Active threshold
i510
i550
R
-- ... [Actual value] ... -- V
DC link voltage threshold at which the braking is activated.
The threshold depends on the selected "Rated mains voltage" and pa-
rameter "Reduced threshold" (P706:3)
P706:3
0x2541:3
Reduced threshold
i510
i550
R/W
0 ... [0] ... 100 V
The activation of the braking method is reduced by this parameter.
P706:4
0x2541:4
Additional frequency
i510
i550
R/W
0.0 ... [0.0] ... 10.0 Hz
Additional Frequency for deceleration compound braking mode.
P706:5
0x2541:5
Deceleration override time
i510
i550
R/W
0.0 ... [2.0] ... 60.0 s
Maximum time in deceleration override braking mode. If the DC-Voltage
doesn't fall below in the defined time the inverter goes to fault state.

Brake resistor response
i550
R/W
0: Off: Inverter disable / Error
1: On: Disable/Off: Error
2: Off: Disable / On: Error
3: On: Disable / Error
Defines the behavior of the braking chopper in case of state Inhibit and
Error. (Used for inverters connected over DC-Link)
