AC690+ INTEGRATOR Series AC DRIVES
!!!OBSOLETE!!! Please consider AC30 OR 890 Series below
The AC690+ series is a single range of AC drives designed to meet the requirements of all variable speed applications from simple single motor speed control through to the most sophisticated integrated multi-drive systems.
The heart of the AC690+ is a highly advanced 32-bit microprocessor based motor control model. This provides an exceptional dynamic performance platform to which can be added a host of communications and control options, enabling you to tailor the drives to meet your exact requirements.
The AC690+ is available in 380-500V 3-phase 1 to 1500 HP and 220V-240V 1 to 75 HP.
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 ‘technology box’.
This provides 100% continuous full load standstill torque plus a highly dynamic speed loop (up to 45 Hz bandwidth) ; more than sufficient for the most demanding of applications.
