In this video, we will talk about how to set up
an ATS48 soft start for your standard basic first time programming.
Keep in mind that we're not going to go into detail about how
to program your relays or your other functions, but just simple programming.
OK.
So from a first power up, in your main menu,
you want to go ahead and press the down arrow key.
And you want to start by going into the SEt menu, S-E-T. Press Enter on here.
The first parameter is I-N. You want to enter on that.
And this is your motor full load amps, or actual motors current rating.
So you want to adjust that value according
to what your motor nameplate specifies.
And when you are adjusted the value, enter on that to save it.
It will blink once.
Once that's done, you can escape back to I-N
and scroll down into the ACC parameter, which is your ramp up time.
And you can make this whatever you like.
Normally for certain applications, you don't want
to have too long of a ramp up time.
But you don't want to have a second or two of ramp up time either.
So you want to make sure you pick a range that best fits your application.
Normally around 10 is your default value here in most cases.
Again, just like last time, you can go ahead and adjust the value
and then enter on to save it.
And it will blink once as well, like last time.
So let's go ahead and do that.
The next parameter I would go to-- actually,
we skipped ILt. I would go there next after I-N, actually.
ILt is your current limitation.
From the factory, it's set to 400%.
So this is the how much of an in-rush you're
going to experience at initial startup.
And 400 is the default. In some heavy duty applications where
if it's severe duty, and you need a lot of torque,
I've seen where that can be adjusted above 400 if necessary.
But again, be careful about adjusting it too high.
The motor has to be able to withstand that much of a derating.
But that's the current limit regardless.
The next parameter in this list you want to look for is actually in another menu
altogether.
So escape back to SEt and scroll down to DRC,
Enter, and then find the parameter CLP, Charlie Larry Paul, Enter.
OK.
So this CLP parameter is basically a torque control parameter,
meaning that if it's turned on, the soft start is actually
trying to modulate the torque based upon what the motor is calling for.
If you turn it off, which is what is sometimes beneficial,
it basically allows a soft start to follow the actual ramp up time
as we have programmed, which is right now 10 seconds in my own soft start.
But it's going to follow your actual acceleration time.
So that's beneficial in some applications,
such as fans or low torque applications.
You want to let it run based upon the actual voltage of a frequency ratio,
and not necessarily the soft starts torque modulation.
For heavier torque though, that's kind of up to the application.
But that's basically how you program an ATS48 soft start.
Again, we're not going over every single setting in the soft start.
There's a lot of things we didn't look at, like your relay assignments,
your logic output assignments, et cetera.
So if you need any help with those kind of configurations,
plus see our other FAQs that are available online.
