3.9. Feedback system
3.9.1. Resolver
A resolver determines the rotor position.
Its signals are processed by the drive in order to control the stator currents, the speed and
the position.

In this case, Parker can provide Resolver Sensor cables, to be placed between the motor
and the drive, with standard lengths of 1, 2, 3 or 4 meters ; its part number is built as follows
“CBFRE0H0-SRX-000-00x0-00” where “x” is the length in meter.
