3.1.5 SDO Communication
All CANopen objects and frequency converter parameters
can be accessed via SDOs (service data objects).
For a description of supported SDO abort codes, refer to
chapter 8 Troubleshooting .
COB-ID
Transmit SDO 1409 (581h)–1535 (5FFh) 580h + Node ID
Receive SDO 1537 (601h)–1663 (67Fh) 600h + Node ID

Table 3.6 Structure of a SDO-message (Request)
The CS-field contains the command and response
specifiers. See
Table 3.7 and Table 3.8 .

Saving OD entries
In standard configuration, all para OD entries are
stored in volatile (RAM) memory only. To store current
network configuration in non-volatile memory, use OD
index 1010h.
To save parameters, write the value 65766173 (save) to the
appropriated sub-index in OD: 1010h.
OD index Subindex Description
1010h
0 Number of entries
1 Save all para OD entries
2 Save all communication para OD
entries
3 Reserved
4 Save edit set-up (Danfoss specific)
Table 3.9 Saving OD Entries
Restoring OD entries
To restore factory defaults, use OD index 1011h.
To restore default parameters the value “
64616F6C ” (load)
must be written to the appropriated sub-index in OD:
1011h
OD index Subindex Description
1011h
0 Number of entries
1 Restore all para OD entries*
2 Restore all communication para
OD entries and restart

* requires power cycle
NOTICE
Frequency converter displays Alarm 80 “Drive initialised”
after restores.
3.2 Configure the Master
3.2.1 EDS File
A large part area of the system configuration is the setting
of application-related parameters. EDS (electronic data
sheet) files simplify the setting up of most of the CANopen
configurable parameters. The EDS file contains all
supported communication-specific objects (OD 1000h
+ 1FFFh) and a selected number of manufacturer-specific
objects (frequency converter parameters) in the OD range
2000h–5FFFh.
Danfoss provides a generic English EDS file covering all
voltage and power sizes for off-line configuration.
Download the EDS file from www.danfoss.com/Busines-
sAreas/DrivesSolutions/Softwaredownload/
DDFieldbus_Setup_Files.htm
.
NOTICE
The EDS files do not contain all parameters but a
selected, limited number of parameters with generic
minimum, maximum, and default values.
