CAN
The CAN bus is connected via terminal block X6. Depending on the variant, an 8, 12 or 16-pole plug-in terminal block is used.
X6 | PIN | Designation | Notes |
|---|---|---|---|
| 1-4 | - | Voltage supply |
5 | Shielding | Shield connection (FE) | |
6 | CAN_GND | Reference potential CAN | |
7 | CAN_H | CAN data signal high | |
8 | CAN_L | CAN data signal Low | |
9-12 | - | ||
13-16 | - |
The terminals for the CAN bus are always identical, independent of the above design.
