Selecon of the braking method.
•
The braking method(s) selected is/are acvated if the DC-bus voltage
exceeds the voltage threshold for the braking operaon shown in
0x2541:002 (P706.02).

Read only: x V
Display of the acve voltage threshold for the braking operaon.
•
The v
oltage 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 staonary DC voltage
in the DC bus.

me
(Brake management: Del.overr.me)

Maximum permissible me for the deceleraon override by means of
the braking method selected in 0x2541:001 (P706.01).
•
If the DC-bus voltage does not fall below the voltage threshold for
braking operaon shown in 0x2541:002 (P706.02) within this me,
the motor is decelerated further.
•
The me is only reset if the voltage threshold shown in 0x2541:002
(P706.02) is not reached.
12.1.1 Stopping the deceleraon ramp funcon generator
The deceleraon ramp funcon generator is stopped for a short me if the voltage threshold
f
or braking operaon is exceeded.
Details
When this braking method is selected, the maximum permissible me for the deceleraon
override has to be set in 0x2541:005 (P706.05).
•
If the DC-bus v
oltage does not fall below the voltage threshold for braking operaon
shown in 0x2541:002
(P706.02) within this me, the motor is decelerated further.
•
The me is only reset if the voltage threshold shown in 0x2541:002 (P706.02) is not
reached.
