Features: 
 ■ intelligent follow patterns, dramatically reducing the time taken is not valid, energy-saving effect is remarkable. 
 ■ optimal pump operation, precise control of downtime, improve production. 
 ■ safe, reliable and reduce the mechanical systems and piping failures, increase system reliability and stability. Extend equipment life, reduce maintenance costs. 
 ■ does not produce any harmonics and reduce the motor's own heat, vibration, noise and ferromagnetic losses, improve the motor operating conditions and grid voltage quality. 
 ■ High-performance programmable logic controller PLC, automatic decision-making mode, automatically follow changes in oil policy-making operation mode, the motor automatically adjusts the input voltage and current. 
 ■ Soft start and soft stop with advanced soft-start and soft stop function, effectively reduce the impact and hydraulic hammer effect. 
 ■ failure bypass system.
