Static autotune
Quantum MP is able to perform either a static, rotating or continuous autotune. The motor must be at a
standstill before an autotune is enabled.
Static autotune for current loop gains
When this operation is performed the drive will perform an estimation of Motor constant (Pr 5.15), Continuous
proportional gain (Pr 4.13), Continuous integral gain (Pr 4.14), Discontinuous integral gain (Pr 4.34), Back
EMF set point (Pr 5.59), Armature resistance (Pr 5.61) and Flux loop I gain (Pr 5.72) with respect to the
selected motor map and store the values.
To perform a static autotune:
•Set Pr 5.12 (SE13, 0.34)= 1
• Close the Drive Enable signal (terminal 31). The drive will display ‘rdY’
• Close the run signal (terminal C8). The lower display will flash ‘Auto’ and ‘tunE’ alternatively, while the
drive is performing the autotune
• Remove the enable signal when the autotune has finished
A rotating autotune Pr 5.12 (SE13, 0.34) = 2 should not be carried out when the field controller is in
voltage mode. Pr 5.75 = On (USA default)
Checking speed
feedback
• Close the enable signal. Close the run signal (terminal C8). Provide speed reference to run the drive up to
a low speed, the drive will regulate its own estimated speed
• Check that the feedback device is functioning correctly:
For encoder speed feedback - Check encoder speed feedback Pr 3.27 (Fb09, 0.79).
For tachometer speed feedback - Check tachometer speed feedback Pr 3.52 (Fb04, 0.74)
• When the feedback device being used is seen to be functioning correctly, stop the drive and select the
correct feedback device using Pr 3.26 (Fb01, Pr 0.71)
Save parameters
Select SAVE in Pr 1.00 (SE00, 0.21)
Press the red reset button or toggle the reset digital input (terminal C14) (ensure Pr xx.00 (SE00, 0.21)
returns to ‘no Act’)
Run
Drive is now ready to run
• Close enable signal
• Close run signal
• Provide speed reference
