Figure 28. Alternative connection of ”CAN GND” signal
Connections between AC drives with OPTD2
Special connection:
In this connection example, the leftmost device is the Master and the others are slaves. The Master
can send and receive data from the slaves. The slaves cannot communicate with each other.
Changing of masters is not possible, the first device is always the Master.
The OPTD2 board in the Master has the default jumper selections, i.e. X5:1-2. The jumper positions
have to be changed for the slaves: X5:2-3.
