for a list
of error codes that can be recorded in this object.
1005h COB-ID Sync Message object
This index defines the COB-ID of the Synchronization Object (SYNC). It also defines whether the
device generates the SYNC.
The structure of the SYNC COB-ID is:
Bit
Value Meaning
31 (MSB)
X
do not care
30
0
1
Device does not generate SYNC message
Device generates SYNC message (not supported)
29
0
1
11-bit ID (CAN 2.0A)
29-bit ID (CAN 2.0B)
28 - 11
0
X
if bit 29=0
if bit 29=1: bits 28-11 of 29-bit-COB-ID
10-0 (LSB)
X
bits 10-0 of COB-ID
Bits 29, 30 must be static (not changeable). If a device is not able to generate SYNC messages, an
attempt to set bit 30 will generate an abort message (abort code: 0609 0030h).
Devices supporting the standard CAN frame type only will either ignore attempts to change bit 29 or
respond with an abort message (abort code: 0609 0030h).
The first transmission of SYNC object starts within 1 sync cycle after setting Bit 30 to 1.
1008h Manufacturer Device Name
This object contains the device name as defined in par.15-40
1009h Manufacturer Hardware Version
This object contains the Danfoss FC hardware version
100Ah Manufacturer Software Version
This object contains the Danfoss software version as displayed in par.15-49.
100Ch Guard time
This object is used in node guarding, an error control service used in addition to the heartbeat
mechanism to detect failure in the CAN network.
Node guarding provides the only possible verification of the master’s availability on the bus, for the
drive’s timeout functionality.
This object contains the gap between two master requests in ms.
100Dh Life time factor
This object contains the lifetime factor used in node guarding. This factor multiplied with the contents
of o100Ch defines the time after which the slave has to be polled by the master’s node guarding
request. If this time has elapsed without the slave being polled by a guard telegram, a warning 34 will
be issued by the slave.
1010h Store parameters
In the standard configuration, the contents of parameters written via fieldbus are stored in volatile
memory, i.e. the changed data will be lost after a power cycle. This index permits non-volatile storage
of all drive parameters which have been changed.
