ID #25 - Speed Reference: To set the speed reference via the network, set this parameter to
NETWORK REFERENCE. This parameter is mapped to AC/DC Drive Object 0x2A-1-4.
ID #26 - Network Reference Frequency: Controls the drive speed reference if parameter ID #25 is
set to NETWORK REFERENCE. This parameter is mapped to Parameter Object 0x0F-26-1.
B.4 DEVICENET TM IMPLEMENTATION FOR THE SCD SERIES DRIVE
The following describes the DeviceNet TM network protocol implementation on the SCD Series drive.
The SCD Drive can be operated as a slave device on a DeviceNet TM network. It supports Explicit
Messages and the following I/O messages of the predefined master/slave connection set:
- Polled
- Bit Strobe
- Changed of state
- Cyclic
NOTE: It does not support the Explicit Unconnected Message Manager!
To assist in verifying data integrity, attribute Configuration Consistency Value of the Identity Object
has been implemented.
To simplify setup and operation, implemented classes and behavior conform to the AC DRIVE profile
as specified in the ODVA DeviceNet
TM standard.
To assist in recovery from Communication Faulted condition, Offline Connection Set messages are
supported. The SCD supports the following Group 4 message types:
Group 4 Message ID 2C - Communication Faulted Response Message
Group 4 Message ID 2D - Communication Faulted Request Message
Using these messages, the user will be able to identify a faulted drive and when possible, re-establish
communication without disconnecting the network or resetting the drive. After receiving "Identify
Request Message" while in Communication Faulted state, the two upper decimal points on the drive's
display will flash and the display will indicate "Idn".
The following baud rates are available: 125 kbps, 250 kbps, 500 kbps
The SCD drive supports the following object classes:
1. Identity Object - Class 0x01 7. Parameter Group Object -Class 0x10
2. Message Router Object - Class 0x02 8. Motor Data Object - Class 0x28
3. DeviceNet Object - Class 0x03 9. Control Supervisor Object - Class 0x29
4. Assembly Object - Class 0x04 10. AC/DC Drive Object - Class 0x2A
5. DeviceNet Connection Object - Class 0x05 11. Acknowledge Handler Object - Class 0x2B
6. Parameter Object - Class 0x0F
WARNING!
Make sure it is safe to operate the driven equipment prior to starting the SCD Series drive from the
network. Damage to equipment and/or injury to personnel can result!
