1.1.8 SDO Entries
Only the “Expedited” data transfer mode (max. 4 Bytes) is used.
1) Subindex 0 (Number of supported entries ) = 3 because the device is a Server of the SDO service.
2) The structure of the Subindex 1 and 2 (COB-ID used by the SDO) is:
- Bit 31 (valid/invalid SDO); it is equal to 1 because just the Default SDOs are used.
- Bit 30 reserved = 0.
- Bit 29 = 0 because the 11-bit ID is used (CAN 2.0A).
- Bits 11-28 are not used.
- Bit 0-10 COB-ID (see table 1.4.1).
The element “node ID of SDO’s client resp. server” is not supported because just the Default SDOs are used.
1.1.9 COB-ID SYNC Entries
The structure of the 32 bits contained in the COB-ID SYNC communication parameter is:
- Bit 31 = 1 because the CANopen interface card is a “consumer” of SYNC messages.
- Bit 30 = 0 because the interface card does not create SYNC messages.
- Bit 29 = 0 because the 11-bit ID is used (CAN 2.0A).
- Bits 11-28 are not used.
- Bit 0-10 COB-ID (see table 1.4.1).
1.1.10 COB-ID Emergency
The structure of the 32 bits contained in the COB-ID Emergency Message communication parameter is:
- Bit 31 = 0 because the CANopen interface card is not a “consumer” of Emergency messages.
- Bit 30 = 0 because the interface card creates Emergency messages.
- Bit 29 = 0 because the 11-bit ID is used (CAN 2.0A).
- Bits 11-28 are not used.
- Bit 0-10 COB-ID (see table 1.4.1).
1.2 CANopen management
The user interface of the CANopen protocol is performed via the drive parameters. The parameters are controlled via hier-
archical menus. All the writing parameters referring to the eld bus are active only after the drive reset. Here following is a
list of drive parameters useful to control the CANopen protocol.
To enable CANopen, set parameter PAR 4000 Fieldbus type to CANopen or DS417.
The following parameters are available in the COMMUNICATION->FIELDBUS CONFIG menu:
PAR Par Name Type Default value Attr
4004 Fieldbus baudrate Enum None Write
4006 Fieldbus address 2 byte unsigned 0 Write
4010 Fieldbus M->S enable Enum 0n Write
4012 Fieldbus alarm mode 2 byte unsigned 0 Write
4014 Fieldbus state Enum Stop Read only
• Fieldbus baudrate = Sets the network baud rate. Values available for CANopen: 125k, 250k, 500k, 1M
• Fieldbus address = address of this slave node in the network, accepted values from 1 to 127
• Fieldbus M->S enable = if set to O data in the RPDOs are not processed by the drive
• Fieldbus alarm mode = if set to 1 the drive generates Opt Bus Fault errors relating to the loss of communication (Bus
Loss) even when the drive is not enabled.
• Fieldbus state = state of the communication for this node on the CANopen network: Stop, Pre-Operational, Opera-
tional.
