DYNAMIXEL

DX-116

Example 16

Set the Dynamixel with ID=0 to have a Compliance Margin = 1 and Compliance

Slope=0x40

The following graph shows the Angle Error and Torque Output.

If the position is slightly deviated from the goal position, the motor will generate

a high torque to try to adjust its position to that of the goal position. The true

control method is different due to the inertia. The condition provided in the

above example can be shown in the graph below:-

A : CCW Compliance Slope(Address0x1D) = 0x40(Approximately 18.8°)

B : CCW Compliance Margin(Address0x1B) = 0x01 (Approximately 0.29°)

C : CW Compliance Margin(Address0x01A) = 0x01(Approximately 0.29°)

D : CW Compliance Slope(Address0x1C) = 0x40 (Approximately 18.8°)
