Description VLT ISD Connection Box Operating Instructions

4.3.2 ISD Servo System with 2 ISD Connection Boxes

The ISD servo system is set up with 2 connection boxes if the application requires more power than 1 connection box and 1
power supply module can deliver.
The encoder box has 2 different CAN lines (CAN I and CAN II). Both of them use the same CAN-ID.
If there is a machine with ISD 410 servomotors that are split up in 2 separate CAN lines and all of them have to listen to the
same encoder value, then encoder box CAN I should be put on the first line and encoder box CAN II on the second line.
Hereby, the drives can operate synchronously with the same guide value. CAN line II can be enabled or disabled via the SD
card parameter (General.SecondCANLineEnable).
