Auto-Tuning features optimize drive parameters for operation with induction motors as
well as synchronous motors to achieve the highest performance levels possible.
Optimizing not only the drive and motor performance, but also automatically adjusts
settings relative to the connected machinery.
New Auto-Tuning methods.
A1000 continuously analyzes changes in motor characteristics during operation for highly
precise speed control.
Tuning the Motor
Rotational Auto-Tuning
Applications requiring high starting torque, high speed,
and high accuracy.
Stationary Auto-Tuning
Applications where the motor must remain connected to
the load during the tuning process.
Line-to-Line Resistance
Auto-Tuning
For tuning after the cable length between the motor and
drive has changed, or when motor and drive capacity
ratings differ.
Energy-Saving Auto-Tuning For running the motor at top efficiency all the time.
New Auto-Tuning Features
Powerful torque at 0 Hz, without sensors or feedback devices.
Until recently, sensorless control has been out of reach for synchronous
motors. Now A1000 provides powerful starting torque algorithm without
relying on pole sensors or motor feedback.
High-performance current vector control achieves powerful starting torque with an
induction motor.

Tuning the Load
ASR*Tuning
Perfects responsiveness relative to the machine.
Until now, this tuning procedure was fairly time
consuming to set.
Inertia Tuning
Optimizes the drive‘s ability to decelerate the load.
Useful for applications using Kinetic Energy Buffering
Function and Feed Forward functions.
