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 Power Module.
Note
Additional inputs must be controlled for the following cabinet units (synchronizers):
• An additional digital input on the CU320-2 and
• The terminals (-X41:1, -X42:2) on the Control Interface Module of the second Power
Module connected in parallel.
Synchronizers:
• for 380 to 480 V 3 AC:
6SL3710-2GE41-1AA3, 6SL3710-2GE41-4AA3, 6SL3710-2GE41-6AA3
• for 500 to 600 V 3 AC:
6SL3710-2GF38-6AA3, 6SL3710-2GF41-1AA3, 6SL3710-2GF41-4AA3
• for 660 to 690 V 3 AC:
6SL3710-2GH41-1AA3, 6SL3710-2GH41-4AA3, 6SL3710-2GH41-5AA3
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 Control Interface Module
of the Power Module must be performed in 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
