7.3.4 Extended brake control
7.3.4.1 Features
The "extended brake control function" has the following features:
● Forced brake release (p0855, p1215)
● Application of brake for a 1 signal "unconditionally close holding brake" (p0858)
● Binector inputs for releasing/applying the brake (p1218, p1219)
● Connector input for threshold value for releasing/applying the brake (p1220)
● OR/AND block, each with two inputs (p1279, r1229.10, r1229.11)
● Holding and operational brakes can be activated.
● Function for monitoring brake feedback signals (r1229.4, r1229.5)
● Configurable responses (A7931, A7932)
● Application of brake after "Enable speed controller" signal has been canceled (p0856)
7.3.4.2 Function diagrams and parameters
