Set-Up Using The Sensorless Vector Fluxing Mode; The Autotune Feature - Parker 650G Product Manual

Operating the Drive

Set-up using the Sensorless Vector Fluxing Mode

The drive must be tuned to the motor in use by matching the motor parameters in the drive to
those of the motor being controlled.
IMPORTANT: You MUST use the Autotune feature.
Enter values for the following parameters.

The Autotune Feature

IMPORTANT: You MUST carry out an Autotune if you intend to use the drive in Sensorless Vector
Fluxing Mode. If you are using it in Volts/Hz control an Autotune is not necessary.
The Autotune feature identifies motor characteristics to allow the drive to control the motor.
It loads the values into the parameters below.
