1)
Type of peer connection "Bus connection"
Up to 31 drives receive identical setpoints from a drive. The transmitting drive is selected with
"Enable transmit" = 1. "Enable transmit" must be = 0 for all other drives.
1) The interface cable shields should be connected at low impedance directly to the converters on the converter or
cabinet ground (e.g. using a clamp).
2) Twisted-pair cable, e.g. LIYCY 2x0.5 qmm; in the case of longer cable runs, an equipotential bonding conductor should
be used to ensure that the difference of the frame potentials between the connected units remains below 7V.
