Регулирование вплоть до нулевой скорости без энкодера.
Минимум усилий по настройке со специальным векторным управлением EZ.
Точное управление асинхронными, синхронными реактивными двигателями, двигателями с постоянными магнитами.

Cost effective network integration

Подключение до пяти Q2A с одной дополнительной картой связи.

PC configuration tools: Q2edit and Q2dev

Оптимизируйте время проектирования. Графическая среда разработки позволяет быстрее настраивать индивидуальные конфигурации. Графические средства настройки: программа Q2edit обеспечивает возможность настройки параметров и мониторинга через компьютер.

Program >> Deploy >> Go

Приводы серии Q2A можно программировать без подключения источника питания. Просто подключите привод к одному из портов USB компьютера, начните программирование и оцените простоту ввода в эксплуатацию.

6. It is not possible to purchase the Regenerative braking unit (R1000) and current suppression reactor as a separate items.

7. The maximum applicable motor output complies with 380 V motor ratings as specified in Annex G of IEC 60947-4-1. The rated output current of the drive output amps must be equal to or more than the motor rated current.

8. The maximum applicable motor output complies with 460 V motor ratings as specified in NEC Table 430.250. The rated output current of the drive output amps must be equal to or more than the motor rated current.

9. The rated output capacity is calculated with a rated output voltage of 380 V.

10. The rated output capacity is calculated with a rated output voltage of 460 V.

11. Derating may be necessary for applications that start and stop frequently.

12. Derate the drive capacity to use values to 15 kHz maximum (4002 to 4103 models), 10 kHz maximum (4140 to 4389 models) or 5 kHz maximum (4453 to 4675 models).
