|
|
Onboard Multiple
Preset Speeds
|
It implements up to 16 speeds via the simple PLC function or combination of X terminal states
|
|
|
Onboard PID
|
It realises process-controlled closed loop control system easily.
|
|
|
Auto Voltage
Regulation (AVR)
|
It can keep constant output voltage automatically when the main voltage changes
|
|
|
Overvoltage/
Overcurrent Stall
Control
|
The current and voltage are limited automatically when the main voltage changes
|
|
|
Torque Limit and 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
|
|
|

Digital analog voltage, analog current, pulse, serial port can be switched by many ways
|
|
|
Auxiliary Frequency Source
|
10 kinds of frequency source, can easily realise Micro adjustment, frequency
|
|
|
Input and Output
|
Input Terminals
|
6 digital input terminals, one of which supports up to 100kHz high-speed pulse input.
