Three-phase 380~460 VAC, allowable fluctuation range: -15%~+10% (323~506VAC) |
| maximal frequency | Vector control: 0.00~500.00Hz |
| carrier frequency | The carrier frequency can be automatically adjusted according to the load characteristics from 0.8kHz to 8kHz |
| Frequency command | Digital setting: 0.01Hz |
| control method | Open loop vector control (SVC) |
| pull-in torque | 0.25 Hz/150%(SVC) |
| Speed range | 1:200(SVC) |
| Steady speed accuracy | ±0.5%(SVC) |
| Torque control accuracy | SVC: above 5Hz ±5% |
| Torque increase | Automatic torque increase, manual torque increase 0.1%~30.0% |
| Acceleration and deceleration curves | Linear or S-curve acceleration and deceleration mode; four kinds of acceleration and deceleration time, the range of acceleration and deceleration time 0.0~6500.0s |
| DC injection braking |
DC braking starting frequency: 0.00Hz~maximum frequency; braking time: 0.0s~36.0s; braking action current value: 0.0%~100.0% |
| electronic control | Point motion frequency range: 0.00Hz~50.00Hz; point motion acceleration and deceleration time: 0.0s~6500.0s |
| Simple PLC, multi-speed operation | Up to 16 segments of speed operation can be achieved through the built-in PLC or control terminal |
| built-in PID | It is convenient to realize the closed-loop control system of process control |
| Automatic voltage regulation (AVR) | When the grid voltage changes, it can automatically maintain the constant output voltage |
| Overvoltage and overloss rate control | Automatic current and voltage limitation during operation to prevent frequent overcurrent and overvoltage faults |
| Fast current limiting function | Minimize the overcurrent fault and protect the normal operation of the inverter |
| Torque limitation and control |
The “excavator” feature automatically limits the torque during operation to prevent frequent overcurrent faults: vector control mode can achieve torque control |
| It’s a constant stop and go | In the case of instantaneous power failure, the energy feedback from the load compensates for the voltage drop and maintains the inverter running for a short time |
| Fast flow control | Avoid frequent overcurrent faults in the frequency converter |
| Virtual l0 | Five sets of virtual DIDO can realize simple logic control |
| timing control | Timer control function: set the time range 0.0min~6500.0min |
| Multiple motor switching | Two sets of motor parameters can realize the switching control of two motors |
| Multithreaded bus support | Support a fieldbus: Modbus |
| Powerful background software | Support the inverter parameter operation and virtual oscilloscope function; through the virtual oscilloscope can realize the internal state monitoring of the inverter |
