MH300 high end series, owns two control models: open-loop&closed-loop vector control with high performance and best price that can drive asynchronous motor and synchronous PMSM ac motor(MH300P series).

Rich Extensibility&Terminals: there are different extended cards for I/O point, CAN, Profibus and PLC. And various PG cards are provided for closed loop vector control.

Product Components and Independent air fule: strong anti-interference power mainboard; infineon IGBT module with strong overload capability; indepent air fule prevents dustry entering and decreases temperature rise.

Drive asynchronous motor and PMSM synchronous motor without encoder(MH300 series with self-tunning function ) with high rotating speed and wide speed range: SVC is with ±0.5% rotating speed, 1:100 speed range, <20ms torque response; FVC is with ±0.2%, 1:1000 and <2ms.

Instant stop Non-stop Function&Overexcitation Braking Function: When instantly powers off or accidently voltage drops, frequency converter will low output speed and feedback power through load to guaranteen itself run in short times. Overexcitation braking function can effectively inhibit Bus voltage increasing to avoid frequent fault alarms, and realize fast braking.

Excelent Side Wave&Multi Motors to Switch: MH300 series owns excelent side ware to meet one-driven-multi and long distance application. It supports four motors' parameter that realize the switch asynchronous motor and synchronous PMSM AC motor.

Bulit-in Simple PLC to realize cycle operation at Max 16-segment constant time and speed.

Pendulum Frequency Function &Vitual I/O: pendulum frequency function can improve colling's densityin textile and chemical fiber manufacturing industry; Through easy setting, inner logic control function can be customized.

♥ The avaliable voltage specifications are: 3 phase 380vac input output, 3phase 220vac input output, 1phase 220vac input 3phase 220vac output.

♥ Frequency converter can not be used as voltage inverter or converter. But its input voltage can be DC(±15% DC540V for 3phase 380V devices, ±15% DC310V for 3phase 220vac devices).

Q1. What information should be provided to get a clear model with quotaion?

Please directly provide input output voltage, power, applied machine, specific requested function in inquiry. 

Q2. They have EMC filter in the standard version? In option?

EMC filter is option (under 7.5kw, EMC is bulit-in; >7.5kw, EMC filter is external).

Q3. They have input DC or AC REACTOR? In option?

Both of input and output reactor is external and option. And there is a bulit-in DC reactor within VFD, but this reactor is to protection internal electric components; 

Q4. They have a PID control? Multiple PID control references?

Yes, there is one road PID control with two parameter groups, this means two different parameter setting can be configured and switched to each other. Multiple PID is multi road PID control, or multi PID control groups? 

Q5. What is the maximum wiring distance between the output and the motor in the standard version?

There are three options for different sites: - ≤20m, VFD and motor can be directly connected; -20m 100m, VFD and motor can be dirctly connected, except adjust carrier frequency, still need to add output AC reactor;

Q6. What is the minimum value of the power factor?

The Maximum power factor is 0.95  (the better, the bigger power factor ). But the final power factor is depens on load type and motor's power factor. If motor's power is too little, VFD still can not make better power.
