The SA3100 series drives offer three control modes to match application requirements. V/Hz control is suitable for basic fan and pump applications. Sensorless vector control provides high torque at low speeds without feedback devices. Closed-loop vector control with encoder feedback delivers precision speed and torque regulation for demanding applications such as extruders, winders, and hoists.
The integrated LCD keypad allows local programming, monitoring, and fault diagnostics. A keypad copy function enables fast configuration of multiple drives. The built-in EMC filter simplifies compliance with electromagnetic compatibility standards. The drive includes programmable digital and analog I/O, a PID controller for process regulation, and a real-time clock for scheduled operations.
This AC drive is used in HVAC systems, pumping stations, conveyor systems, and industrial machinery. Its robust design and flexible control modes make it suitable for both constant torque (conveyors, positive displacement pumps) and variable torque (centrifugal fans, pumps) applications. The SA3100 series is commonly found in water/wastewater treatment, manufacturing plants, and commercial buildings.
