Save Config - Parker AC890 Product Manual

Performing a Rotating Autotune
Note The drive will not perform an Autotune when in Volts/Hz Mode (Open-Loop Drive.) An Autotune is not
necessary in this control mode.
Check that the motor can rotate freely in the forward direction. Ensure also that the motor is unloaded.
Ideally, the motor shaft should be disconnected. If the motor is connected to a gearbox this is okay,
provided that there is nothing on the output of the gearbox which could load the motor.
1. In the QUICK SETUP menu, set MAX SPEED to the maximum speed at which you will operate the
drive in normal operation. The Autotune will characterise the motor up to 30% above this speed. If you
later wish to run faster than this, you will need to carry out another Autotune.
2. Set AUTOTUNE ENABLE to TRUE, and start the drive
Autotune (indicated by the Run and Stop led's flashing. This may take several minutes, during which
the motor will be accelerated to maximum speed and then brought to a stop. When complete, the drive is
returned to the stopped condition and the AUTOTUNE ENABLE parameter is reset to FALSE. In
Closed-loop Vector mode (with an encoder) the encoder sign has been adjusted by the Autotune feature.
