Running
control
performance
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.
Fault protection
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
Note:
The function is available only for 004G/5R5P
and higher models.
