34 DC motor driver module XN-322-1DCD-B35
The XN-322-1DCD-B35 features a DC motor driver that can be used to run a
brushed motor, as well as two current outputs that can be used to drive two
external LEDs. These current outputs have rated operational currents of
20 mA and 350 mA.
The power control module can be used to run a DC motor with supply
voltages of 12 – 30 V and a maximum motor current of 3.5 A. It can also
accommodate higher inrush currents briefly. The output power is controlled
with a PWM output, and the operating direction can be defined with the
polarity of the switched output driver stage. Accordingly, the output power
must be controlled using duty cycles.
In addition, these DC motor driver modules provide up-to-date operating data
on the motor so that the information can be used for further analysis or
display if necessary.
• Motor driver temperature
• Current motor current
• Motor status
• Let-through energy
• Diagnostics information
In order to integrate the motor into a speed control system, it is
recommended to provide a speed feedback signal by using a rotary encoder
on the motor together with an XN-322-1CNT-8DIO or XN-322-20DI-PCNT
module. This will make it possible to determine the motor's speed, operating
direction, and covered distance (angle of rotation).
The LED drivers can be programmed in such a way that the corresponding
LEDs will signal the information obtained by the module. For example, a
motor's speed or load can be represented by different LED brightness levels.
