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.
Pin number Terminal Colour Name
1 – – Reserved
2 CAN_L Blue CAN LOW
3 Drain (bare) Screen
4 CAN_H White CAN HIGH
5 – – Reserved
Table 8.7 Cabling
8.2.5 Check 4: Is the Correct EDS File
Installed?
Download the correct EDS le 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 nal nodes. Termination is
performed between terminal 2 (CAN_L) and 4 (CAN_H)
with a resistor:
•
121 Ω.
•
1% metal lm.
•
¼ W.
8.2.7 SDO Abort Codes
The abort code describes the error code when an SDO
generates a failure.
Abort code Description
0503 0000h Toggle bit not alternated.
0504 0000h SDO protocol timed out.
0504 0001h Client/server command specier not valid or
unknown.
0504 0002h Invalid block size (block mode only).
0504 0003h Invalid sequence number (block mode only).
0504 0004h CRC error (block mode only).
0504 0005h Out of memory.
0601 0000h Unsupported access to an object.
0601 0001h Attempt to read a write-only object.
0601 0002h Attempt to write a read-only object.
0602 0000h Object does not exist in the object dictionary.
0604 0041h Object cannot be mapped to the PDO.
0604 0042h The number and length of the objects to be
mapped would exceed PDO length.
0604 0043h General parameter incompatibility reason.
0604 0047h General internal incompatibility in the device.
0606 0000h Access failed due to a hardware error.
0607 0010h Data type does not match, length of service
parameter does not match.
0607 0012h Data type does not match, length of service
parameter too high.
0607 0013h Data type does not match, length of service
parameter too low.
0609 0011h Subindex does not exist.
0609 0030h Value range of parameter exceeded (only for
write access).
0609 0031h Value of parameter written too high.
0609 0032h Value of parameter written too low.
0609 0036h Maximum value is less than minimum value.
0800 0000h General error.
0800 0020h Data cannot be transferred or stored to the
application.
0800 0021h Data cannot be transferred or stored to the
application because of local control.
0800 0022h Data cannot be transferred or stored to the
application because of the present device state.
0800 0023h Object dictionary dynamic generation fails or no
object dictionary is present (e.g. object dictionary
is generated from le and generation fails
because of a le error).
