Signal Cause Remedy
Complete information on the messages is available in the List Manual.
F01611 Defect in a monitoring channel.
Fault value r0949 provides more de‐
tailed information.
The remedy depends on the fault value. The complete list of the fault
values is provided in the List Manual.
0: Stop request from processor 2.
1 … 999: Fault in data cross-check between processor 1 and process‐
or 2.
Details and remedy: Please refer to the List Manual.
1000: Check (watchdog) timer has expired.
When selecting a safety function, the signal changed too frequently.
The inverter monitors the signal to select a safety function after a signal
change.
If the signal state continues to change in shorter intervals than entered
in p9650, after the time 5 × p9650 the inverter outputs fault F1611:

Remedy:
● Check the F-DI wiring (contact problems).
● Resolve the contact problems or faults at the PROFIBUS master/
PROFINET controller.
The inverter terminates the monitoring and does not signal any faults
if the signal state remains stable before the time 5 × p9650 expires,
longer than p9650:

1001, 1002: Initialization error, change timer/check timer.
● Remedy: Switch off the power supply voltage of the inverter and
switch on again.
2000: Status of the STO selection for the two monitoring channels is
different.
Response to a discrepancy when STO is active (Page 226)
2001: Checkback signal of the safe pulse suppression for the two
monitoring channels is different.
