n , M2 = short circuit, Mode 2 。 potentiometer voltage + DOWN state control Reversible , STOP allowed to run( The default value for this speed mode ) STOP low ( short circuit to GND on ) is enabled, the driver can control the motor voltage and DOWN signals 。 high motor brake stops , the voltage and DOWN signal is inactive.DOWN HIGH forward and low reverse 。ADJ :05V input voltage signal corresponding to 0100% RPM rotational speed, direction depends on the DOWN state.3, M1 = short , M2 = short circuit , mode 3 。 pure button ( switching signal) controlLead out four lines, as then three buttons . Or and 5V microcontroller interface driver , MCU sends a low pulse more than 100 milliseconds . Drive current is 5 mA current required to drop .Press the STOP / DIR: whatever status, speed, motor brake immediately stops 。Press UP: positive dir
