Indications and Operation of the Function Modules Rexroth IndraDrive FCS01.1
DOK-INDRV*--FCS01*****-IB01_EN-P
Note: The settings via the rotating encoding switch are not
transmitted into the frequency converter.
The use of line type A results in the following lengths of a bus segment:
Transmission speed [kBit / s] Max. allowed line length [m]
9,6 1200
19,2 1200
45,45 1200
93,75 1200
187,5 1000
500 400
1500 200
3000 100
6000 100
12000 100

Note: Only when the specified line parameters are observed, the
guaranteed transmission speeds or transmission distances
can be maintained without any problems.

Fig. 9-19: Bus cable requirements
Note: The line shield must be connected to the functional
grounding (usually the electrically conducting mounting plate)
to avoid EMC damage to the device.
In the FCC01.1F-PBx function module, connect the line shield
over a large area with the metal housing of the D-SUB
connector and the
functional grounding in the Profibus
connector.
