Tips and Tricks for the AKD Performance Servo Tuner (Autotuner and Bode Tool)


Increase the Excitation Current

If the excitation current is too low, the motor will not be able to move enough to measure a good frequency response.  If the autotuner fails to complete because of not moving enough, then increase the excitation current.  Set the excitation level to “Manual” and enter a higher current amplitude.

Taking a bode plot for tuning analysis



  1. Put the drive in Torque mode.
  2. Leave the excitation level set to “Automatic”.
  3. Set the Performance Servo Tuner mode to “Bode Plot”. 
  4. Set the measurement to “Plant”.
