Parameterizing a DC & compound brake
Parameter Description
P1230 Enables the DC brake
Enables DC braking via a signal that was used by an external source (BICO). The
function remains active as long as the external signal is active.
P1232= DC brake current (entered in %)
Defines the strength of the direct current in [%] with respect to the rated motor current
(P0305)
P1233= Duration of the DC braking (entered in s)

Parameter P1236 defines the direct current superimposed on the motor current after the
DC link voltage threshold has been exceeded.
P1236 = 0 Compound brake disabled
P1236 = 1 - 250 Current level of braking direct current as a % of the rated motor current
(P0305)
