SynRM20 - для управления синхронным реактивным двигателем
Тип:Частотный преобразователь
SynRM20 Приводы синхронных реактивных двигателей (СРД)  — интеграция концепции управления синхронными реактивными двигателями и разработка нового алгоритма векторного управления. Сделал совершенно новый наблюдатель потокосцепления. Он имеет превосходный эффект управления в чистом синхронном реактивном двигателе и вспомогательном синхронном реактивном двигателе с постоянными магнитами и обеспечивает высокую надежность, высокую стабильность и высокую адаптируемость приложений с синхронными реактивными двигателями.

Onboard Multiple preset speeds It implements up to 16 speeds via the simple PLC function or by control terminal
Onboard  PID It realizes process-controlled closed loop control system easily.
Auto voltage It can keep constant output voltage automatically when the mains voltage changes.
regulation (AVR)
Over-voltage/ The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to over-voltage/over-current.
Over-current stall control
Torque limit and torque control It can limit the torque automatically and prevent frequent over-current tripping during the running process.
Instantaneous stop doesn’t stop The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time.
Rapid current limit It helps to avoid frequent over-current faults of the AC drive.
High performance Control of asynchronous motor is implemented through the high-performance current vector control technology.
Timing control Time range: 0.0–6500.0 minutes
