Setting Explanation
Setting Explanation
0 Stop Servomotor using dynamic brake (dynamic brake stays ON after Servomotor has stopped).
1 Stop Servomotor using dynamic brake (dynamic brake released after Servomotor has stopped).
2 Stop Servomotor using free run.
• Select the stopping process for when the servo is turned OFF or an alarm occurs.
• Dynamic Brake Operation when Power Is Turned OFF
The dynamic brake will remain ON if the main circuit and control circuit power supplies are turned OFF
for Servo Drivers of the capacities listed below. This means that it will be slightly more difficult to turn
the motor shaft by hand than it is when the dynamic brake is OFF. To release the dynamic brake, dis-
connect the Servo Motor wiring (U, V, or W). Always confirm that any disconnected wires are con-
nected properly before turning ON the power supplies again.
