Is the FM terminal output signal (0-10Vdc) linear to motor load when FMSL=1?

Published date: 26 February 2019

Issue:
Was wondering if the FM terminal output signal (0-10Vdc) linear to motor load when FMSL=1?

Product Line:
ATV212

Environment:
All serial numbers

Cause:
Customer wanted to set FMSL=1 on the ATV212 drive.

Resolution:
It's better to set FMSL=8 to have a linear relation between Analog output and load.  If FMSL=1, then torque current is depended on the load, and fluxing current is depended on the motor.
