Encoders with reference pulse
The reference pulse of an analogue incremental encoder corresponds to the index pulse of
a digital incremental encoder. Information as to whether the angle encoder has such a
pulse can be found on the data sheet of the angle encoder.
Risk of injury due to uncontrolled drive movements.
The servo drive corrects the actual position if the index pulse is activated. In the case of
encoders with unsymmetrical index pulses, this may cause the drive to overspeed. This
is why, if in doubt, the index pulse evaluation should be deactivated.
Usually, linear motors do not include cyclic index pulses. However, there may be a
single index pulse that can be used for homing.
