Hi Guys,

Now it's drive issues...I can't seem to find the Resource Manual for a PF40. You know... The one where it actually tells you how it works. If anyone has experience in setting up what used to be called an "Electronic Shearpin" in a PF40, it would be very helpful to hear about how that was done. To be clear, I'm not talking about 150% overload for 60 Seconds. I'm thinking more like 150% for 1 Sec.

Thanks for any help!

Look for something called software current limit. It is in there, and I am working from memory from a green acres ISP connection without a copy of the pdf. I think there may be an associated level and/or time adjustment parameter too.

Hi Okie,

I found A098 [SW Current Trip] - Enables software instantaneous current trip (within 100mSec). That looks great! It will be even better if I can find an associated Time Parameter.


Thanks, this is headed in the right direction.

Yeah, I think that parameter is all you get with the lowly "Component Class" drives. Now that I have access to the manual, I did not find any other parameter to give control of the response time.

I just found out about the "Component" part. I have used these before and it never came up. It seems that the output current can be retrieved and then I can make my own.

Look at the ACS355 from ABB. They are price competitive with the PF40, and very capable drives.
