limitations.
When using a Permanent Magnet motor some limitations should be consid-
ered regarding application and functionallity point of view.
From application point of view take this limitations in consideration:
1. Use always on reduced torque applications with a starting torque less than
50%.
2. MX2 in PM mode is not suitable for use in constant torque application
where rapid acceleration/deceleration and low speed operation is need.
Never use for transportation machine and specially for vertical loads such
elevators.
3. Drive is able to control up to 50 times the motor moment of Inertia.
4. Two or more motors could not be driven with one inverter
5. Be careful not exceed the demagnetization current of the motor
From functionality point of view several functions and parameters are not
available when PM mode is selected, next table show which ones.
