Before replacing the drive you must save the parameters in HIM through the copycat function and then download the new inverter

I recommend using Drive Executive. This way you can save the parameters to an offline file. If you have a catastrophic failure, you can always recover the file to a new drive, even when the HIM is lost. It's also useful if you want to recover parameters. I worked with a fellow who was messing with drive parameters to "improve" it. Whatever he did, he messed something up and it was constantly tripping on overvoltage. He couldn't fix it, and couldn't remember all the changes he made (first mistake!). After messing around with it, unsuccessfully, I just reverted to a saved parameter file. Problem was solved. You can use the HIM, as mentioned above, but use Drive Executive instead. That's my suggestion.

If yo do not have Drive Executive ($$), you can use Connected Component Workbench (free) currently at version 7. Alan
