HiTec HSR-1425CR Servo Question

Help & Support Robot Parts
1

Anyone know how to run this servo? I am using a PICAX-28x1 with a Pololu Micro Serial Servo Controler.

Thanks for all help in advance.

So is this how I would program it then?

serout 7,N2400,(255,0,50) for CCW

serout 7,N2400,(255,0,150) for stop

serout 7,N2400,(255,0,250) for CW

Thanks for the help so far.

Ok well I got it working now.

Thanks for the help.

But for future reference for any one that uses this servo, for some reason (maybe its the Pololu Micro Serial Servo Controller) 150 does not stop the servo but a number between 132 and 138 (I use 135) stops the servo (or slows it down enough to make it look like it has stopped).

Thanks again for all the help.

Yes, that should work (as long as the neutral value is at 150). Also, the rotation speed will depend on how far the value you send is from the neutral point on either side of it.

The HSR-1425CR looks like a standard servo with the 3 wire connectors, though when you send a servo signal, there is no feedback. The continuous rotation servo accepts normal R/C signals (4.8V to 6V timed pulse between ~500us and 2500us repeated every 20-30ms). 1500us is neutral (no speed) and increasing / decreasing the pulse will cause the servo to rotate faster CW or CCW.
