What does "resolver based" mean?
A resolver sensor is the preferred choice for angular position measurement in harsh environments and for safety press controls applications. The resolver sensor resembles a rotary transformer where the output coils are oriented 90° to each other and each produces a voltage complementary to the other. The excitation coil, or the primary coil, is supplied a sine wave. A resolver based press control uses a resolver for its position feedback. It is coupled to the shaft directly
