3.8.12. Sensorless – code K or Y.
The servomotors EX in sensorless version do not have a feedback cable. The connection
of the power cable has to be made regading the connection diagrams in this
documentation. In these detailed diagrams §4.3.3, do not take care the connection of the
feedback cable and keep the same connections for the other devices.
