34 DC motor driver module XN-322-1DCD-B35XN300 slice modules 02/24 MN050002EN Eaton.com 26434 DC motor driver module XN-322-1DCD-B35The XN-322-1DCD-B35 features a DC motor driver that can be used to run abrushed motor, as well as two current outputs that can be used to drive twoexternal LEDs. These current outputs have rated operational currents of20 mA and 350 mA.The power control module can be used to run a DC motor with supplyvoltages of 12 – 30 V and a maximum motor current of 3.5 A. It can alsoaccommodate higher inrush currents briefly. The output power is controlledwith a PWM output, and the operating direction can be defined with thepolarity of the switched output driver stage. Accordingly, the output powermust be controlled using duty cycles.In addition, these DC motor driver modules provide up-to-date operating dataon the motor so that the information can be used for further analysis ordisplay if necessary.• Motor driver temperature• Current motor current• Motor status• Let-through energy• Diagnostics informationIn order to integrate the motor into a speed control system, it isrecommended to provide a speed feedback signal by using a rotary encoderon the motor together with an XN-322-1CNT-8DIO or XN-322-20DI-PCNTmodule. This will make it possible to determine the motor's speed, operatingdirection, and covered distance (angle of rotation).The LED drivers can be programmed in such a way that the correspondingLEDs will signal the information obtained by the module. For example, amotor's speed or load can be represented by different LED brightness levels.
