Stepper motor power stage with a powerful processor

Die Schrittmotorendstufe iPM 206 verfügt über einen leisungsfähigen 32-Bit-Prozessor
Die Schrittmotorendstufe iPM 206 verstärkt die Signale einer Schrittmotorsteuerung mit Puls- und Richtungssignal an 2-Phasen-Schrittmotoren.

The stepper motor power stage iPM 206 serves as amplifier between the controller and the 24-V stepper motor. It is compatible with all controllers with pulse and direction signal and it is suited for 2-phase stepper motors with a rated current of up to 6 A. The motor phase current is adjustable between 0 A and 6 A by means of a 16-level coded rotary switch.

The iPM 206 is equipped with a powerful 32-bit processor. This offers a large dynamical range for the control of both current and rotational speed. Utilising the DDS procedure (Direct Digital Synthesis) combined with a PLL (Phase Locked Loop) allows microsteps to be created depending on the selected number of steps. This ensures significantly quieter motor operation at a lower stepping frequency range. The maximum number of steps is 16,000 steps/revolution; the theoretical positioning precision thus is 0.0225 degree.

Product features

  • Controlling 2-phase bipolar stepper motors
  • High resolution due to microstepping, even at low frequencies there is no “motor growling”
  • 200 to 16,000 steps/revolution, adjustable in 8 levels
  • Digital input to switch between two pre-selected numbers of steps  
  • Pulse and directional inputs for motor operation
  • Enable-input to activate electronics
  • Gate input for pulse signal
  • Ready signal at relay contact
  • Motor phase current adjustable in 16 levels
  • Current is reduced by 50 % when the motor is not running
  • Monitoring and display of: Overvoltage and undervoltage, maximum current and operating temperature
