Peer link type "Parallel connection"
Up to 31 drives receive identical setpoints from drive 1
1)
The interface cable shields must be connected directly on the converter with the lowest possible
impedance to converter or cubicle earth (e.g. via a clamp).
2)
Twisted cable, e.g. LIYCY 2x0.5 sqmm; with longer cables, an equipotential bonding conductor
must be used to ensure that the difference in frame potentials between nodes stays below 7V.

Peer link type "Bus connection"
Up to 31 drives receive identical setpoints from one drive. The setpoint source drive is selected with
"Enable transmit" = 1. "Enable transmit" = 0 must be preset for all other drives.
1)
The interface cable sheilds must be connected directly on the converter with the lowest possible
impedance to converter or or cubicle earth (e.g. via a clamp)
.
2)
Twisted cable, e.g. LIYCY 2x0.5 sqmm; with longer cables, an equipotential bonding conductor
must be used to ensure that the difference in frame potentials between nodes stays below 7V.
