It has superior performance and rich functions with elegant appearance; heat dispersion is good, and the volume is smaller with a more reasonable design; the configuration is flexible that it can meet different demands of customers.

     Product features

• Two control modes:non-PG vector control(SVC),V/F control
• Multistage V/F curve setting function
• Pull-in torque:non-PG vector control(SVC)0.5Hz could reach 150%
• Internally installed PID control function that could implement close-loop constant temperature and constant voltage control.
• Multiple frequency setting is supported:digital set, analog quantity set, PID set, RS485communication set.
• Free programming is available for I/O terminal  and could combine various work patterns according to users’ need.
• 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.
• Detection function for torque rich and less torque.
• Switch function of main and auxiliary frequency,  run command, and on the spot and long-distance.
• 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.
• 0.75~15kW internally installed brake unit. It just needs to add a brake resistor to implement fast stop.
• Higher than 7.5kW.  Internally installed trace function of revolving speed that could realize shock-free smooth start to the rotating motor.
