*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.
2.
When turning OFF the main circuit power supply, turn OFF the RUN Command Input (RUN) signal at the same time.
