Servo direction

[P.Wolf]

Hi fmw,

sorry, but i have to say that my last decision was completely wrong !
I tried to change the two outer poti connections at a big servo mechanism myself, and saw that there was a uncontrolled run into one end position as result.
It`s logic, because there is a fixed mechanical connection given by the gear, driving the feedback poti.
You would have to change both , the poti connections AND the motor polarity, but this would cause absolutely no change at all, the motor will turn exactly in same direction as before !

I guess the only methode to reverse such a servo system is to invert the pulse signal , coming into the servo-amplifier, or , if possible , to invert the polarity or voltage level of the input signal feeding the servo-pulser unit. This seems to be the easier way.


regards
