Parameters
Settings for DC braking
Parameter Description Setting
p0347[0...n] Motor de-excitation time [s] 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
p1230[0...n] BI: DC braking activation Sets the signal source to activate DC braking.
1 signal: DC braking activated.
0 signal: DC braking deactivated.
Factory setting: 0
p1231[0...n] Conguring DC braking 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
p1232[0...n] DC braking, braking current [A] Sets the braking current for DC braking.
Factory setting: 0
p1233[0...n] DC braking duration [s] Sets the DC braking time (as fault response).
Factory setting: 1
p1234[0...n] Speed at the start of DC braking
[rpm]
Sets the starting speed for DC braking.
Factory setting: 210000
