7.11.3 Master follower configuration
The OPTD2 board in the Master has default jumper selections, i.e. X6:1-2, X5:1-2. For the followers,
the jumper positions have to be changed: X6:1-2, X5:2-3. This board also has a CAN communication
option that is useful for multiple drive monitoring with NCDrive PC software when commissioning
Master Follower functions or line systems.
