3.9 Selecting and Connecting a Dynamic Brake Unit
To use the dynamic brake (DB), externally connect a dynamic brake unit or dynamic brake resistor to the
SERVOPACK to process the dynamic braking energy.
Set Pn001 to n.2 if you do not use the dynamic brake. In this case, it is not necessary to connect a
dynamic brake unit.
3.9.1 Selection
Use the following tables to select a dynamic brake unit or dynamic brake resistor.
(1) Using a Yaskawa Dynamic Brake Unit
(2) Using a Dynamic Brake Resistor from Another Company
To order a dynamic brake unit, contact the manufacturer directly.
Use the following dynamic brake contactors and surge absorption units.
∗ Use either a head-on or side-on main circuit surge absorption unit.
3.9.2 Selecting the Cable for the Dynamic Brake Unit
Use one of the following cables to connect the dynamic brake unit or dynamic brake contactor to CN115 on
the SERVOPACK.
