For the CNC-axes of the SINUMERIK 828, both the Safety Integrated basic functions (STO, SS1, SBC) and the extended Safety Integrated functions of SINAMICS can be used. The Safety Integrated basic functions are directly controlled via terminals. A SINAMICS S120 TM54F Terminal Module is required for controlling the extended Safety Integrated functions.

For simple positioning tasks, e.g. revolvers, loading systems or tool magazines that require no coordination with the CNC part program, it is possible to connect two auxiliary axes to the SINUMERIK 828D via the I/O interface based on PROFINET using a SINAMICS CU310-2 PN or CU320-2 PN.

The Safety Integrated basic functions of the SINAMICS system can be utilized for these CNC auxiliary axes. The Safety Integrated basic functions are selected by hardware and in 2 channels via terminals on the CU310-2 PN/CU320-2 PN and the Motor Module.

A partially automated acceptance test is provided in SINUMERIK Operate for acceptance testing Safety Integrated functions. All measured data and traces are logged and can be printed out in an acceptance report.
