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 0.75 to 1000kW and
220V-240V 0.75 to 55kW.
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 modelling the
motor.
