This is part 2 of our demonstration on Nidec's (Emerson) family of servos. In Part 1, we
discussed the hardware and features of Epsilon, Digitax, and Unidrive SP. Today I would like to give you a tour of the
extremely intuitive programming software, Power Tools Pro.
Here's a look at Power Tools Pro. On the left-hand
side is my menu tree. Here's where I do everything from a motor setup, setting
up my IO, motion profiles, and more.
So for this example, to setup my demo unit I'm
going to choose motor. On the top is my catalog of all the Nidec (Emerson) motors that
are currently available. Most of these are pretty well set from the factory
however I still recommend doing an auto tune. If you have a third party motor,
you can choose Auto Tune and it will help tune that motor specifically to that
For this I'm going choose XP604. Next I want to show you user units. Here's
where you can set up let's say you have a gearbox, and you can choose how many
motor rotations are per output shaft of the gearbox. Makes it pretty easy for
setting up the rest of your motion profiles.
First thing I'm going to do is set up my job.
So for the jog, I'm going to choose a velocity of 200 with an acceleration of
150 and decel of 150. As you can see, it actually already calculated my time
and how long it's going to take. Makes it pretty nice for seeing how this is
actually going to operate.
Next thing I'm going to set up my home. This
example I've chosen a velocity of negative 50 with an excell and decell of 50. Then
I also want this to home out from my sensor and then to my marker for a little
more precise home.
I'm going to choose an index distance of 200
revs and let's go a velocity of 1,000. With an Excel of 500 and decel 500. One
of my favorite features is the graphical representation down below. It shows
actually how long it's going to take, and how many revs, so it makes it pretty
easy to understand without actually having to try to do it.
Setting up I/O
Next thing I want to do is my I/O setup. Here's
where I can assign the inputs that are wired to my drive to how this thing is
going to operate. So first thing I want to do is set up my jog. So I'm going to
simply say I want the first switch to jog it plus. Drag and drop that over, and
then let's do a minus jog as well. Then, I want to initiate let's say my home. Assign
it to number-3 and then just to simulate the homing switch, let's assign that
to input number four. And then finally, we need to assign something to initiate
the index. Drag that one over to input number five.
Okay now that inputs are assigned, we're ready
to download this and give it a try.
Go to device and download I'll look for the
drive and it should download.
Now that we've downloaded, you can see we're
online. l I can get a signal saying we're connected, and my actual position
feedback. So if I want to try this out before anything is wired, I can do that.
So to try that out from this first leg jog and
hit the arrow buttons left and right, Now as you can see based on my position
feedback I'm actually moving. I can try out my home, let's hit the start button
then I'm just gonna simulate turn on input number three, and it homed out.
Now let's try out my index. so without inputs
wired at all, I can try this out. If you want to see the status of the inputs
click on inputs and these boxes will actually highlight green when the inputs
So let's go ahead and try the inputs now and
see how well this thing works. Ok now that the drive is programmed, let's see
if this works. First thing I'm going to do is try and jog, hit the first input
that I've programmed going in forward direction and reverse.
Ok a homing sequence.
Simulate the prox switch,
back to the marker,
and now finally an index.
As you can see programming the drive is pretty simple. This was just a basic application, but these
drives can do even more advanced profiles like gearing, camming, and can even
go into a torque mode. As you have just seen Nidec (Emerson) servo’s are user friendly and can
accommodate to almost any application.
