The CP chip contains the profile generator, which calculates velocity, acceleration, and position
values for a trajectory; and the digital servo filter, which stabilizes the motor output signal. The filter
produces one of two types of output:
• a Pulse-Width Modulated (PWM) signal output which passes via the data bus to the I/O
chip, where the output signal generator sends it to the motor amplifiers; or
