The recommended cable length when using the SERVOSTAR to source the encoder is no longer than 50 ft. (15 m). Long encoder cables tend to have high DC resistance that may create significant loading effects in the supply lines to the encoder. Please consider this carefully when designing the system. An option that would allow the use of longer lengths, implements a separate supply located at the motor to source the encoder. Quadrature signals returned to the drive are differentially connected which normally do not constitute a problem with longer cable lengths. Resolution and Accuracy A SERVOSTAR encoder-based system typically exhibits minimal inaccuracies outside of the encoder itself. To get an approximate total value the customer need only look to the specifications listed for the encoder being used.

Resolver

 The SERVOSTAR uses either single (two poles) or multi-speed (multiple poles) resolver feedback to monitor the motor shaft position. A resolver can be thought of as a transformer whose output is unique for any given shaft position (an absolute position feedback). The transformer is driven with a sinewave reference signal. Two AC signals are returned from the resolver into the Sine and Cosine inputs. All three of these sinewave signals are low-level and susceptible to noise.It is important to use properly- shielded cable and to keep it away from other noise-radiating devices and cables. It is not recommended to run the feedback and motor cables in the same conduit. Danaher Motion Kollmorgen has tested cable lengths up to 75 ft. (22.9 m). without degradation of performance. However, performance may vary, depending on motor and resolver type. Tests were performed with standard Danaher Motion Kollmorgen cable and its lowimpedance and Danaher Motion Kollmorgen GOLDLINE motor resolver. Please consult the factory for cable and resolver impedance specifications when long cable runs above 250 ft. (76 m) are desired. Danaher Motion Kollmorgen recommends twisted-shielded pair for feedback cables.
