• In the output torque graph, acceleration in the positive direction (rising) is shown as positive, and
• The regenerative energy values in each region can be derived from the following equations.
Note Due to the loss of winding resistance, the actual regenerative energy will be approximately

calculated, and this value must be lower than the Servo Drive’s regenerative energy absorption
capacity. (The capacity depends on the model. For details, refer to Servo Drive Regenerative
