240 Operating Instructions ACU 09/08
A decimal value is displayed, indicating the status of the digital signals in bits after
conversion into a binary figure.
Example: Decimal figure 33 is displayed. Converted into the binary system, the
number reads OOIOOOOI. Thus, the following contact inputs or out-
puts are active:
− Control signal at digital input or output 1
−
Control signal at digital input or output 6
20.3 Controller Status
The controller status can be used to establish which of the control functions are ac-
tive. If a several controllers are active at the time, a controller code composed of the
sum total of the individual codes is displayed. The display of the controller status by
the control unit and the light-emitting diodes can be parameterized via the
Controller
status message
409.
Coding of the controller status
CXXXX ABCDE
⏐ ⏐
Controller code Controller abbreviation
Code Controller Status
C 00 00 - No controller active.
C 00 01 UDdyn
Voltage controller is in the rise phase according to
Operation
mode
670
.
C 00 02 UDstop
The output frequency in the case of a power failure is below
the
Shutdown threshold
675.
C 00 04 UDctr
Failure of the mains voltage and power regulation active ac-
cording to
Operation mode
670
of the voltage controller.
C 00 08 UDlim
The DC link voltage has exceeded the
Reference UD limita-
tion
680
.
C 00 10 Boost
The
Dyn. voltage pre-control
605 accelerates the control
system.
C 00 20 Ilim
The output current is limited by the current limit value con-
troller or the speed controller.
C 00 40 Tlim
The output power or the torque is limited by the speed con-
troller.
C 00 80 Tctr
Switch-over of field-orientated control between speed and
torque-controlled control method.
C 01 00 Rstp
The
Operation mode
620 selected in starting behavior limits
the output current.
C 02 00 IxtLtLim Overload limit of the long-term Ixt (60s) reached, intelligent
current limits active.
C 04 00 IxtStLim Overload limit of the short-term Ixt (1s) reached, intelligent
current limits active.
C 08 00 Tclim
Max. heat sink temperature TK reached, intelligent current
limits of
Operation mode
573 active.
C 10 00 PTClim
Max. motor temperature reached, intelligent current limits of
Operation mode
573 active.
C 20 00 Flim
The reference frequency has reached the
Maximum frequen-
cy
419. The frequency limitation is active.
Example: The controller status is displayed
C0024 UDctr Ilim
The controller status results from the hexadecimal sum of the controller codes
(0004+0020 = 0024). At the same, the power failure regulation and also the current
limitation of the speed controller are active.
