Description

Advanced commissioning
6.18 Electrically braking the motor
Setting
Sets the de-magnetizing time (for asynchronous
motors) after the converter pulses have been
canceled (calculated after quick commissioning).
The converter can trip due to an overcurrent dur-
ing 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
Setting
Enter the fault number for which DC braking
should be activated, e.g. p2100[3] = 7860 (exter-
nal fault 1).
Factory setting: 0
Assign the fault response: p2101[3] = 6 (internal
armature short-circuit / DC braking).
The fault is assigned as an index of p2100. Assign
the same index of p2100 or p2101 to the fault
and fault response.
The converter's List Manual lists in the "Faults and
alarms" list the possible fault responses for every
fault. Entry "DCBRK" means that you may set DC
braking as response for this fault.
Factory setting: 0
