Drive series

Parker Hannifin has extended its AC30 series of variable speed AC drives up to 450 kW output rating to cater for high power applications. The announcement follows a recent update to introduce a resolver feedback option, bringing further closed-loop capabilities to the portfolio.
The AC30 series is available in several different frame
sizes to suit the widest possible range of applications. High levels of control are possible, for applications ranging from simple open-loop pumps and fans to closed-loop process line applications. The series provides an accurate motor speed control of either AC induction or permanent magnet (PMAC) servo motors.
Offering integral energy monitoring capability, the AC30 series allows customers to match motor speed to fluctuating application demands. As well reduced operating costs, the mechanical life of motors, pumps, fans and ancillary equipment such as ducting or pipework, can be extended by using the AC30. In addition, a wide range of communications protocols are compatible with the drives; these include Profinet, Profibus and EtherCAT, all of which can be added easily, along with I/O modules.
