DC-injection braking as response to a fault can erroneously be replaced by quick stop (corrected from V1.6.3)

Corrected from: 
- i700 servo inverter V01.06.03.9953
 
Response of the new version:
DC-injection braking as response to a fault for braking the motor can no longer be erroneously replaced by the quick stop function. Once activated, the function is now "locked" until the "Fault" state is reached in which operation is inhibited. 
 

What happens?
DC-injection braking as response to a fault for braking the motor can erroneously be replaced by the quick stop function. In this case, the motor will not be optimally braked.
 
When does the problem occur? 
The problem occurs, if the cause of the fault disappears while the controller is already in the "Fault reaction active" state and DC-injection braking is being executed. In the case of a feedback error, a loose contact in the feedback cable or a fault reset might lead to this. 
 
Which products are affected?
- i700 servo inverter ≤ V01.05.06.9665

Short-term measures/recommendations:
If necessary, set 'Response to error' 0x605E = 0 (pulse inhibit) and do without controlled braking in the event of a fault.

Evaluation:
The probability that this rather theoretical scenario will actually occur in practical operation is very low.
