COMBIVERT F5-A, -E, -H
Error: Undervoltage (DC-link circuit). Occurs, if DC-link voltage falls
below the permissible value. Causes:
input voltage too low or unstable
inverter rating too small
voltage losses through wrong cabling
the supply voltage through generator / transformer breaks down at
very short ramps
at F5-G B housing E.UP is also displayed if no communication takes
place between power circuit and control card.
jump factor (Pn.56) too small
if a digital input was programmed as external error input with error
message E.UP (Pn.65).
One phase of the input voltage is missing (ripple-detection)
Watchdog for communication between operator - PC or operator
- inverter has responded. The response to this warning can be
programmed.
The motor temperature has exceeded an adjustable warning level.
The switch off time is started. The response to this warning can be
programmed. This warning can be generated only with a special
power circuit.
This warning is triggered via an external input. The response to this
warning can be programmed.
The motor temperature is again below the adjusted warning level.
The switch off time is stopped.
The heat sink temperature is again below the adjusted warning level.
The temperature in the interior of the inverter is again below the
warning threshold.
Warning: no more overload, OL counter has reached 0 %, warning
„overload" can be reset.
The cooling time after "Warning! Overload during standstill" has
elapsed. The warning message can be reset.
This warning is output when the defined level is exceeded. Furthermore
the response to this warning can be programmed.
Warning: electronic motor protective relay has tripped. The response
to this warning can be programmed.
The temperature in the interior of the inverter is above the permissible
level. The switch off time was started. The programmed response to
this warning message is executed.
A level between 0 and 100 % of the load counter can be adjusted.
The warning is output on exceeding this level. The response to this
warning can be programmed.
The warning is output when the standstill continuous current is
exceeded (see technical data and overload characteristics). The
response to this warning can be programmed. The warning message
can only be reset after the cooling time has elapsed and A.nOL2 is
displayed.
