Can you use the Energy Savings (nLd) motor control type on the ATV930 drive run a constant torque load like a grain leg?
Issue:
Apply nLd energy savings motor control type on a ATV930 to run at constant torque load.
Product Line:
ATV930 in nld motor control type nld
Environment:
All
Cause:
NA
Resolution:
No, nLd control law is not recommended for constant torque or heavy duty applications.
Constant torque or Heavy Duty applications will rarely operate in a condition where the drive is able to reduce the motor current, and using this mode may result in poor speed/torque regulation in those applications.
This mode is primarily intended for fan or pump loads.
