The main difference between IONI and IONI Pro is that Pro model will get more advanced functions as downloadable upgrades.

Available exclusive IONI Pro features
  • SinCos 1 Vp-p encoder support
  • Motor torque cogging & ripple compensation
  • Notch filter for advanced vibration damping
  • Power consumption limit (useful with switch mode power supplies)
  • Homing function and soft travel limits that work in all control modes, not just position control mode
  • Torque mode effects: damping, friction and inertia (useful in simulator applications)
  • SimuCUBE simulator motherboard support
The planned IONI Pro features are

The planned features are implemented as user downlodable firmware. Firmware upgrades are free.


The table below summarizes the full list of realized differences. All base features are available in all models. For full list of features, see IONI specifications.
