Siemens ACVATIX SKB Series Manual page 7

The LED on the SKB62/MO cable adapter flashes red during the calibration, as the
positioning signal Y and the positioning feedback U do not correspond anymore. This is
interpreted as a blockage and thus indicated as an error.
If necessary, the calibration can be repeated any number of times.
