Further Details: The AC690+ is available in 380-500V 3-phase 1 to 1500 HP and 220V-240V 1 to 75 HP.

Features :
The AC690+ can be user configured for 3 different modes of operation:

Open-loop (volts/frequency) control
This mode is ideal for basic motor speed control, or multiple motors driven in parallel. The quick set-up menu and plain language display ensures the quickest and easiest, trouble free start up.

Sensorless vector control
High starting torque and tight speed regulation is provided by a sophisticated MRAS (Model Reference Adaptive System) motor control strategy. MRAS provides accurate speed simulation (without the need for any speed measuring transducer) by continually modeling the motor.

Closed-loop vector control
Full closed-loop flux vector performance can be achieved with the AC690+ by simply adding an encoder feedback.

This provides 100% continuous full load standstill torque plus a highly dynamic speed loop
