    Why does my HPtec SD4030B3 motor get so hot when it's running?
    • Q

      If your HPtec Control Unit motor's temperature rises abnormally high during rotation, it's likely because the RUN potentiometer setting is too high for the motor's rated current. To resolve this, reduce the RUN potentiometer setting.

      If the motor of your HPtec Control Unit isn't turning, it could be due to the command pulse not being input. Check the host controller side to ensure the command pulse is correctly sent.
