Rotating direction The rotating direction in which there
have to be ascending or descending
position values can be defined. Default
setting: Ascending position values when
looking at the flange and rotating the
shaft clockwise.
Parameter defining the steps per turn as
well as the total resolution.
Description
Screen: connected to housing
Parameter for setting the encoder to a
requested position value assigned to a
defined shaft position of the system.
The offset of encoder zero point and
mechanical zero point is stored in the
encoder.

General informations
Self-heating interrelated to speed, protection, attachment
method and ambient conditions as well electronics and
supply voltage must be considered for precise thermal
dimensioning. Self-heating is supposed to approximates
6 K (IP 65 protection) respectively 12 K (IP 67 protection)
per 1000 rpm. Operating the encoder close to the maximum
limits requires measuring the real prevailing temperature at
the encoder flange. 3
