EM-180A-M1 is developed for controlled ON-OFF driving and direction change of a DC-motor with brushes. Driver has advanced current limit features. It limits the motor current in start-up and jam-situations and that way protects the motor and mechanics from over torque. Driver has also an error output to indicate error / over current situations.
EM-180A-M1 is developed from EM-180M1 and it has extra features as impulse control mode and soft or rattle start selection. Rattle mode means that when current limit exceeded in start the driver gives little higher current and rattling, which help releases stuck of actuator of motor. Driver has also serial port which can be used to update a firmware or activates optional features.
The acceleration ramp time for start-up is adjustable to be suited for each application. So the motor voltage is not raised instantaneously but slowly to give a smooth start-up. As the control is set off, the motor is braked with so called dynamic braking, means that the motor poles are connected together. The current protection is double acting. First there is a continuous and adjustable current limit which decreases the motor voltage if the current exceeds the adjusted value. Second there is settable trip feature that cuts the motor voltage if the current limit value is exceeded. After trip the motor starts only to the opposite direction.
Additionally the driver doubles the adjusted current value for 0.3 seconds in start-up to ensure sufficient power to overcome the start-up friction.
