3.8.9. Feedback system
3.8.10. Shaft rotation regarding the connection.
With the connection explained in the documentation and with a positive speed request on
the drive, the shaft will turn in clockwise direction (see customer shaft end).
3.8.11. Resolver 2 poles transformation ratio = 0.5 – code A
Output impedance
(primary in short circuit
whatever the position of
the rotor)
Dielectric rigidity
(50 – 60 Hz)
Operating temperature
range
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.
