The ISD 511 is a high-performance decentral servo motion solution. In this decentral system, the ISD 511 servo drives are operated
in a DC group and controlled by a PLC.
The hybrid cables used in the servo system contain the DC-link supply, the Real-Time Ethernet, U
AUX
, and STO signals. For further
information on hybrid cables, see
and
A maximum of 68 ISD 511 servo drives can be connected on 1 line and a maximum of 5 ISD 511 servo drives can be grounded in 1
group via the 2 PE screws on the servo drive (see
5.3.1 Grounding the ISD 511 Servo Drive
). The minimum cable cross-section is
4 mm
