Replace ACS850 with ACS880
I am in the process of replacing a failed ACS850 drive with a ACS880, i noted application program ming is used on ACS 850, i do not have the drive studio software to analyse the setup in the acs850.
Noted some parameters in the acs850 are not in the acs880.
generally the performance of ACS880 are better than ACS850, but if you have SPC program inside the old ACS850 and you not have the appropropriate tool to examine, named Drive SPC, you can not substitute the old drive with the new, without the same features that is named Adaptative Program in ACS880.
If you not have appropriate SW to examine the project, IMHO you must ask to ABB service in your area
