3 Wiring and Connection3.9.3 Setting the Dynamic Brake Unit3-423.9.3 Setting the Dynamic Brake UnitUse the parameters shown in the tables here to make the settings for the following: the servomotor stoppingmethod when the servo is turned OFF, the output signals used to control the dynamic brake contactor, and thecapacity of the dynamic brake resistor in relation to whether or not a dynamic brake has been connected.The servomotor stopping method when the servo is turned OFF is set with parameter Pn001.0.When using a dynamic brake resistor from a company other than Yaskawa, set Pn00D.1 (second digit) to 0 or1 in accordance with the following table depending if an NO or NC contact is used.The dynamic brake resistor capacity is set with Pn601.(1) Using a Yaskawa Dynamic Brake Unit• Set Pn001 to n.0.• Not necessary to set Pn00D• Set Pn601 to 0.(2) Using a Dynamic Brake Resistors from Another Company• Set Pn001 to n.0.• Set Pn00D to either n.0D or n.1 depending on your system.• Set Pn601 to 20% of the resistor capacity of your dynamic brake.(3) Not Using a Dynamic Brake• Set Pn001 to n.2.• Not necessary to set Pn00D• Set Pn601 to 0.Parameter Meaning WhenEnabled ClassificationPn001n.0[Factorysetting]Stops servomotor by applying DB (dynamic brake).After restart Setupn.1 Stops servomotor by applying DB and then releases DB.n.2 Stops servomotor without applying DB by coasting to astop.Parameter Meaning WhenEnabled ClassificationPn00Dn.0[Factorysetting]Enables the control of an NO contactor(The dynamic brake is activated when current is sup-plied to the contactor coil.)

The Pn601 param-eter is for the multi-winding drive unit. Do not mistakenly change the SERVOPACKparameter.
