3. Monitoring limit values and tolerances
4. Changeover and monitoring times
5. Stop responses after a monitoring function has responded
6. Assignment of safety-relevant inputs and outputs, i.e. which sources are supplying the
control signals for the NC monitoring channel , and where do the feedback signals go (for
the drive monitoring channel, this logical assignment must be programmed in the PLC, i.e.
there are no corresponding drive parameters).
Step 6:
Set the monitoring and save the data for all of the associated drives. Here, almost all data
entered under Step 6 are again entered in the "Drive machine data" screen. When the softkey
"Copy SI data" in the "Safety Integrated" screen is pressed, the settings from Step 5 are
automatically entered, with the exception of Points 2 and 6. Point 2 cannot be copied because
the drive always operates with the motor encoder and for a two-encoder system, has other
characteristic data than the encoder evaluated from the NC. The 6th point is not applicable on
the drive side. The following operating steps are therefore involved:
1. Press the softkey "Copy SI data" in the screen "Safety Integrated".
2. For each drive, enter the encoder configuration using the softkey "Adapt SI encoder". At
the same time, the data, copied under Point 1 in Step 6 can be subject to a visual check.
3. Initiate an NCK and drive reset using the appropriate softkey. In this case, component IDs
are also transferred from the drive to the NCK.
4. Press the softkey "Acknowledge SI data" in the "Drive configuration" screen. A dialog box
describing the function of the softkey then appears: After acknowledging with "OK", the
actual checksum of the safety-related data is then saved in both monitoring channels and
monitored for changes from this point onwards. Further, drive data is automatically saved
in a non-volatile fashion.
5. A dialog box is displayed on the screen requesting you to perform an acceptance test. This
dialog must be acknowledged. Now carry out the NCK reset and drive reset that are listed.
6. Activate SPL protection.
Step 7:
Issue a user agreement (see Chapter "User agreement (Page 92)")
● The safe limit positions and Safe Cams are now activated (provided that they have been
enabled, see Chapter "Enabling the safety-related functions (Page 98)"). This step can be
omitted if you do not wish to use either of these functions.
● The key-operated switch must be set to position 3 in order to issue a user agreement.
