5.8 L: Protection Functions
Setting 3: Vector m otor (speed range fo r constant torque: 1:100)
Use this setting when operating a drive-dedicated motor that allows constant torque in a speed range o f 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.
