  • The characteristics of last generation QS6 servo drivers have been fully retained.
  • AC sine wave control, smooth torque, no impulse.
  • 2500 line incremental photoelectric encoder, high positional accuracy, rotation positional accuracy can reach 1/10000R.
  • Speed ration can be as large as 1:5000, has stable torque characteristics from low speed to high speed.
  • Adopting high speed FPGA processing, motor fastest rotation speed can be 5000RPM.
  • Rich and complete parameter setting can be configured with different ways of working and operating characteristics to adapt to different requirements.
  • Possess position, speed and torque control mode, has applications in a wide range.
  • Use intelligent Space Vector control (SVPWM), has much larger torque and much less noise than traditional SPWM.
  • Up to three times overload design, stronger load ability.
  • Perfect protection function: over current, overvoltage, over heat, encoder abnormal etc.
  • Perfect condition monitoring function, such as positional deviation, rotate speed, feedback impulse, command impulse etc.
