Control character |
Control mode | V/F Control | |
| Freq. Setting resolution | Analog terminal | 0.1% of max output frequency | |
| Digital setting | 0.*1Hz | ||
| Panel analog setting | 0.4 % of max frequency | ||
| External pulse | 0.1% of max frequency | ||
| Freq. accuracy | Analog Input | Within 0.2% of max. output frequency | |
| Digital Input | Within 0.*1% of setting output frequency | ||
| External pulse | Within 0.1% of max. output frequency | ||
|
V/F Curve (Voltage-Frequency character) |
Base frequency can be set from 5~**0Hz arbitrarily, and there are three kinds of curve: constant torque ,Dec torque 1 and Dec torque 2. | ||
| Torque Boost | Manual Setting: 0~*0% of rated output, Auto-boost: Automatically boost torque according to output current. | ||
| Auto Energy-saving running | Adjust output voltage and slip compensation properly according to output current, which will make the motor working in highest efficiency. | ||
|
Control character |
Acc./Dec time setting | 0.1~***0 seconds can be set continuously, and S type and line type can be selected. | |
| Braking | Dynamic braking | Over *5% (External braking resistor) | |
| DC braking | It is selected respectively at start and stop, and its frequency is 0~*5Hz, the action voltage is 0~*5%, and the action time is 0~*0.0 second or act continuously. | ||
| Auto current-limiting function | Fast auto current-limiting function ensures not to occur the over-current during the accelerate process or under the impact load. | ||
| Overvoltage prevention | Ensure not over-voltage in Dec process. | ||
| Low noise running | Carrier freq. can be adjusted continuously form 1.5KHz to *5.0KHz, which can reduce the motor’s noise furthest. | ||
| Speed tracking restart | It can realize the smoothness restart and instantaneous stop then restart function. | ||
|
Freq. setting signal |
Analog | DC voltage 0~*0V,**0V~*0V, DC current 0~*0mA ( Upper limit and Lower limit can be selected ). | |
| Digital setting | By the running panel | ||
| Pulse | 0~*0kHz (Upper limit and Lower limit can be selected) | ||
| Startup signal | FWD, REV, startup signal can be selected and self-keep (Three line control). | ||
| Timer and Counter | Embedded one timer and one counter ,which will help the system’s integration. | ||
|
Multi-speed control
function/ Wobble frequency |
Seven steps programmable multi-speed control at most, every step’s running direction, running time can be set respectively. In external terminal control, It reaches *5 steps, and there are 6 kind of running modes. Include wobble frequency. | ||
|
Built-in PID control |
Common PID | Expediently compose the simple control system without accessional PID controller. | |
|
Special for water
supply (Need accessories) |
Make it possible to construct the constant-pressure water-supply system of 4 pumps switch at most, which includes the following functions: pressure upper or Lower limit alarm, Sleep or wake, Timing water-supply etc. multi kind running mode. | ||
| Running function | Setting the upper and lower limit of frequency, frequency jump-running, reversal running limit, slip frequency compensation, auto constant-voltage running, RS**5 communication frequency increment and decrement control, fault self-restore running, multi inverter coupled running. | ||
| Output signal |
Running status (OC Output) |
During the running of inverter, frequency arrival, frequency level detection, over-load alarm, and external fault stop-machine. Frequency upper-limit arrival, Frequency lower-limit arrival, under-voltage stop, zero-speed running, programmable multi-speed running state, Internal counter arrival, Internal timer arrival, Pressure lower-upper limit alarm. | |
| Output signal | Indicating meter | Output Freq., output current, output voltage, motor speed, PID setting and feedback, external voltmeter, external cymometer. | |
| Display |
Running panel display |
Running status | Output Freq., output current, output voltage, motor rotate speed, setting frequency, PID setting, PID feedback, model temperature, accumulative running time, analog I/O, terminal Input status. |
| Alarm content | Last six fault records, output frequency, setting frequency, output current, output voltage, DC voltage, model temperature, terminal status, accumulative running time of Last fault trip. | ||
