Internal field current output varies by frame size.
- Frame Size 1 to 8A, current controlled with field weakening
- Frame Size 2A and 2B to 10A, fixed voltage use FXM5 for field current control
- Frame Size 2C and 2D to 20A, fixed voltage use FXM5 for field current control
Optional FXM5 external field controller for field currents up to 90A
- Digital link for field control from Mentor II or Quantum III
- Standalone control mode
- Field weakening
- Field economy mode
