F-DI configuration
The signal states on the two terminals of an F-DI are then monitored whether they attain the
same logical signal state within the discrepancy time.
For example, the unavoidable delay caused by mechanical switching operation can be
adapted via parameters. The time within which the selection or deselection must be
performed in both monitoring channels in order to qualify as "simultaneous", is specified with
p9650.
For internal faults or limit value violations, the drive-internal safety functions issues safety
faults.
1. Interconnect signal source p9620 for STO, SS1 or SBC to the Control Unit.
Only the fixed zero and digital inputs DI 0 ... 7, 16, 17, 20 and 21 are permissible as
signal sources.
2. Enter a discrepancy time in the "Discrepancy time" (p9650) field.
3. Enter a time for the input filter (debounce time) in the "F-DI input filter" (p9651) field.
The debounce time is rounded off to whole ms and then accepted. This debounce time
applies for the F-DIs and the readback input for the forced checking procedure. The
debounce time specifies the maximum time an interference pulse can be present at F-DIs
before being interpreted as a switching operation.
PROFIsafe configuration
The PROFIsafe address is required for control of the safety functions via PROFIsafe.
1. Click the icon
The properties of the PROFINET interface are displayed in the Inspector window. The
"Cyclic data traffic" setting range is active. Here you define the telegrams for the drive
objects.
2. Click the <Add telegram> entry in the telegram configuration of "Drive axis_x".
3. Select the "Add safety telegram" option in the drop-down list of the entry:
Startdrive then inserts the "Safe actual value" and "Safe setpoint" lines. The relevant
PROFIsafe telegrams are preassigned.
4. Open the new "Safe setpoint" screen form (for Drive axis_x) in the Inspector window.
5. Correct the PROFIsafe address of the drive in the "F-address" field.
6. In the function view, switch back to the "control" screen form.
The value of the F-address is displayed in the "PROFIsafe address" (p9610) field. A
preassigned PROFIsafe telegram is displayed in the "PROFIsafe telegram no." drop-
down list.
7. Click "Accept values" to transfer the telegram from the default settings into the Safety
programming.
8. Select the desired stop response for a failure of the PROFIsafe communication in the
"PROFIsafe failure response" (p9612) drop-down list.
