If the regenerative energy generated in deceleration or descent in an application is too large, the main circuit voltage [r/min]...
  • Page 613 Appendices Braking Resistor Selection Detailed Braking Resistor Selection When the usage rate of the braking resistor selected on Select a braking resistor from the required braking resistance the previous page exceeds 10% ED, or when an and the average regenerative energy described on the left extremely large braking torque is required, use the section.
