Parker AC690+ AC Drives

AC Drives

Parker AC690+ Integrator Series AC Drives

The Parker AC690P Series AC Drive 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+ AC Drive 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+ AC Drive is available in 380-500V 3-phase 1 to 1500 HP and 220V-240V 1 to 60 HP, including single phase input for 1 to 3 HP.


The Parker AC690+ AC Drives can be user configured for 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.


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.


Line Regenerative
Some applications require full four quadrant operation or extensive braking capabilities. The AC690+ series offers an energy efficient alternative to dynamic braking resistors in its Active Front End (AFE) unit. The AFE allows regenerative power to be returned to the grid safely and efficiently, and at unity power factor. The AC690+ AFE can also be used for situations that require ultra-low harmonics. An AFE package is offered, complete with LCL filter and other required components. See page 35 for details.
