FS90 and FS90FB

Support Servo controllers and servos

Hi. I just wanted to ask if FS90 servo motor and FS90FB share the same control logic. Which means if I don’t plug the feedback pin on FS90FB, will it behave exactly the same as FS90?

Hello.

The FS90-FB servo is just a modified version of the FS90 servo that provides access to the internal feedback. Each servo might have some unit-to-unit variation (even between the same models), but my expectation is that they should behave the same (whether or not you are monitoring the feedback).

Thanks for the response. Just want to confirm, unlike FS90R, which cannot substitute FS90 since they have completely different control logic, FS90FB can serve as a alternative of FS90?

The FS90R is a continuous rotation servo, whereas the FS90 and FS90-FB are normal position-controlled servos. The FS90-FB should work as a direct replacement for the FS90.
