The braking method(s) selected is/are activated if the DC-bus voltage
exceeds the voltage threshold for the braking operation shown in
0x2541:002 (P706.02).

Display of the active voltage threshold for the braking operation.
The voltage threshold shown depends on the mains voltage selected
in
0x2540:001 (P208.01) and the voltage value set in 0x2541:003
(P706.03).
The voltage threshold must be higher than the stationary DC voltage
in
the DC bus.

10.5.1. Stopping the deceleration ramp function generator
The deceleration ramp function generator is stopped for a short time if the voltage
threshold for braking operation is exceeded.
Details
When this braking method is selected, the maximum permissible time for the deceleration
override has to be set in 0x2541:005 (P706.05).
• If the DC-bus voltage does not fall below the voltage threshold for braking operation
shown in 0x2541:002 (P706.02) within this time, the motor is decelerated further.
• The time is only reset if the voltage threshold shown in 0x2541:002 (P706.02) is not
reached.
