Question:
Do you have to adapt the controller settings when using new L-force high-efficiency three-phase AC motors (MHEMA, MHFMA) instead of 'old' motor types such as MDFMA?
Answer:
In most cases, the motor data of different motor types differ from each other. This is why the controller settings must be adapted accordingly.
For controllers parameterised using Global Drive Control (GDC) (9300, ECS, 8200), use the 'Input assistant for motor data' (top right motor symbol button) to enter the motor data. The latest GDC version also contains the new high-efficiency motors (MHxMA).
For the controller series (9400, 8400) parameterised using the 'Engineer' PC tool, also use the motor data input dialogs to adapt the motor data. The latest catalogs in the Engineer contain the new high-efficiency motors (MHxMA).
Speed controller, position controller - adjustment required:
The input assistant for motor data also sets the controller settings for the speed and position controller to the Lenze settings which differ from motor type to motor type.
Due to the operating principle, the speed and position controller settings always depend on the combination of motor and load mechanism (the controlled system).
--> For this reason, these settings always must be adapted individually if the operation with the Lenze settings does not meet your expectations.
Tip for practical operation:
When changing to another motor type with nearly the same rated data like the type used before, you can usually use the same controller settings as before.
Current controller settings – in most cases, no adjustment required:
The current controller settings mainly depend on the electrical motor and controller data. Use the input assistant for motor data to select current-controller settings matching the motor. The settings usually no longer need to be adjusted.
