The AC690+ series is a single range of AC drives designed to meet the requirements of all variable speed applications, from simple speed control with a single motor to the most sophisticated integrated systems with multiple drives. At the heart of the AC690+ is a highly advanced 32-bit microprocessor-based motor control model. This provides an exceptionally dynamic performance platform to which a host of communication and control options can be added, allowing you to tailor the drives to meet your exact needs. The AC690+ is available in 380-500 V 3-phase 0.75 to 355 kW and 220 V-240 V 0.75 to 55 kW.<\/p>\n
Drag:
The AC690+ can be configured by the user for 3 different operating modes:
- Open loop (volt\/frequency) control
This mode is ideal for basic engine speed control or for multiple engines running in parallel. The quick menu and clear display ensure the fastest, easiest and trouble-free start-up.
- Sensorless vector control
High starting torque and accurate speed control are ensured by a sophisticated motor control strategy MRAS (Model Reference Adaptive System). MRAS provides accurate speed simulation (without the need for a speed measurement sensor) by continuously modelling the motor.
- Closed-loop vector control
Full closed loop flow vector performance can be achieved with the AC690+ by simply adding an encoder feedback \"technology box\". This provides 100 % of continuous standstill torque at full load plus a highly dynamic speed loop (bandwidth up to 45 Hz); more than enough for the most demanding applications.<\/p>\n
