IONI device model comparison
The main difference between IONI and IONI Pro is that Pro model will get more advanced functions as downloadable upgrades. The planned additions are:
- Notch filter for advanced vibration damping
- Support for EtherCAT field bus (through separate EtherCAT to SimpleMotion V2 bridge device)
- True dual-loop feedback position control
- SinCos 1 Vp-p encoder support
- Serial encoder support (TBD)
 | The above list is preliminary and subject to change. For realized differences, see comparison below. |
