General Information
The SERCOS interface card of the MTA 200 is connected to the drives via the
SERCOS fiber optics cables. The connection is designed as a ring, i.e. at least
two SERCOS fiber optics cables are used depending on the number of drives.
Depending on the loacation of use, two different cables are used:
●
For wiring within the control cabinet, a fiber optic cable with a diameter of
2.2 mm is used.
●
Outside of the control cabinet, a sheathed fiber optic cable with a diameter
of 6.0 mm is used to resist higher mechnical loads.
