•  Interpolated Analog Sine/Cosine Encoder – up to 250 kHz (analog signal) 

 Internal interpolation - up to x4096 

 Automatic correction of amplitude mismatch, phase mismatch, signals 

offset 

 Auxiliary emulated, unbuffered, single-ended, encoder output 

•  Resolver 

 Programmable 10~15 bit resolution 

 Up to 512 revolutions per second (RPS)  

 Auxiliary emulated, unbuffered, single-ended, encoder output 

•  Tachometer, Potentiometer 
•  Elmo drives provide supply voltage for all the feedback options  

The Guitar includes built-in protection against possible fault conditions, including: 

•  Software error handling 
•  Status reporting for a large number of possible fault conditions 
•  Protection against conditions such as excessive temperature, under/over 

voltage, loss of commutation signal, short circuits between the motor power 
outputs and between each output and power input/return  

•  Recovery from loss of commutation signals and from communication errors
