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. Entry "DCBRK" means that you may set DC braking as response for this fault.
DC braking voltages
The line supply voltage available to the Inverter determines the amount of rectified brake
voltage available for DC braking function. Listed in the following table are examples of the
correlation between the input AC voltage to the available DC voltage for the DC braking
function.
Line voltage 380 V AC
Rectified brake 171 V DC
voltage
The following formula can be use a guide to the rectified brake voltage that is available from
the line voltage:
Line voltage x 0.45 = Brake coil voltage
For example: 400 V AC x 0.45 = 180 V DC.

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

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.
