Can't get started SSC32 and HS5995

Lynxmotion Electronics & Software

I have my SSC32 hooked up to my computer, the power is being supplied by a 9 volt supply, right now, although it was originally provided by a 6V supply. Just an easier hookup with the 9V so it is easier when I’m experimenting.

Anyway, I also switched because my 6V supply has very nice high amperage and was smoking my servo.

When I hook up the servo to the SSC32 it moves clockwise all the way to the far right stop and pins there trying to move past the full range of motion. I can’t get it to stop pinning on the extension. I try stuff, hook the servo up, then it pins and I unhook it.

I have downloaded lynxterm but it isn’t helping me alot since no matter what I change it seems to still do the same thing.

Just some general thoughts:

  1. 6v should not harm your servo, 9v can possibly make it “smoke”.
  2. If smoke did come out of your servo, it may be ruined.
  3. With analog servos a bad control signal to the servo can cause it to go to an extreme position.
  4. Check your power supply voltage with a multimeter to make sure the voltage is not higher than stated.

So if my power supply does check out at 6V I should just be able to plug and play essentially the servo right? No settings or special configuration required?

I seem to be having lots of trouble with these digital servos, should I just switch to analog? What do you suggest?

I don’t see anything in the documentation that says you need to do things differently if you are using digital versus analog servos. Couple of questions.

Assuming I’m running at the same power…

Can the SSC-32 run both analog and digital servos at the same time, and what do I need to do if it can?

Still have the question above about the HS5995 any idea why it is trying to go past the operating range when first powered on?

Hello geigerwolf,

There is no difference between analog and digital servos as far as the SSC-32 is concerned. I believe what you have is simply a bad servo. Try connecting a different servo to the SSC-32 and see what you get.

BTW the SSC-32 does not send pulses immediately upon power up. Unless you have enabled some register settings on the V2 version. So the servo must be faulty. :wink:

Just in case I have now accidentaly set anything as I was trying to get things working with lynxterm. What is the best way to clear the registers?

Connect to the SSC-32 with Lynxterm, click on Reg and then click on Default.

Thanks, I’ll do that and I’ll try one of my other servos tomorrow night.

Make sure you aren’t pluging the servo connector onto the ssc-32 pins 180 deg out of correct position.

Yellow is pulse on the hitech servos right?

Looking at the servos, that appears to be correct.

Well somewhere along the way it appears one of my HS5995s bit the dust. I have three more hs5995s, and after I cleared the register they responded as expected to lynxterm.

That much is now AOKAY, except of course I have one fried $125 servo, but that has nothing to do with SSC32.

Now, I’m guessing that the offsets and ranges are best if specified in lynxterm as they are maintained in the register. That way the Brookshire VSA software won’t need to be seperatly configured and won’t over rotate any servo.

Can’t wait to get going!
