Servodrive Characteristics
3.4 Large-amplitude Frequency Characteristics
When looking at frequency characteristics with a SERVOPACK and Motor combination, the motor
speed amplitude is limited by the peak current through the SERVOPACK. The relationship between
motor speed (N) and frequency (f) is expressed using the equation given below.
