|
Built-in simple PLC, multiple speeds
|
It realizes up to 16 speeds via the simple PLC function or
combination of DI terminal states
|
Built-in PID
|
It realizes closed loop control system easily
|
Auto voltage regulation (AVR)
|
It can keep constant outputvoltage automatically when the mains
voltage fluctuation.
|
Overvoltage/Over current stall control
|
The current and voltage are limited automatically during the
running process so as to avoid frequently tripping due to
overvoltage/over current.
|
Rapid current limit function
|
It can auto limit running current of frequency inverter to avoid
frequently tripping
|
Torque limit and control
|
(Excavator characteristics) It can limit the torque automatically
and prevent frequently over current tripping during the running
process. Torque control can be implemented in the VC mode
