i need some info please

i wanna know if i send pulses to a servo and i put a 5 or 10 mseconds between pulses (not 20 ms) what happen? is it dangerouse?

it means that signal ferequency is 100Hz or 200Hz...

if yes then why? and how much? !

when i test this.servo works normally.

thanks

I don't recommend framerates above 100Hz since some servos will not operate correctly and/or can be damaged.

FWIW, slightly faster updates can sometimes increase the response of non-digital servos. But it can also result in additional servo stress due to the increased motor activity.

Futaba and JR sell super-servos that are rated for fast update use (tail rotors on heli's). I think they require >150Hz. If for some reason your app needs to use fast updates, then this sort of servo could be used.

i use a standard rc servo, not a super servo or digital one.

i tested my servo with framrates equal to 200Hz and it was normal.

and it wasnt worm up.

whats your opinion? can i use this servos with 100 ro 200 Hz framrate or not?

thanks

whats your opinion?

As I mentioned, I would not use more than 100hz. If you want to use 200Hz with standard servos, and the project is for your own use, then use whatever works for you. If you intend to distribute the project, then stick with the standard ~50Hz signal timings. This is just my opinion, nothing more.
