Conguring DC braking as a response to faults
Parameter Description Setting
p2100[0…
19]
Changing the fault reaction, fault
number
Enter the fault number for which DC braking should
be activated, e.g. p2100[3] = 7860 (external fault
1).
Factory setting: 0
p2101[0…
19]
Changing the fault reaction, reac‐
tion
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
7.21.2 Dynamic braking
Typical applications for dynamic braking require continuous braking and acceleration
operations or frequent changes of the motor direction of rotation:
• Horizontal conveyors
• Vertical and inclined conveyors
• Hoisting gear
