Description

maxon control’s EPOS2 24/2 is a small-sized, full digital, smart motion controller. Due to its flexible and high efficient power stage, the EPOS2 24/2 drives brushed DC motors with digital encoder as well as brushless EC motors with digital Hall sensors and encoder.

The sinusoidal current commutation by space vector control offers the possibility to drive brushless EC motors with minimal torque ripple and low noise. The integrated position, velocity and current control functionality allows sophisticated positioning applications. The EPOS2 24/2 is especially designed being commanded and controlled as a slave node in a CANopen network. In addition, the unit can be operated via any USB or RS232 interface.
