Parallel connection

Up to 31 drives receive the same setpoints from drive 1.
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
that the difference in ground potentials between the link partners remains below 7 V.
