Error: During the initialization the power circuit could not be recognized
49
or was identified as invalid.
Error: Power circuit identification was changed; with a valid power circuit
this error can be reset by writing to SY.3. If the value displayed in SY.3
50 is written, only the power-circuit dependent parameters are reinitialized.
If any other value is written, then the default set is loaded. On some sy-
stems after writing Sy.3 a Power-On-Reset is necessary.
Error: Parameter value could not be written to the power circuit. Ack-

„Error, restart after reset".
39 It has been attempted to select a locked parameter set. Error !
The target position lies outside of the limit defined with the right software

limit switch. Error !
The target position lies outside of the limit defined with the left software
45
limit switch. Error !
Undervoltage (DC-link circuit). Occurs when the DC bus voltage drops
below the permissible value. Causes:
input voltage too low or instable
inverter rating too small
2
voltage losses through wrong cabling
the supply voltage through generator / transformer breaks down at very
short ramps
if a digital input was programmed as external error input with error mes-
sage E.UP.
3 One phase of the input voltage is missing (ripple-detection)
Watchdog for communication between operator/control card or operator/
93
PC has responded. The response to this warning can be programmed.
The motor temperature has exceeded an adjustable warning level. The
96 switch off time is started. The response to this warning can be program-
med. This warning can be generated only with a special power circuit.
This warning is triggered via an external input. The response to this
90
warning can be programmed.
The motor temperature is again below the adjusted warning level. The
91
switch off time is stopped.
88 The heat sink temperature is again below the adjusted warning level.
The temperature in the interior of the inverter is again below the warning
92
threshold.
98 OL counter has reached 0 %, the warning "overload" can be reset.
The cooling time after "Warning ! Overload during standstill" has elapsed.
101
The warning message can be reset.
A level can be defined, when it is exceeded this warning is output. The
89
response to this warning can be programmed.
Warning: electronic motor protective relay has tripped. The response to
97
this warning can be programmed.
The temperature in the interior of the inverter lies above the permissible
87 level. The switch off time was started. The programmed response to this
warning message is executed.
