In the safety program, logically combine all channel reset signals of channels that contain drive
objects with safety functions, with the "Internal Event ACK" signal for each drive object involved.
WARNING
Unexpected restart for safety-related acknowledgment without MCP reset!
If a STOP response is acknowledged in a safety-related fashion by the machine operator, but
without PROFIdrive RESET acknowledgment, then the part program is not canceled and is
continued with the acknowledgment. When the machine restarts unexpectedly, this can put
people in dangerous situations or cause material damage.
● In the safety program logically combine safe acknowledgment (PROFIsafe IEACK) with a
RESET at the machine control panel (PROFIdrive RESET).
Precondition
● PLC tags for the "Internal Event ACK" signal are added (Page 228) for each drive object.
