*1. An External Regeneration Resistor can be connected. Connect this resistor if the regenerative energy exceeds regeneration absorption capacity in the Servo Drive.
Note: 1.The dynamic brake operates when the main circuit power supply or the control circuit power supply is turned OFF.
Note: 2.When turning OFF the main circuit power supply, turn OFF the RUN Command Input (RUN) signal at the same time.
