Step 5:
Set the monitoring function for all of the axes to be safely monitored.
Enter the following in the specified sequence in the "axis–specific machine data"
screen:
1. Axis characteristics (rotary or linear axis)
2. Measuring–circuit assignment, i.e. which encoder will supply the safety actual
value, what are the characteristics of this encoder and how it is mechanically
mounted.
3. Monitoring limit values and tolerances
4. Changeover and monitoring times
5. Stop responses after a monitoring function has responded
6. Assignment of safety–related inputs and outputs, i.e. which sources are supply-
ing the control signals for the NC monitoring channel and where do the feed-
back signals go (for the drive monitoring channel, this interlocking/logical as-
signment must be programmed in the PLC).
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 en-
coder". At the same time, the data, copied under Point 1 in Step 6 can be sub-
ject to a visual check.
3. Initiate an NCK and drive reset using the appropriate softkey. In this case, com-
ponent 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 acknowl-
edging 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 accep-
tance test. You must acknowledge this dialog box. Now carry out the NCK reset
and drive reset that are listed.
6. Activate SPL protection.
