r1239[8...13] CO/BO: DC braking status word
312
Description
Motor de-excitation time [s]
BI: DC braking activation
Configuring DC braking
DC braking, braking current [A]
DC braking duration [s]
Speed at the start of DC braking
[rpm]
Setting
Sets the de-magnetizing time (for asynchronous
motors) after the converter pulses have been can‐
celed (calculated after quick commissioning).
The converter can trip due to an overcurrent during
DC braking if the de-excitation time is too short.
Factory setting: 0
Sets the signal source to activate DC braking.
1 signal: DC braking activated.
0 signal: DC braking deactivated.
Factory setting: 0
Sets to activate DC braking.
0: No DC braking (factory setting)
4: DC braking
5: DC braking for OFF1/OFF3
14: DC braking below starting speed
Sets the braking current for DC braking.
Factory setting: 0
Sets the DC braking time (as fault response).
Factory setting: 1
Sets the starting speed for DC braking.
Factory setting: 210000
Status word of the DC braking.
.08: DC braking active
.10: DC braking ready
.11: DC braking selected
.12: DC braking selection internally locked
.13: DC braking for OFF1/OFF3
