For example, the drives include an auto-tuning sensorless vector mode, which takes them beyond simple V/Hz motor control and allows users who need dynamic speed or torque control for their applications to benefit from the drives’ 0.5% speed and 5% torque accuracies.
The drives, which operate from three-phase 400V supplies, provide output frequencies up to 650Hz, and can handle 150% overloads for 1 minute. They have integrated keypads and have been designed to reduce the time and effort required for installation, set-up and commissioning. Parker says that typical applications will include conveyors, centrifuges, fans, mixers, packaging machines and textile machines.
The energy-saving drives incorporate conformally-coated PCBs, allowing them to withstand arduous environments in which many other microdrives would struggle.
The AC10 drives will be available on 24-hour deliveries.
• At the SPS show, Parker also announced extensions to its AC30 general-purpose drive range, which now includes ratings up to 75kW. The company is looking to extend the top rating up to 150kW. It has also added a new encoder feedback option for closed-loop applications.
