The resolver is a measuring principle optimally suited for tough environmental conditions. Its transformer functions do not require any electronic components in the motor. Resolution and accuracy are limited compared to inductive or optical position measurement systems. All of the information contained in the resolver signals is used by the ACOPOSmulti encoder plug-in modules to evaluate the signal, allowing extraordinarily good results. This makes it possible to detect broken connections, shorted lines and encoder supply failure (reference signal), in addition to determining position information.
