3.9 Selecting and Connecting a Dynamic Brake Unit3-433 Wiring and Connection3.9.4 Setting the Dynamic Brake Answer FunctionWith the dynamic brake answer function, you can use auxiliary contacts of the contactor that is used in thedynamic 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.ExampleIf you use a dynamic brake contactor with NO contacts, input the dynamic brake answer signal (a signal fromNO 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).Parameter Meaning WhenEnabled ClassificationPn515n.0Detects dynamic brake (DB) contactor errors when theinput signal of CN1-40 is ON (closed) while the DB isapplied.After restart Setupn.1 Detects DB contactor errors when the input signal ofCN1-41 is ON (closed) while the DB is applied.n.2 Detects DB contactor errors when the input signal ofCN1-42 is ON (closed) while the DB is applied.n.3 Detects DB contactor errors when the input signal ofCN1-43 is ON (closed) while the DB is applied.n.4 Detects DB contactor errors when the input signal ofCN1-44 is ON (closed) while the DB is applied.n.5 Detects DB contactor errors when the input signal ofCN1-45 is ON (closed) while the DB is applied.n.6 Detects DB contactor errors when the input signal ofCN1-46 is ON (closed) while the DB is applied.n.7Disables DB contactor error detection of DB answersignal.n.8[Factorysetting]n.9 Detects DB contactor errors when the input signal ofCN1-40 is OFF (open) while the DB is applied.n.A Detects DB contactor errors when the input signal ofCN1-41 is OFF (open) while the DB is applied.n.B Detects DB contactor errors when the input signal ofCN1-42 is OFF (open) while the DB is applied.n.C Detects DB contactor errors when the input signal ofCN1-43 is OFF (open) while the DB is applied.n.D Detects DB contactor errors when the input signal ofCN1-44 is OFF (open) while the DB is applied.n.E Detects DB contactor errors when the input signal ofCN1-45 is OFF (open) while the DB is applied.n.F Detects DB contactor errors when the input signal ofCN1-46 is OFF (open) while the DB is applied.
