Controlling the safety functions
7.3 Control of "STO" and "SS1" via terminals on the Control Unit and the Motor/Power Module
Safety Integrated
164 Function Manual, 05/2010, A5E03264275A
Functional principle
The first shutdown path for the integrated safety functions is activated via a digital input on
the control unit; digital inputs DI0 to DI7 are available for this purpose.
Chassis Motor Module
● The second shutdown path for the integrated safety functions is activated via the
terminals (-X41:1, -X42:2) on the Control Interface Module of the Power Module.
Booksize Cabinet Kit
● The second shutdown path for the integrated safety functions is activated via the
terminals (-X21:3, -X21:4) on the booksize Motor Module.
In the case of a booksize Double Motor Module, terminals -X22:3 and -X22:4 are at the
disposal of the second motor connection for the activation of the second shutdown path.
The selection and deselection must be executed concurrently. The time delay that is
unavoidable due to mechanical switch processes, for instance, can be adapted via
parameters.
The selection of the safety function on the control unit and on the motor module must be
executed over two channels. A switch in accordance with ISO 13850/ EN 418, positive
opening in accordance with EC 60947-5-1, or a certified safety controller must be used as
activation element.
DANGER
Responsibility for selecting the correct activation element for the purpose of compliance of
the overall system with the required standard (DIN EN ISO 13849-1 (formerly EN954-1)
Cat. 3 PL d or DIN EN 61508 SIL2) rests with the user.
