通用型高性能交流驅(qū)動器： AC650V系列 AC650V在AC650上進行了擴展，增加了無傳感矢量控制。適用于需要提升負載變動下的速度調(diào)節(jié)和大慣量系統(tǒng)的高起動轉(zhuǎn)矩需求應(yīng)用。 離心泵 工業(yè)鼓風(fēng)機 攪拌機 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.
