Issue:
The actual value does not match the analog output of the drive.

Product Line:
Altivar Machines

Environment:
All models and serial numbers

Cause:
The most common cause is that the maximum frequency (tFr) is not set the same as the high speed (HSP) setting.

Resolution:
The analog output is based off of the maximum frequency setting.  The default maximum frequency is set at 20% above the standard motor frequency (bFr).  If the bFr is 60 the tFr is 72.  Changing tFr will cause the analog output to match the actual value.
