IONI device model comparison
From Granite Devices Knowledge Wiki
The main difference between IONI and IONI Pro is that Pro model will get more advanced functions as downloadable upgrades.
- Already implemented features available exclusively on IONI Pro
- SinCos 1 Vp-p encoder support
- The planned future 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
- Serial encoder support (TBD)
 | The above list is preliminary and subject to change. For realized differences, see comparison below. |
Comparison
IONI Pro supports higher encoder resolutions and pulse frequencies. The table below summarizes the full list of differences currently:
| Feature | IONI | IONI Pro | IONI Pro HC |
|---|---|---|---|
| Max output current (AC/BLDC/Stepper) | 15 A | 18 A | 23 A |
| Max output current (Brush DC) | 19.5 A | 23.4 A | 30 A |
| Supply voltage range | 5-52 VDC | 5-52 VDC | 5-55 VDC |
| Max encoder count rate | 0-4 MHz | 0-18 MHz | |
| Encoder resolution | 100-65535 P/R | 100-15000000 P/R | |
| Pulse/dir setpoint frequency | 0-4 MHz | 0-8 MHz | |
| Quadrature setpoint frequency | 0-1 MHz | 0-2 MHz | |
| SinCos encoder support | No | Yes, selectable resolution interpolation factor 16X, 64X or 256X | |
| Motor torque cogging & ripple compensation | No | Yes | |
