Examples of peer-to-peer connections
Series connection
Each drive receives its own individual setpoint from the previous drive (classic setpoint
cascade).
1)
The shields for the interface cables must be connected directly on the devices (using a clamp, for example) to device
or cabinet ground, with a low level of impedance.
2) Twisted cable, e.g. LIYCY 2×0.5 mm
2
; with longer cables, an equipotential bonding cable should be used to ensure
that the difference in ground potentials between the link partners remains below 7 V.
3)
Optional data feedback, which drive 1 can use to monitor the functionality of the entire peer chain.
