Issue:
Input summing used in ATV61/ATV71, the HMI is being used for the multiplier input (MA2). MFR is being reset to 100% after each power cycle.
 
Product Line:
ATV61/ATV71
 
Environment:

All models, All serial numbers
 
Cause:
Information not available in current literature.
 
Resolution:
Yes, the MFR parameter will be reset to 100% each time power is cycled.  There is no way to save the value of MFR into EEPROM memory.  To prevent this from causing a problem, try using an analog input for your multiplier instead of the HMI.
