Control of a mechanical brake
The mechanical brake (a disk or drum brake) is used for holding the motor and
driven machinery at zero speed when the drive is stopped, or not powered.
Example
The figure below shows a brake control application example.
WARNING!
Make sure that the machinery into which the drive with brake control
function is integrated fulfils the personnel safety regulations. Note that the frequency
converter (a Complete Drive Module or a Basic Drive Module, as defined in IEC
61800-2), is not considered as a safety device mentioned in the European
Machinery Directive and related harmonised standards. Thus, the personnel safety
of the complete machinery must not be based on a specific frequency converter
feature (such as the brake control function), but it has to be implemented as defined
in the application-specific regulations.

Brake control logic is integrated in
the drive application program. The
brake control hardware and wirings
needs to be done by the user.
- Brake on/off control through relay
output RO1.
- Brake supervision through digital
input DI3 (optional).
- Emergency brake switch in the
brake control circuit.
