CT Servo

This controller allows you to control the state (translation or angle) of any kind of motor. The controller outputs feedback data through OUT1 and OUT2.

While the CT Servo is compatible with all kinds of motors, for best results you should connect it to a servo-designed motor. These include Linear Servo and Servo Motor.

The CT Servo outputs two kinds of feedback data through OUT1 and OUT2.

For rotary motors (DC Motor, Servo Motor)

The input servo control (IN1) is the target angle of the rotary motor. The target angle is 360 * IN1, which means that an input value of 0.5 corresponds to 180 degrees, for example. The CT Servo will always calculate the shortest path to the target angle.

The current angle of the motor will be reported through OUT1. The reported angle follows the same scheme as the input angle. When the motor has reached its target angle, IN1 is equal to or almost equal to OUT1.

The amount of torque that the motor is applying to reach its target angle is reported through OUT2. This value is a percentage of the maximum possible torque that the motor is capable of applying. A value of 1 means that the motor is applying as much torque as possible. This value should be relatively low unless the motor is stuck.

For linear motors (Linear Motor, Linear Servo)

The input servo control (IN1) sets the target position of the linear motors pivot. A value of 0 is one end of the motor, and a value of 1 the other end.

The current position is reported through OUT1.

The amount of force being applied to move the pivot is reported through OUT2. A value of 1 means maximum force is being applied and may mean that the motor is stuck.
