Function Description
Servo/stepping 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.
  • 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)
  • Stepping motor, 2 phase (4,6 or 8 wires)
Control modes
  • Torque control
  • Velocity/speed control
  • Position control
Setpoint types

See setpoint signal / reference inputs list

Closed loop Cascaded control loops (PIV):
  • Torque / current control, update frequency 20.0 kHz
  • Velocity control, update frequency 2.5 kHz
  • Position control, update frequency 2.5 kHz
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)
Feedback devices
  • Quadrature (incremental) encoders
Safety
  • Safe torque off with 3-way redundancy
  • Charge pump enable input
  • 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
Power supply
  • Externally supplied 12 – 49 VDC
  • Single power supply operation mode, no separate power supply needed for logic
Motor output current 1
  • AC/BLDC/Stepping/Linear motors (current specified as peak of sine):
    • 0 - 8 A
  • Brush DC motors:
    • 0 - 10 A
Commissioning
Compliance CE (LVD & EMC): EN 61800-5-1:2007, IEC 61000-6-1:2005 and IEC 61000-6-3:2006.

Notes:

  • The device is Low Voltage Directive (LVD) compliant up to 42 VDC power supply, and above that level the supply voltage is considered hazardous, so external measures (such as or isolation or protective impedance) are necessary to prevent human contact to any circuit connected to the device.
  • In order to meet EMC standard requirements, a proper installation and wiring is necessary. Refer to user guide for proper installation.
Reliability
  • MTBF: TBD

1) Currents achievable continuously only with with sufficient coolant air flow. Without forced cooling, typically 30-45% of the maximum range can be driven continuously. Despite of this, maximum current is available for short periods of time even without cooling. Current is automatically throttled on temperature rise to protect the drive.
