What can cause the analog output not to match the actual value on the Altivar drive when the analog output is set to motor frequency?
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.
