Magnetek AC Drive Parameters
With the exception of those parameters listed earlier (Magnetek Motor/Encoder Setup Over-
view on page 2-26), all Magnetek parameters should be left at default values.
Before changing any A5 Motor Menu parameters, make sure the A5 Motor ID parameter is set.
Setting Motor ID loads nominal values into select parameters in the A5 menu.
The following drive parameter table is included for your convenience and in the event the table
shipped with the controller is not available. In any case, you should use the table to verify all
settings on the elevator drive.

motor current and speed will be jittery. If too
small, the motor will be sluggish.
