10 Encoder – Mounting and Connection
10.1 Mounting
See the mounting instructions supplied with the particular encoder.
10.2 Screening
According to the Profibus DP specification, it is always recommended to use screened cables
and to attach the screen on both sides. For detailed information see 'Cable Screening' (4.3.5) in
in this document.
To achieve optimum screening effectiveness and to prevent mass equalisation currents from
flowing across the screen, note the following:
•
It must be ensured that there is a good electrical connection between the metal housing of
the encoder and the earthed metal parts of the system/machine. This is usually achieved by
the metallic connection across the encoder flange.
•
If the fixing method used does not have a well-conducting electrical connection, additional
measures in the form of an earthing cable must be taken.
Encoders of the type
ATM 90-P
may, due to their internal arrangement, require
additional earthing even with a good metallic connection.
