9.5 Faults
9.5.1 Status messages
When a status message is generated, the
fault icon is displayed in the RUN operating
mode. In addition, the fault alarm contact St
is activated.
The possible cause of the fault is indicated
by the
STAT parameter reading under F0 to
F15 .
Note:
− The F4 status message ('Actuator
transit time exceeded') is only gen -
erated when a fault occurs and
when P13 ≠ OFF.
− The status messages F6 ('Min. value
for PST not reached') and F7
('Max. value for PST exceeded') are
only generated when a fault occurs
and when
P12 = YES.
− The F10 status message indicates
that one of the error messages E0
to E10 has been generated.
Example:
F2 : Limit of maximum
rotary motion (P26)
exceeded
Refer to the parameter list (section 13.1) for
possible causes and the recommended ac-
tion.
9.5.2 Error messages
When an error message is generated, the
fault icon is displayed in the
RUN operating
mode.
The possible cause of the fault is indicated
by the ERR parameter reading under
E0 to
E10 .
If an error E0 to E8 exists, all contacts (A, B,
C and St) respond for reasons of safety.
Error
E9 (device error 1) causes a wire break
(contact B) to be additionally signaled to
meet requirements of DIN EN 60947-5-6.
Error E10 (device error 2) causes the switch-
ing position to be displayed unchanged.
Example:
E0: No initialization
Refer to the parameter list (section 13.1 and
section 13.2) for possible causes and the
recommended action.
