The series of DZB300 general type inverter uses DSP all-digital control system, and the world leading vector control algorithm to implement high-performance and high accuracy motor drive control. When improving reliability and environmental suitability of products, which enhances usability for users and industrial specialized design.

- Two speed control modes: non-PG vector control (SVC), V/F control
   Non-PG vector control (SVC), pull-in torque: 0.5Hz could reach 150%.
- 8 speeds simple PLC function, multi speeds control and PID control
- It supports setting of various frequency: digital setting, analog quantity setting, PID setting, RS485 communication setting.
- I/O  terminal is free to be compiled. Many work patterns can be combined by users according to demands.
- It’s equipped with control function of hopping frequency, and could actively suppress mechanical resonance to make system more stable and reliable.
- It’s equipped with maintaining function in cases of instant power down so that it helps avoid influencing production caused by instant power down.
- It’s equipped with inspection function for torque rich and less torque. - Automatic voltage adjustment function that could effectively solve low frequency oscillation problem of high-power motor.
- Provide protection functions for many malfunctions: omnibearing real time monitoring and protection of overcurrent, overvoltage, undervoltage, superheat, overload, phase loss to ensure safe running.
- Internally installed electric reactor with above 37KW. It improves the power factor of input side as well as efficiency and stability of complete machine.

- 0.75-15kW internally installed brake unit
