Introduction to AM-DC2-2D
- Forward and reverse drive as well as speed control is possible
- Driving Signal: Can be controlled easily using Enable, Dir and PWM.
- NEWTC's motor driver series are compatible with each other so if you need large number of motor controller, you can reuse programs wwithout modification to the parent model.ithout modification or with small changes only.

* Connecting the Hardware
- Control input signal.
Connect the Motor control signal like / Enable, / Break, Dir, PWM signal etc to the output port of the MCU. To use as fixed signal, it can be connected 0V or 5V.

Operation |
|
/Enable
(AM-DC2-2D only, using L298) |
Motor corresponding to a channel can be started or stopped
0 : Enable
1 : Disable |
|
/Break
(AM-DC1-3D only, using LMD18200) |
Apply torque and stop a motor corresponding to a channel
0 : Break On
1 : Break Off |
|
Dir |
Can determine the direction of rotation of the motor.
0 : Rotate in reverse direction
1 : Rotate in forward direction
(Can be different depending on motor connection) |
|
PWM |
. Adjust motor speed.
0 : Stop Motor
1 : Rotate Motor
Motor speed can be controlled depending on ration of 1 and 0 |
To check the operation of motor and motor drive, connect /Enable -> 0V, Dir -> 0V, PWM -> 5V and the motor will rotate in the reverse direction.
