6.8 Macro 7 - Brake control
It is recommended that the brake control in menu 12 is used instead of Macro 7 - Brake control.
Table 6-14 Macro 7 menu 0 programmable parameters
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
Where a safety hazard may exist the drive alone must not be permitted to release the brake. An independent safety interlock must be
provided to ensure safe operation in the event of drive failure or incorrect operation.
WARNING
Macro 7 Brake control
The brake control macro configures the drive to apply or release a mechanical brake on a motor in a crane or hoist application. The drive issues a
brake release signal via a digital output when the relevant conditions are met.
