AC890PX AC Drive
Performing a Stationary 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.
Before starting the stationary Autotune, you MUST enter the value of magnetising current for the motor. This may be
available on the motor nameplate. If not, you may need to contact the motor supplier.
1. In the QUICK SETUP menu, set the AUTOTUNE MODE parameter to STATIONARY (0).
2. Set ENABLE to TRUE, and start the drive . The drive will carry out a stationary Autotune, injecting current into the
motor but not turning the shaft. The Run and Stop led’s will flash. When complete, the drive is returned to the stopped
condition and the AUTOTUNE ENABLE parameter is reset to FALSE.
IMPORTANT Now perform a SAVE CONFIG to save your new settings. Refer to Chapter 7: “The Keypad” - Quick Save Feature.

If the drive is configured to run in Sensorless Vector mode, set-up is complete.

If the drive is configured to run in Closed-loop Vector mode, i.e. using an encoder, then the encoder direction must be set
up. Refer to “Setting the Encoder Sign” below.
