ServoOne HF High-speed servo controller for spindles and turbo machines

The ServoOne HF belongs to the ServoOne servo controller series. The HF function package upgrades the ServoOne product range to a high-speed servo controller with a power range of 4 to 400 A. The high-speed servo controller is therefore ideally suited for spindles and turbo machines. The main feature of the ServoOne HF servo controller is the maximum rotary field frequency of 1600 Hz at clock rate changeover of up to 16 kHz.

With the ServoOne HF servo controller the user can configure and commission his optimal drive solution even more easily and quickly despite extended functions and extensive system components.

The HF function package upgrades the ServoOne product range to a high-speed drive controller with a power range of 4 to 400 A. The product range is available in the following versions:

  • ServoOne single-axis system for medium and large outputs with AC power supply from 1/3 x 230 V to 3 x 480V
  • Also as a DC-powered multi-axis system with sinusoidal regenerative supply units from 26 – 360 kW
  • Stackable housing with air cooling and alternatively with water cooling from 16 A
  • All field bus and technology options from ServoOne can be used and programmed in accordance with IEC 611311 for flexible and easy application settings
  • High clock rate of up to 16 kHz for low current distortions and motor losses
  • Optimized fast current controller for regulating low-inductance motors
  • Sinusoidal filers and output chokes are taken into account in the closed loop
