11.12 Brake control
This basic function is used for a wear-free control and monitoring of a motor holding brake which
in the simplest case is connected to the optionally available motor brake control module
(accessories).
Alternatively, the motor holding brake can be controlled via a digital output and monitored via a
digital input.
Intended use
Motor holding brakes are used to hold axes in the case of controller inhibit or pulse inhibit and in
the "Mains OFF" system state. This is not only important for vertical axes, but for instance also for
horizontal axes for which an uncontrolled movement can bring about diverse problems.
Examples:
• Loss of the reference information after mains OFF and further spinning of the drive.
• Collision with other moving machine parts.

Danger!
Please bear in mind that the motor holding brake is an important element of the safety
concept of the entire machine. Thus maintain this system component with special care!

Stop!
Motor holding brakes at Lenze motors are not designed for braking during operation.
The increased wear resulting from braking during operation may lead to an early
destruction of the motor holding brake!

Please observe the notes in the hardware manual for mounting and electrical
installation of the motor holding brake!
