Figure 11-30 RFC-A mode (brake controller (12.052) = 0) and RFC-S mode
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.
WARNING
The control terminal relay can be selected as an output to release a brake. If a drive is set up in this manner and a drive replacement takes
place, prior to programming the drive on initial power up, the brake may be released.
When drive terminals are programmed to non default settings the result of incorrect or delayed programming must be considered. The use of
a NV media card in boot mode or an SI-Applications module can ensure drive parameters are immediately programmed to avoid this situation.
