| ems | Specifications | |
| Input | Rated voltage, frequency | 380V/220V;50/60Hz |
| Permissible range of operating voltage | Fluctuation:<+20%; voltage imbalance rate:<3%; freq fluctuation:<+5% | |
| Output | Voltage | 0~380V/0~220V |
| Freq | 0.0~630.0Hz | |
| Overloading ability | 150% rated current 1min; 200% rated current 1s; 220% rated current, instantaneous trip. | |
| Main control performances and featured functions | Control mode | V/F control(simplified magnetic flux control technology)/advanced magnetic flux vector control |
| Modulation mode | Flexible PWM technology | |
| Speed range | 1:50 | |
| Startup torque | At 3.0Hz,>150% rated torque(VF control),torque response time <50mS At 1.5Hz,>180% rated torque(Advanced magnetic flux vector control),torque response time <20mS | |
| Freq accuracy | Digital setting: maxi freq ×+0.02%; analog setting maxi freq×+0.1% | |
| Freq resolution(step) | Digital setting:0.1 Hz, analog setting: maxi freq × 0.05% | |
| Torque boost | Automatically arise torque/ arise torque by hand 0.1%~30.0% | |
| V/F curve | 21 modes: linear, 2 squared characteristic curve and V/F curve with multiple dots | |
| Speed up/down curve | Linear curve speed up/down: 2 kinds of speed up/down time, longest time: 1 hour | |
| DC braking | Startup freq of DC braking:0.00Hz~maxi freq, Braking time:0.0s~30.0s, braking current: 0.0~150.0% rated current of motor | |
| Auto voltage regulation(AVR) | When system voltage change, able to keep output voltage constant automatically | |
| Compensation of rotation error | Rational setting of compensation for rotation error, can compensate the change of rotation speed due to load, to achieve higher control accuracy of speed | |
| Limit the operation current, prevent frequently tripping due to over-current | ||
| Control of over-voltage speed loss | Limit the operation voltage, prevent frequently tripping due to over-voltage | |
| Magnetic flux braking | To achieve shorter speed-down/braking time through this mode | |
| Over-modulation | Utilize over-modulation technology for over the basic freq, to get higher voltage output, increase hi-freq output torque of the motor. | |
| No stop at instantaneous | When voltage fall down at short time, it can keep inverter busbar voltage constant, to avoid tripping. | |
