SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description:
Setting the baud rate for the CAN bus.
The appropriate bit timings are selected that are defined in p8623 in the associated sub-index.
Example:
Baud rate = 20 kbit/s --> p8622 = 6 --> associated bit timing is in p8623[6].
Value:
0:
1 Mbit/s
1:
800 kbit/s
2:
500 kbit/s
3:
250 kbit/s
4:
125 kbit/s
5:
50 kbit/s
6:
20 kbit/s
7:
10 kbit/s
Dependency:
Refer to: p8623
Note:
The parameter is not influenced by setting the factory setting.
Description:
Sets the bit timing for the C_CAN controller to the associated and selected baud rate (p8622).
Bits are distributed to the following parameters of the C_CAN controller in p8623[0...7]:
Bit 0 ... 5: BRP (Baud Rate Prescaler)
Bit 6 ... 7: SJW (Synchronization Jump Width)
Bit 8 ... 11: TSEG1 (Time Segment 1, before the sampling point)
Bit 12 ... 14: TSEG2 (Time Segment 2, after the sampling point)
Bit 15: Reserved
Bit 16 ... 19: BRPE (Baud Rate Prescaler Extension)
Bit 20 ... 31: Reserved
Example:
Baud rate = 20 kbit/s --> p8622 = 6 --> associated bit timing is in p8623[6] --> 0001 2FB6
Index:
[0] = 1 Mbit/s
[1] = 800 kbit/s
[2] = 500 kbit/s
[3] = 250 kbit/s
[4] = 125 kbit/s
[5] = 50 kbit/s
[6] = 20 kbit/s
[7] = 10 kbit/s
Dependency:
Refer to: p8622
Note:
The parameter is not influenced by setting the factory setting.
