IONI is a digital motor drive designed for driving AC/BLDC and DC servo motors and steppers. IONI allows controlling motors in all three operating modes: position control, velocity control and torque control (torque mode only with servo motors). Applications of such control methods include
- Position control, such as CNC, robotics and 3D printing
- Velocity control, such as spindles or feeders
- Force / torque control, such as racing simulator wheel
Commands to IONI drive can be delivered in many formats and from many sources, such as PC, PLC, microcontroller (i.e. Arduino, MBED and OEM boards) or embedded computers like Raspberry Pi. IONI understands several forms of setpoint commands:
- Step & direction digital signals (typical stepper drive interface, good for position control)
- Analog +/-10V signal (good for speed or torque control)
- PWM signal (good for speed or torque control)
- RS485 serial bus (talks SimpleMotion V2 bus protocol, open source library available)

Supported motors
As motor is not included, make sure that you have, or obtain a motor that is compatible with IONI. Learn more about motor types.
Servo motor requirements
- Permanent magnet brush-DC, AC, brushless or linear motor
- Motor voltage rating 12-60 VDC (IONI supply voltage is 5 - 52 VDC)
- Motor current rating 0.1 - 23A (choose drive model accordingly, IONI Pro HC, maximum output is 23A, IONI Pro 18A, and IONI 15A)
- Servo motor must be equipped with an incremental encoder (position sensor) with resolution of 100 to 1000000 pulses per revolution.
Stepping motor requirements
- Two-phase stepping motor with 0.5 - 15A current rating, no feedback device needed. Can be used in position and velocity control mode. Torque mode not possible. Stepper voltage rating is irrelevant, but generally lower voltage & higher current stepper is better.
Unsuitable/non-optimum motors
- Any non-permanent magnet motors: induction AC motor or DC motor with field coil - will not work
- Cheapest grade DC motor, such as one extracted from power drill - might not give satisfying performance
- Motor with very high voltage, such as 200 VAC AC servo motor - it will work if it has incremental encoder feedback, but maximum rotation speed is limited due to drive voltage. Consider Argon servo drive for motors above 100 volts rating.
