Resetting VFDs to Factory Default Parameters
Posted by Marshall Wolf on Dec 11th 2023
Sometimes we just need a reset!
As simple as this may sound, searching through the tomes that are the manufacturer’s instruction manual can be a bit daunting. That’s why Mac in tech support put together these simplified resetting guidelines for some of our more popular drives.
AC Tech – SMV Series

Commission Code: No. P199 “Program Selection”
For additional information on how to navigate the SMV local keypad and display, refer to section 4.1, pg 23 – 25 for a basic synopsis.
If the EPM does not contain valid OEM settings, a flashing GF will be displayed when P199 is set to 1 or 2.
When P199 is set to 1, the drive operates from the OEM settings stored in the EPM Module and no other parameters can be changed (GE will be displayed if attempted)
