Absolute encoder connection
Caution!
Never touch the connection contacts on the position absolute encoder or on the cable! The electronics can be
destroyed by static electricity.
"
The absolute encoder must be connected to the frequency inverter.
"
The absolute encoder contains components that may be damaged by electrostatic discharge. The
body of the person touching them must
fi
rst be discharged, for example, by touching a conductive,
earthed object, (e.g. bright metal parts of a control panel), immediately beforehand.
"
A shielded cable must be used for the encoder connection. It is recommended to use a ZIEHL-
ABEGG SE cable which guarantees a suf
fi
cient shield connection.
"
The absolute encoder must not be detached mechanically in order not to lose the factory settings. If
the absolute encoder has been detached, the new encoder-offset has to be determined with the
frequency inverter. Please see the inverter operation instructions for this procedure.
