5.3 Control of "STO" and "SS1" via terminals on the Control Unit and the Motor/Power Module
Principle of operation
The first switch-off signal path for the integrated safety functions is controlled via a digital
input on the Control Unit. Digital inputs DI 0 to DI 7, DI 16, DI 17, DI 20 and DI 21 are
available for this purpose.
The second switch-off signal path for the integrated safety functions is controlled via the
terminals (-X41:1, -X42:2) on the Control Interface Module of the Motor Module or the Motor
Module, format Chassis-2.
Selection and deselection must be simultaneous. The time delay that is unavoidable due to
mechanical switching operations, for example, can be adapted via parameters. p9650
specifies the tolerance time within which selection/deselection of the two monitoring
channels must take place to be considered as "simultaneous".
The selection of the safety function on the Control Unit and on the Motor Module must be
executed over two channels. A switch according to ISO 13850, positive opening according to
IEC 60947-5-1 or a certified safety control must be used as actuating element.
Failure of the safety functions as a result of an unsuitable actuating element
An unsuitable actuating element may cause the safety function to fail which can result in
death or serious injury.
• Select the correct actuating element to comply with the standard to be complied with
