Wiring example
The figure below shows a brake control wiring example. The brake control hardware
and wiring is to be sourced and installed by the customer.
WARNING! Make sure that the machinery into which the drive with brake
control function is integrated fulfills 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.
The brake is controlled by bit 0 of parameter 44.01 Brake control status. The source
of brake acknowledge (status supervision) is selected by parameter 44.07 Brake
acknowledge selection. In this example,
• parameter 10.24 RO1 source is set to Open brake command (ie. bit 0 of 44.01
Brake control status), and
• parameter 44.07 Brake acknowledge selection is set to DI5.
