Title: Question About Adding A Servo In Project Designer
Post by: Sylvestre on November 23, 2011, 04:21:07 PM

Hey guys,

In Project Designer, when I add a hardware PWM servo it asks for the "center" and "range" of the servo.  What are these parameters and where can I find the information I need?  I am using a Hitec Hs- 65mg servo.

Thanks

Servo-city's website has a lot of specs for Hitec and Futaba servos.  The HS-65MG is listed here (http://servocity.com/html/hs-65mg_mighty_feather.html).  I like the picture because it makes it fairly self-explanatory:

As you can see neutral is at 1500 and it can range + or - 900 for a total range of 600 to 2400 microseconds.  Of course these are idealized and may vary some from servo to servo, particularly if you buy generic servos.  I recommend testing the range of the servo so you can get full range without driving it outside its limits.

Alright thanks.
