3.9  Selecting and Connecting a Dynamic Brake Unit
3-43
3.9.4 Setting the Dynamic Brake Answer Function
With the dynamic brake answer function, you can use auxiliary contacts of the contactor that is used in the 
dynamic brake circuit and the dynamic brake answer signal (/DBANS) to detect welding or failure to opera-
tion.
To use the dynamic brake answer function, select a contactor that has auxiliary contacts.
Note: The dynamic brake answer function cannot be used with a Yaskawa dynamic brake unit because there are no auxil-
iary contacts on the contactor.
The dynamic brake answer signal is assigned with Pn515.2.
Example
If you use a dynamic brake contactor with NO contacts, input the dynamic brake answer signal (a signal from 
NO auxiliary contacts) to CN1-45 and set Pn515 to n.E.
Connect the dynamic brake answer signal (/DBANS) to the SERVOPACK’s I/O connec-
tor (CN1).
