Outline
∗1. Speed regulation by load regulation is defined as follows:
∗2. Set Pn001 to n. 2 if you do not use the dynamic brake.
∗3. Refer to 3.8 Selecting and Connecting a Dynamic Brake Unit for details on dynamic brake units.
∗4. Refer to 3.7 Selecting and Connecting a Regenerative Resistor Unit for details on regenerative resistor unit.
∗5. Implement risk assessment and confirm that the safety requirements of the machine have been met.
