Lenze G7 Series User Manual

Resolver
The stator-supplied, 2-pole resolver with two stator windings shied by 90 degrees and a
rotor winding with a transformer winding can record both the speed and the rotor posion,
just like a single-turn absolute value encoder. The rotor posion can be determined within one
mechanical motor revoluon aer a voltage failure.
