(CU/MM)
4 Transition time from STOP F to STOP A (CU/MM)
5 Safe brake control (CU/MM)
6 Enable, safe motion monitoring
Additional diagnostic values (from 1000 onwards):
Value Description of errors
1000 Check (watchdog) timer has expired
1001 Change timer initialization error
1002 Check (watchdog) timer initialization error
2000 Error when comparing the SH terminals
2001 Error when comparing the feedback signals
DIAG_U and DIAG_L
r9798 SI actual checksum SI parameters (Control Unit)
Displays the checksum over the checked Safety Integrated parameters on the
Control Unit (actual checksum).
Unit: Default value:
– –
r9799 SI reference checksum SI parameters (Control Unit)
Sets the checksum for the checked Safety Integrated parameters on the Con-
trol Unit (reference checksum).
Unit: Default value:
– 0000 hex
The actual checksum (r9798) calculated by the CU must be entered into the refer-
ence checksum p9799. This therefore acknowledges the safety commissioning on
the Control Unit.

Change timer in the MM has been active too long
When starting the change timer, MM has not set
the "timer running bit"
The CU had not started the check (watchdog)
timer although in MM the change timer is presently
running
Status of the SH terminals on the Control Unit and
Motor Module are different.
Status of the feedback signals of the safety shut-
down paths on the Control Unit and Motor Module
are different.
