Argon Servo Drive

Versatile servo drive ARGON supports virtually any type of industrial servo motor including AC, Brushless DC, Brush DC and Linear motors. 

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

Motor's best friend

Servo drive and AC servo motors
  • High dynamic range torque control

Maximized versatility - thanks to HDRT, a single model drives AC, BLDC, Linear and DC servo motors from 50 W to 1500 W

  • Open source architecture

Argon has an dedicated ARM CPU for user's custom functionality

  • 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

  • Ruggedness taken to the max

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

  • Safety built in

3-way redundant safe torque off with motor braking

The value of simplicity

ARGON reduces the number of motion control components to the bare minimum. A typical PC controlled multiaxis 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 IONI drive allowing mixing different kinds of drives.

In addition to SimpleMotion bus, ARGON 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

Everything included

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