Status Packet Result NO ERROR
You can verify the Torque Enabled status by trying to move the output of the actuator by
hand.
Example 17 Setting the Compliance Margin to 1 and Compliance Slope to 0x40 for a
Dynamixel actuator with an ID of 0
Compliance The Angle Error and Torque Output can be represented with the following graph.

X:Angle Error
CW
Goal Position CW
CCW
Even if the position deviates a little from the goal position in the CW direction, a large
amount of torque is generated in the CCW direction to compensate for this. However,
since inertia must be considered, a realistic implementation differs from this approach.
Considering this, the given conditions can be represented by the following graph.

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