Miniature 700-watt servo motor drive with integrated motion controller


Granite Devices, a Finnish servo drive manufacturer, has released a new industrial servo motor drive contributing high degree of time and cost saving features to the machine automation market.

A “Swiss-army knife of motion control”, Ioni starts a new era of servo drives by bringing snap-on installation, built-in SIL2 safety functions and unforeseen compactness in 700 W class in just 70 x 37 x 7 mm form factor.

Ioni implements industry standard, torque, velocity and position controls for AC, brushless DC, brushed DC, linear servo motors and stepping motors between 2 W and 700 W power. 


An improved high dynamic range torque control allows seamlessly to connect a record breaking range of motor variants to a single drive type.

The “real beauty” of Ioni, says the company, is the the ability to perform multi-axis synchronous motion control out of non-realtime host, such as Windows PC with USB or Ethernet connection.

This has been achieved by the means of hardware side trajectory buffering and distributed clock synchronization. Customer’s motion control software just fills drives’ trajectory buffers to perform silky smooth multi-axis motion.

Under the hood, Ioni packs an unforeseen level of connectivity. Ioni Pro drive model holds all-inclusive support for incremental and sin/cos encoders as a standard feature. Drive connects directly to the fully open C/C++/C# programmable SimpleMotion bus as well as traditional digital pulse train and analog controllers.

IoniCube and IoniCube 1X motherboards are offered alongside with Ioni drives for customers to build 1-4 axis solutions or larger motion control systems by chaining the motherboards.

IoniCube motherboard schematics are also offered in open source fashion for customers to build their own purpose-built motherboards.

“Ioni has proven such Swiss-army knife of motion control approach feasible by using today’s latest technologies,” says company’s product architect, Timo Piiroinen.

Ioni is available worldwide directly through Granite Devices web shop immediately from the stock.

The Ioni product line is now in production with three Ioni model variants:

  • Ioni Standard;
  • Ioni Pro; and
  • the high current variant Ioni Pro HC.

The list prices for Ioni models are €149 for IONI Standard, €179 for Ioni Pro and €199 for Ioni Pro HC for orders of 1 unit.

The Motherboard prices are €149 for IoniCube and €75 for IoniCube 1X.
