Ready to autotune
Autotune
The drive is able to perform either a stationary or a rotating
autotune. The motor must be at a standstill before an autotune
is enabled.
To perform an autotune:
•Set Pr 38 = 1 for a stationary autotune or set Pr 38 = 2 for a
rotating autotune
• Close the drive enable signal (apply +24 V to terminal 11).
The drive will display ’rdy’.
• Give a Run command (apply +24 V to terminal 12 - Run
forward or terminal 13 - Run reverse on Unidrive M200;
press keypad Start button on M201). The display will flash
‘tuning’ while the drive is performing the autotune.
• Wait for the drive to display ‘inh’ and for the motor to come
to a standstill.
• Remove the drive enable and run signal from the drive.
Autotune complete
When the autotune has been completed,
Pr
38
will be set to 0
Tuning of frequency
controller gains
(RFC-A mode only)
Depending on the application, the frequency controller gains
(Pr
65
and Pr
66
) may need to be adjusted.
