Enter:
• Acceleration rate in Pr 2.11 (SE03, 0.24) (time to accelerate to maximum
speed)
• Deceleration rate in Pr 2.21 (SE04, 0.25) (time to decelerate from
maximum speed)
Enable the
field
controller
Field controller set-up
• Select field mode by setting Pr 5.78 = IntrnL (Internal field controller is
used), Etrnl (External half control), E FULL (External in full control).
•Set Pr 5.77 (SE12, 0.33) = On to enable the field.
Static
autotune
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:
•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 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
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 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:
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 xx.00 (SE00, 0.21)
Press the red reset button or toggle the reset digital input (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
