Parker Hannifin’s AC30 series of variable frequency drives has been extended to cover the range from 1 HP to 100 HP and is now available with a pulse encoder feedback option. Engineered specifically for flexibility, simplicity and reliability, the AC30 VFD 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 provide comprehensive and cost effective control of either AC induction or permanent magnet AC motors. Importantly, the series now features an optional pulse encoder feedback module, which allows users to run the drive in closed-loop control rather than open-loop. This provides optimization 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 reducing energy consumption. This not only saves money, but can extend the mechanical life of motors, pumps, fans and ancillary equipment such as ducting or pipework. Standard conformal coating provides protection in harsh environments.

Despite its simple design, there is no compromise on functionality with the extended AC30 drives. Application macros are provided for situations requiring pre-defined functions like PID control, pump control, fan control, or preset speeds. Furthermore, its flexible and highly modular construction enables a wide range of communications, such as Ethernet/IP, CANopen, Profinet, Profibus-DP and EtherCAT to be added easily as required, along with I/O and real time clock modules. Parker PDQ drive configuration software is provided free of charge, and an SD memory card slot on the drive simplifies firmware upgrades and allows drive configuration and data to be easily stored.
