Re: Victor 888 High Pitch Noise
Not sure what you mean by a "tri cable" (unless you're referring to the three conductor PWM cable that links the Victors to the Digital Sidecar.)

It is normal for robots using Victor 888's to emit a high-pitched sound when operating at low speed. What you're hearing is an artifact of the motor coils being energized at a frequency that is well within human hearing range.
