Establishing communication between the drive and DSS
Connection between PC and drive
To avoid communication faults between the PC and the drive, please note
the following:
We recommend using the pre-assembled Bosch connection cable, part
no.: 1070 077 753, length 5 m
Distance between connection cable – power cables: at least 20 cm.
Do not permit inductive or capacitive coupling with live components.
If communication faults still occur, an annular core on the connection
lead may be helpful. Use the folding ferrite coil, part no. 1070 918 766.
Connect COM1 or COM2 of the PC to X99 of the first inverter in the drive
chain and record the PC port used.
