Wiring 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.
The figure below shows a brake control wiring example. The brake control hardware
and wiring is to be sourced and installed by the customer.
The brake is controlled by bit 0 of parameter 44.1. The source of brake acknowledge
(status supervision) is selected by parameter 44.7. In this example,
• parameter 10.24 is set to Open brake command (ie. bit 0 of 44.1), and
• parameter 44.7 is set to DI5.
