202 Operating Instructions ACTIVE 06/07
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 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

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 mains 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 DC-Link
Limitation
680.
C 00 10 Boost
The
Dyn. Voltage Pre-Control 605 accelerates the control
behavior.
C 00 20 Ilim
The output current is limited by the current limit value control-
ler or the speed controller.
C 00 40 Tlim
The output power or the torque are limited on 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 Fre-
quency
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.
