Setting the function

The internal voltage protection is set with p1231 = 3.

Activating the function

The function is activated and initiated if the signal source of p1230 is set to a "1" signal.

Deactivating the function

The function is deactivated if the signal source of p1230 is set to a "0" signal. When triggered

by a fault, the fault must have been removed and acknowledged.

Configuring a fault reaction

Changing the fault response

The responses can be set to selected faults using parameters p2100 and p2101. Only

responses can be set that are intended for the corresponding faults.

Using parameter p0491, responses to encoder errors of a motor encoder can be set (F07412

and many F3yxxx, y = 1, 2, 3).

Motor type change

If the preconditions for armature short-circuit braking or DC braking are no longer satisfied after

a motor type has been changed (see p0300), then those modified parameters that have

armature short-circuit braking or DC braking as a response (e.g. p2100, p2101 or p0491) are

set to the factory setting.

Deselecting armature short-circuit or DC braking

Armature short-circuit or DC braking cannot be deactivated using parameter p1231, as long as

a response parameterized with p2100, p2101 or p0491 has a fault condition.
