Dynamic brake can be operated in the following cases
1. The main power off
2. The servo off
3. Protection action
4. Connector X4 driving ban importation (POT, NOT) action
On the above 1~4 cases, valid or invalid of dynamic brake can be determined by the parameters.
However, when the control power off, dynamic brake of size A-F keep valid condition.

1. Do not start / stop the motor by the servo signal (SRV-ON) . Built-in dynamic brake circuit may be damaged.
2. Do not drive the motor with external torque. Motor generates electricity by external torque.
Dynamic brake circuit will be damaged and it is possible that short-circuit current cause smoke or combustion.
3. Allow approx. 10 minutes pause when the dynamic brake is activated during high-speed running.
Resistor is damaged and the dynamic brake might not work when using it under more critical operating
condition.
