Freq Reg We BW
Sets the electrical (stator) frequency bandwidth for the Frequency Regulator, which
estimates motor speed when sensorless feedback is selected.
Must always be set to a value higher than Par 475 [Freq Reg Wr BW].

Freq Reg Wr BW
Sets the rotor (speed) frequency bandwidth for the Frequency Regulator, which estimates
motor speed when sensorless feedback is selected.
Must always be set to a value higher than Par 97 [Act Spd Reg BW]. Normal applications
should use a value approximately 50% greater than Par 97. Applications with large
dynamic ranges can use values 200-300% greater than Par 97. However large values
can result in pull-outs and unstable operation.

Motor Ctrl Mode
Enter a value to select the operating mode for the Motor Control (MC).
• 0 “FOC” - (Field Oriented Control) is induction motor control with voltage adaptation.
• 1 “FOC 2” (Field Oriented Control 2) is induction motor control with temperature
adaptation.
• 2 “Pmag Motor” - (Permanent Magnet Motor Control) is permanent magnet motor
operation.
• 4 (Test) - Is the test mode.
