0x2541:001
(P706.01)
Brake energy management: Operang mode
(Brake management: Operang mode)
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).
0 Brake resistor The integrated brake chopper (brake transistor) is used.
4Use of a brake resistor ^ 445
1 Ramp funcon generator stop (RFGS) The deceleraon ramp funcon generator is stopped.
4Stopping the deceleraon ramp funcon generator ^ 447
2 Brake resistor + RFGS The brake resistor is supplied with current and the deceleraon ramp
funcon generator is stopped.
3 Inverter motor brake (IMB) + RFGS Braking with the "Inverter motor brake" braking method in connecon
with "Deceleraon ramp funcon generator stop" is executed.
4Inverter motor brake ^ 448
4 Brake resistor + IMB + RFGS Braking is performed by combining all three braking procedures.

Brake energy management: Acve threshold
(Brake management: Acve threshold)
•
Read only: x V
Display of the acve voltage threshold for the braking operaon.
•
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 staonary DC voltage
in the DC bus.

(P706.03)
Brake energy management: Reduced threshold
(Brake management: Red. threshold)
0 ... [0] ... 100 V
The voltage threshold for the braking operaon is reduced by the volt-
age value set here.
0x2541:005
(P706.05)
Brake energy management: Deceleraon override
me
(Brake management: Del.overr.me)
0.0 ... [2.0] ... 60.0 s
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.
0x2540:001
(P208.01)
Mains sengs: Rated mains voltage
(Mains sengs: Mains voltage)
•
Seng can only be changed if the inverter is inhibi-
ted.
Selecon of the mains voltage for actuang the inverter.
