Frequency setting method

Settings can be implemented through digital, analog, pulse frequency, multi-step speed running, simple PLC, PID communication,
communication and so on.
Settings can be combined and the setting channels can be switched.

Automatic voltage regulation

The output voltage can be kept constant although the grid voltage changes.

More than 30 protection functions, such as protection against overcurrent, overvoltage, undervoltage, overtemperature, phase loss,
and overload

Speed tracking restart

Used to implement impact-free smooth startup for rotating motors

EMC filter

The transmission of the VFD meets the IEC/EN 61800-3 C3 requirements.
When optional filters are connected externally, the transmission of the VFD can meet the IEC/EN 61800-3 C2 requirements.
Note: Comply with the EMC requirements and the technical requirements for the motors and motor cables.
