Issue:
Need to know the scale of the ATV600 and ATV900 Drives Analog output AQ1 when assigned as motor frequency.

Product Line:
Altivar Process ATV630 ATV650 ATV930 ATV950

Environment:
All

Cause:
Need to know how the analog output correlates to motor frequency.

Resolution:
The default scale is 0 - tFr (Max Frequency).
Note that the drive's High Speed Setting (HSP) may be same or different.

Example:
ATV630 has HSP = 50Hz and tFr = 60Hz.
AQ1 assigned as 4-20mA output for motor frequency.
motor frequency at 0Hz = 4mA output
motor frequency at 60Hz = 20mA output
It is a linear relationship between these endpoints.

The scaling can be changed with parameters ASL1 and ASH1.  See the Programming Manual for details.
