1. Status after stopping is as defined in Pr5.10.
2. Servo stopping method is as defined in Pr5.10. Deceleration time t is determined by whichever
comes first between time set in Pr6.14 and time needed for motor to drop below velocity set in Pr4.39.
After deceleration time t, dynamic braking will be off and holding brake signal will be set to OFF (Holding
brake is activated. Although BRK-OFF signal is valid, actual activation of holding brake is dependent on
whether the motor comes with holding brake).
3. BRK-ON signal doesn't indicate the activation of holding brake but the invalidation of the signal.
Holding brake is not applied when BRK-ON signal is valid. Same idea goes for BRK-OFF signal.
