Function Description
Servo motor drive Closed loop control of various types of servo motors by sinusoidal field oriented control with dead-time distortion correction and high dynamic range torque control.
  • Support over 97% of all the servo motors below 2 kW in the market
  • Synchronous AC & BLDC motors
    • Sinusoidal and trapezoidal commutated
    • SPM (Surface Permanent Magnet) and IPM (Internal Permanent Magnet) types
  • Brush DC motors
  • Linear motors
    • Iron core
    • Ironless (with external inductive filter)
Control modes
  • Torque control
  • Velocity/speed control
  • Position control
Closed loop Cascaded control loops (PIV):
  • Torque / current control, update frequency 17.5 kHz
  • Velocity control, update frequency 2.5 kHz
  • Position control, update frequency 2.5 kHz

Dual-loop feedback support planned as firmware upgrade

Feed-forwards Feed-forwards working in velocity & position control modes:
  • Acceleration (inertia canceling) feed-forward
  • Velocity (friction canceling) feed-forward
Homing Integrated homing function for position control mode:
  • Sensorless hard-stop homing
  • Home switch search
  • Index pulse search
  • Soft position limits (eliminate limit switches)
Setpoint signal See setpoint signal / reference inputs list
Feedback devices See feedback devices list
Safety
  • Safe torque off with 3-way redundancy
  • Stopping motor on errors
    • Tracking error (velocity & position)
    • Over speed error
    • Limit switch
  • DC motor runaway prevention on feedback loss
  • Communication error detection
Protections
  • Over current
  • Short circuit (phase-to-phase)
  • I2t motor thermal protection
  • Over & under voltage
  • Over temperature

Approvals CE (LVD & EMC)
