  • Customization to Suppress EMI in DC Motors
    re-inverts one input and adds the voltage in the lines, effectively. canceling electromagnetic interference (EMI). Therefore, if a +1V noise spike enters the 5V system, the lines. would carry 6V and 1V for the duration of the spike, then the receiver would invert the 1V input and detect

  • Application Note: Common Causes for Stepper Drive Failures
    the motor at a maximum of 20,000 pulses per second. Pulse rates of above 60,000 pulses per second can damage the drive. Avoid putting Pulse rates into the driver above 60,000 pulses per second. PROBLEM Stalling the motor. SOLUTION In some cases, stalling the motor causes a large voltage spike
