Parameter
p2100
p2101 = 6
The fault is assigned an index of p2100. Assign the same index of p2100 or p2101 to the fault and
fault response.
The inverter's List Manual lists in the "Faults and alarms" list the possible fault responses for every
fault. The "DCBRAKE" entry means that it is permissible to set DC braking as response for this par-
ticular fault.

Compound braking
Typical applications for compound braking include:
● Centrifuges
● Saws
● Grinding machines
● Horizontal conveyors
For these applications, the motor is normally operated with a constant speed, and is only
braked down to standstill after longer periods of time.

Configuring DC braking as a response to faults
Description
Set fault number for fault response (factory setting 0)
Enter the fault number for which DC braking should be activated, e.g. p2100[3] = 7860
(external fault 1).
Fault response setting (factory setting 0)
Assigning the fault response: p2101[3] = 6.
