Setting 2: Drive dedicated motor (speed range for constant torque: 1:10)
Use this setting when operating a drive duty motor that allows constant torque in a speed range of 1:10. The drive will
allow the motor to run with 100% load from 10% up to 100% speed. Running at slower speeds with full load can trigger
an overload fault.

Setting 3: Vector motor (speed range for constant torque: 1:100)
Use this setting when operating a drive-dedicated motor that allows constant torque in a speed range of 1:100. This motor
type is allowed to run with 100% load from 1% up to 100% speed. Running slower speeds with full load can trigger an
overload fault.

Setting 5: Constant torque PM motors (constant torque range of 1:500)
Sets protection characteristics needed when driving a PM with constant torque. These motors allow for a speed control
from 0.2% to 100% when operating with 100% load. Slower speeds with 100% load will trigger overload.
