?
Check that the cables are connected to the correct
terminals as shown in the diagram.

Table 8.7 Cabling
8.2.5 Check 4: Is the Correct EDS File
Installed?
Download the correct EDS file from www.danfoss.com/
drives and www.danfoss.com/BusinessAreas/DrivesSolutions/
Softwaredownload/DDFieldbus_Setup_Files.htm.
8.2.6 Check 5: Is the bus connection
terminated at both ends?
If not, terminate the bus connection with termination
resistors at the initial and final nodes. Termination is
performed between terminal 2 (CAN_L) and 4 (CAN_H)
with a resistor:
•
121 Ω.
•
1% metal film.
•
¼ W.

Description
Toggle bit not alternated.
SDO protocol timed out.
Client/server command specifier not valid or
unknown.
Invalid block size (block mode only).
Invalid sequence number (block mode only).
CRC error (block mode only).
Out of memory.
Unsupported access to an object.
Attempt to read a write-only object.
Attempt to write a read-only object.
Object does not exist in the object dictionary.
Object cannot be mapped to the PDO.
The number and length of the objects to be
mapped would exceed PDO length.
General parameter incompatibility reason.
General internal incompatibility in the device.
Access failed due to a hardware error.
Data type does not match, length of service
parameter does not match.
Data type does not match, length of service
parameter too high.
Data type does not match, length of service
parameter too low.
Subindex does not exist.
Value range of parameter exceeded (only for
write access).
Value of parameter written too high.
Value of parameter written too low.
Maximum value is less than minimum value.
General error.
Data cannot be transferred or stored to the
application.
Data cannot be transferred or stored to the
application because of local control.
Data cannot be transferred or stored to the
application because of the present device state.
Object dictionary dynamic generation fails or no
object dictionary is present (e.g. object dictionary
is generated from file and generation fails
because of a file error).
