7.1.4 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.

(LSB)
Table 7.4 Structure of the SYNC COB-ID
Bits 29 and 30 must be static (not changeable). If a device
is not able to generate SYNC messages, an attempt to set
bit 30 generates an abort message (abort code: 0609
0030h).
Devices supporting only the standard CAN frame type
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.

7.1.5 1008h Manufacturer Device Name

This object contains the device name as defined in
parameter 15-40 FC Type.

7.1.6 100Ah Manufacturer Software Version

This object contains the frequency converter software
version from parameter 15-49 SW ID Control Card.

7.1.7 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 way to verify the availability
of the master on the bus, which is necessary for the
timeout functionality of the frequency converter.
This object contains the time between 2 master requests in
ms.
34
CANopen
This bit is ignored
Device does not generate SYNC message.
Device generates SYNC message (the frequency
converter does not support this bit).
11-bit ID (CAN 2.0A)
29-bit ID (CAN 2.0B)
If bit 29=0: CAN ID uses bits 0–10. CAN ID does
not use bits 11–28 and sets them to 0.
If bit 29=1: CAN ID uses bits 28–11 for higher
18 bits and bits 10–0 for lower 11 bits.
Bits 10-0 of COB-ID.

7.1.8 100Dh Life Time Factor

This object contains the lifetime factor used in node
guarding. This factor, multiplied by the value of 100Ch
defines the time after which the node guarding function
must poll the slave. If the slave does not receive a guard
telegram within this time, the slave issues warning 34,
Fieldbus communication fault.

7.1.9 1010h Store Parameters

In the standard configuration, the contents of parameters
written via fieldbus are stored in volatile memory, and the
changed data is lost after a power cycle. Use this object to
store the changed frequency converter parameters in non-
volatile memory.

Table 7.5 1010h Store Parameters
Writing the save value (0x65766c173) to subindex 1 saves
all frequency converter parameters of all set-ups into non-
volatile memory. Subindex 4 does the same for the edit
set-up. This is done via parameter 10-31 Store Data Values.

7.1.10 1011h Restore Default Parameters

Use this object to set the frequency converter to factory
default settings by writing the load value (0x64616F6C) to
subindexes.
The parameters are set to default values after the next
power cycle, which has to be initiated manually.
