•
When the protective door is open the operator can select either safe
operating stop or traverse with safely reduced speed at 2 m/min (axes) and
50 rpm (spindle) using the key-operated switch.
• When the protective door is closed all the drives are monitored for
maximum speed by Safety Integrated
• Testing the shutdown paths (with SPL: Test of the external STOPs and
forced checking procedure of the inputs and outputs).
i.e. Safety Integrated with SPL with contactless EMERGENCY STOP
Note
• This basic circuit must be adapted to the various safety zones (if
applicable) and the number of axes according to the machine
configuration.
• SI functions are used to safely monitor the drives for standstill or a
specific speed and to stop them safely in the event of an error.
7.2.1 Control and drive components
The configuration of the individual components is illustrated below.
The system requirements are described in the Description of Functions.

PLC I/Os
Fig. 7-2 Structure of the control and drive components
The MMC 103, NC572 and SIMODRIVE 611 digital components are used in
this example. The design must also be expanded to include a terminal block
with 16-bit I/O modules for the NCK side and additional S7 modules for the
PLC/drive side.
The additional operating elements (switches, buttons etc.) and the contactors
required for switching off the power are listed and described in more detail in
the relevant sections.
