IONI Servo & Stepper Drive

IONI drives virtually any type of industrial servo motor including AC, Brushless DC, Brush DC, Linear servo motors and stepping motors from 5 Watt to 700 Watts.

Whether the application requires position, velocity or torque operating mode, IONI handles them all out-of-the-box. Built-in motion profiler enables simple point-to-point moves as well as continuous synchronous motion tracking.

Build low cost multiaxis systems

Chain IONICUBE motherboards to form 1 to 32 axis systems. Install them centralized or distributed to near motors.

Advantage of high dynamic range torque control

One drive to rule them all - thanks to High Dynamic Range Torque control, IONI seamlessly drives motors from 5 W to 500 W with ultimate smoothness

Eliminate axis limit switches

Internal axis homing function with sensorless hard-stop detection mode and soft travel limits eliminates the need of physical end-of-travel switches and their wiring

Relax, you can rely on it

Device protections include over current, short circuit, over voltage, under voltage, over temperature and I²t protections and communication error detection

The value of simplicity

IONI reduces the number of motion control components to the bare minimum. A typical PC controlled multi-axis system can be implemented by using direct USB or RS485 driven SimpleMotion field bus to the servo drives. The same bus carries a dedicated safety stopping circuit without additional wiring. The wiring scheme is compatible with ARGON drive allowing mixing different kinds of drives.

In addition to SimpleMotion bus, IONI also reads traditional control signals, such as pulse & direction, PWM, and analog velocity reference out of the box. In such case, SimpleMotion is only used for drive configuration with Granity.

Motion control system with USB interface

Part of your system

Commands to IONI servo 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 bus protocol, open source library available)

Real-time requirements? Not one of your problems.

Implement your multi-axis motion control application with SimpleMotion buffered motion stream API and break free from the need of real-time motion controller.

User application just fills-up drive buffers with position setpoints and drives will run the commands synchronously based on their internal precision clocks. This allows host motion controller to be just an ordinary non-realtime PC application.

Best of all? Everything can be done over omnipresent USB or RS485 port.

If hard real-time control is required, SimpleMotion bus also supports instantenous commands up to 20 kHz command rate.

Small outside, big inside

IONI servo drive was made possible by building on the latest and greatest components available today. This do not only save space, but also drastically reduce number of parts to be paid and fail.

IONI is solely made out of the highest grade components from the most reputable hi-tech companies such as Texas Instruments, ST Microelectronics and Infineon.

Everything included

Hardware of IONI has been designed from ground up without any historical payload. This not only costs less but also yields unforeseen flexibility and reliability.

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.
