controller
• Set Pr 5.77 (SE12, 0.33) = On to enable the field.
Mentor 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:
Static
• Set Pr 5.12 (SE13, 0.34)= 1
autotune
• Close the Drive Enable signal (terminal 31). The drive will display 'rdY'
• Close the run signal (terminal 26 or 27). 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
• Remove the run signal
NOTE
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).
• Close the enable signal. Close the run signal (terminal 26 or 27). 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:

• 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).
