Homing an axis

On analog drives, an offset can be formed in the speed setpoint or in the speed
actual value supplied by the tachometer generator of the motor that changes as a
function of the temperature. As a result, a following error when the axis stops
cannot be completely eliminated.
If this following error is larger than machine data "Exact Stop", the axis travels at its
reference point positioning velocity toward the "Output Cam" reference point. As
soon as the output cams are reached, the axis reverses, travels to the 0 mark and
decelerates to the value set in machine data MD35xxx.
Alarm "Reference point approach was interrupted" is output. You can avoid this
alarm calibrating the drift on the drift potentiometer of the analog drive to "0",
calibrating the drift to "0" with Mdxxx, or increasing the exact stop window.
