Re: Servo behavior question / advanced servo/PIC programming question

The spec sheet has several specs related to 60 degrees of travel. Since the sheet relates to travel in one direction I assumed all of the specs relate to movement from the "neutral position" named in the first spec. ("pulse width control 1500 usec neutral"). However, knowing that the manufacturer would not want the servo to go to mechanical stops for obvious reasons, and since there is a a spec relating to speed over 40 degrees, it is easy to guess +/- 40 degrees. In fact, in a new product sheet for the HSR-5995TG, the description is of a servo designed for 180 degree robotics operation the manufacturer states that most of it's servos are designed for 75 degrees of travel. With a little overshoot at each end, +/- 40 degrees (80 total) is pretty close to 75 degrees total travel.
