Deactivation of the 2nd parameter channel in the Lenze setting

Question:
Why does the 9400 Servo Drives CAN on-board connection only have one activated parameter channel SDO 1 in the Lenze setting?

Answer:
According to the CANopen specification DS 301, each CAN node must only have one SDO parameter channel to ensure that the maximum possible number of nodes of 128 can be reached.
For 9400, there are, however, up to 10 SDO channels available which can be enabled via the Lenze codes L-C00372 and L-C00373.
