Feedback

Every closed servo system will normally require at least one feedback device for sending actual
values from the motor to the servo drive. Depending on the type of feedback device used, informa-
tion will be fed back to the servo amplifier using digital or analog means.
SERVOSTAR 640/670 supports the most common types of feedback device whose functions must
be assigned with the parameters
in the setup software. Scaling and other settings must always be made here.

The table below provides an overview of the supported feedback types, their corresponding para-
meters and a reference to the relevant connection diagram in each case. On each of these, the pin
assignment shown on the encoder side relates to the Kollmorgen motors.
