Hello everyone! KSS 8.3, KRC4.
What is the PWM frequency of KRC4 servoamplifiers?
Is it possible to change it? For example, 4/8/16 kHz.
Thanks in advance.

Can't change it...
panic mode,
Maybe you know the exact fixed value? 4/8/16?
8kHz but what difference would that make?
Thank you. The switching frequency may cause the noise of external motor.
[size=1em]well someone was asking same thing a while ago (robot was in some radio station or whatever).
what do you know, some audiophiles claim they can hear strange things and pay $$$ for tube amplifiers, gold plated cryogenically frozen, crystal aligned cables wrapped in unicorn skin and similar snake oil related products. heck, i would probably "hear" the difference too if i was blowing money out of window on something unjustifiably overpriced.
i'll admit that my hearing may not be on pair with everyone out there (it is a simple fact of getting older) [/size]so to see if there is anything to those claims of PWM noise, i recorded the robot running sounds, run this through FFT, checked amplitude of 8 and 16 kHz spikes and - they were way below rest of the spectrum. higher harmonics are far out of human hearing range and that is without considering fact that human hearing (young or old) sensitivity to different frequencies varies.
[size=1em]if you hear axis "scream", something is wrong but i would check MADA and loop gains...

It was helpful. I guess you are right.:)
P.S.: Hope that "crystal aligned cables wrapped in unicorn skin" make some ears happy.
