3.10.2 Encoder
3-phase stepper motors can be fitted with an optional encoder. This
measuring system signals the actual position if the drive is fitted with ro-
tation monitoring. A temperature sensor is integrated in the encoder.
The encoder signals and temperature sensor signals meet the PELV re-
quirements.
Rotation monitoring compares the reference position and the actual po-
sition of the motor and signals an error if the difference exceeds a spe-
cific limit value. For example, this enables detection of mechanical
overload of the motor.
An encoder can only be used with motors with connector.
