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 nec-
essary to connect a dynamic brake unit.
3.6.1 Selection
Use the following tables to select a dynamic brake unit or dynamic brake resistor.
3.6.2 Connections
(1) Using a Dynamic Brake Unit from Yaskawa
When connecting a dynamic brake, refer to the following diagram.
Note: The dynamic brake answer function cannot be used, because the contactor has no auxil-
iary contacts.
