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 any autotune is enabled and disconnected from the load for a rotating
autotune.
To perform an autotune:
•Set Pr38 = 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 or terminal 31 and 34 on
Unidrive M300). The drive will display ‘rdy’.
• Give a Run command (apply +24 V to terminal 12 - Run forward or terminal 13 -
Run reverse on Unidrive M100, M200 and M300; press keypad Start button on M101
and 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.
