Figure 5-20 Open-loop brake function
Figure 5-21 Open-loop brake sequence
The brake control functions are provided to allow well co-ordinated operation of an external brake with the drive. While both hardware and
software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or
failure would result in a risk of injury. In any application where the incorrect operation of the brake release mechanism could result in injury,
independent protection devices of proven integrity must also be incorporated.
