7.7.4 Definitions and effects in the NC
The motion control in the NC is linked to the Safety Integrated Functions in the drive via the SIC
status signals. This avoids that subsequent responses are initiated in the NC as a result of
safety stops in the drive.
Example: The motion control in the NC responds to the drive STOP responses by no longer
issuing additional setpoints for the path, for example. As a consequence, alarms to be
acknowledged are avoided, such as "Contour monitoring" or "Positioning monitoring".
The corresponding status bits from S_ZSW1 (or S_ZSW1B) are used to emulate the safety stop
responses in the NC.
