5.2 SERVOPACK Models with a Built-In Dynamic Brake5.2.4 Setting the Energy Consumption and Resistance of the Dynamic Brake Resistor5-95 Wiring and Settings for the Dynamic Brake7. Set Pn601 (Dynamic Brake Resistor Allowable Energy Consumption) and Pn604(Dynamic Brake Resistance).Refer to the following section for details on the settings.5.2.4 Setting the Energy Consumption and Resistance of the Dynamic Brake Resistor on page 5-95.2.4 Setting the Energy Consumption and Resistance of theDynamic Brake ResistorIf an External Dynamic Brake Resistor is connected, you must set Pn601 (Dynamic BrakeResistor Allowable Energy Consumption) and Pn604 (Dynamic Brake Resistance).*1. SGD7S-210D to 370D SERVOPACKs require three Dynamic Brake Resistors. For this parameter setting, enterthe total value of resistor capacity of the three resistors.*2. SGD7S-210D to 370D SERVOPACKs require three Dynamic Brake Resistors. For this parameter setting, enterthe resistance of one Dynamic Brake Resistor multiplied by .Set Pn601 to the capacity of the Dynamic Brake Resistor that you calculated when selecting theconnected External Dynamic Brake Resistor or the capacity of the Resistor as reported by themanufacturer.Refer to the following section for details on the energy consumption of the Dynamic BrakeResistor. Energy Consumption of the Dynamic Brake Resistor on page 5-6WARNING If you connect an External Dynamic Brake Resistor, set Pn601 and Pn604 to suitable values.Failure to set these parameters will cause an A.730 alarm (Dynamic Brake Overload) to bedetected incorrectly and can destroy the External Dynamic Brake Resistor, cause unintendedoperation during an emergency stop, cause damage to the machine, and cause burning orinjury. When you select an External Dynamic Brake Resistor, make sure that it has a suitableenergy consumption and resistance.There is a risk of personal injury or fire.CAUTION Mount Dynamic Brake Resistors only on nonflammable materials. Do not mount them on ornear any flammable material.There is a risk of fire.Pn601*1(2601h)Dynamic Brake Resistor Allowable Energy ConsumptionSetting Range Setting Unit Default Setting When Enabled Classification0 to 65,535 10 J 0 After restart SetupPn604*2(2604h)Dynamic Brake ResistanceSetting Range Setting Unit Default Setting When Enabled Classification0 to 65,535 10 mΩ 0 After restart SetupSpeed Position TorqueSpeed Position Torque3
