9400 regenerative power supply module | Parameter setting
"CAN on board" system bus
Implemented CANopen objects
158 L EDS94ARNExxxx EN 2.3 - 06/2014
Example
Parameter data channel 2 of the controller with node address 4 is to be activated.
For this purpose, bit 31 must be set to "0" (≡ "SDO is valid") in the subindexes 1 and 2 of
the I-1201
object.
The two "write request" commands must be sent from the master to the nodes via the
basic SDO channel.
Calculation of the identifiers
Identifier (COB-ID) = basic identifier + node address (node ID)
Basic identifier SDO2 from the master to the drive: 1600 (0x640)
Identifier = 0x640 + 0x4 = 0x644
Basic identifier SDO2 from the drive to the master: 1472 (0x5C0)
Identifier = 0x5C0 + 0x4 = 0x5C4
Resulting data (data 1 ... data 4)
[6-11] Assignment of the data telegram for subindex 1
[6-12] Assignment of the data telegram for subindex 2
Assignment of the user data
[6-13] Assignment of the user data for writing to subindex 1
