5.3.3 Safe torque off

The axis modules support the "safe torque off" safety function (formerly "safe

standstill"), "protection against unexpected start−up", in accordance with the

requirements of EN ISO 13849−1, Performance Level Pld. For this purpose, the

axis modules are equipped with two independent safety paths. The

Performance Level Pld is obtained if the output signal is additionally checked

with regard to correctness at X6/SO.

5.3.3.1 Implementation

In the axis module, the "safe torque off" connection is implemented with

optocouplers. The optocouplers isolate the following areas electrically from

each other:

ƒ The digital inputs and outputs:

– input X6/SI1 (controller enable/inhibit)

– input X6/SI2 (pulse enable/inhibit)

– brake output X6/B+, B−

– output X6/SO ("safe torque off" active/inactive)

ƒ The circuit for the internal control

ƒ The final power stage
