Parker Hannifin expands AC30 series of variable speed AC drives

Engineered specifically for flexibility, simplicity and reliability, Parker Hannifin’s AC30 series of variable speed AC drives has been extended to cover the range from 0.75 kW to 75 kW and is also available with a pulse encoder feedback option, bringing closed-loop capabilities to the drive. Now offered in five different frame sizes, the AC30 drive provides users with exceptional levels of control, from simple open-loop pumps and fans through to closed-loop process line applications. In fact, wherever reliable and accurate motor speed control are the key requirements.

AC30 variable speed drives give comprehensive and cost effective control of either AC induction or permanent magnet (PMAC) servo motors. Importantly, the extended range features the introduction of an optional pulse encoder feedback module, which allows users to run the drive in closed-loop control rather than open-loop. This provides optimisation in highly dynamic applications, such as winding and cranes, where the speed or torque of the motor requires accurate control.

Featuring integrated energy monitoring functionality, the AC30 series facilitates the matching of motor speed to varying application demands, thus supporting the reduction of energy consumption. This not only saves money, but extends the mechanical life of motors, pumps, fans and ancillary equipment such as ducting or pipework.

Despite its simple design, there is no compromise on functionality with the extended AC30 drives. For instance users can take advantage of integrated macros for a range of applications and the Codesys-based Parker Drive Developer (PDD) software tool enables them to create sophisticated PLC functionality within the drive that would previously have required a separate PLC. Furthermore, its flexible and highly modular construction enables a wide range of communications, such as Profinet, Profibus and EtherCAT to be added easily as required, along with I/O modules.
