Issue:
With the analog signal FnSL set at 7, estimated motor torque, how can you tell what the scaling of the analog output is?

ATV212, Altivar 212, S-Flex

Environment:
Altivar

Cause:
Customer needs to know what the scaling factors are.

Resolution:
The base torque value is calculated from the drive HP size and setting of parameter F417 (Rated motor Speed or RPM).
The calculation is Motor HP * 5250 / RPM.

For example, a 10HP drive with 1750RPM.  10*5250/1750 = 20lb-ft or torque.
This means that 100% of the estimated torque is 20 lb-ft.
Since the scaling of the analog output when set to torque is 0-250% of the rated motor torque, the analog output will be scaled 0 to 50 lb-ft.
