COMBIVERT R6-S
Adjusted monitoring time (Watchdog) of communication between
operator and PC / operator and inverter has been exceeded.
After reset the operation is again possible (without storage in the
EEPROM)
Is triggered, if a digital input is being programmed as external error
input and trips.
Error: Load-shunt relay has not picked up, occurs for a short time during
the switch-on phase, but must automatically be reset immediately. If
the error message remains the following causes may be applicable:
- load-shunt defective
- input voltage wrong or too low
- high losses in the supply cable
One or more phases are missing.
No longer overheating in the interior E.OHI, interior temperature has
fallen by at least 5° C, error can be reset
no overload, OL counter reaches 0 %; a cooling down phase must
be awaited after error E.OL. This message appears upon completion
of the cooling phase. The error can be reset now. The inverter must
remain switched on during the cooling phase.
Occurs, if the specified peak current is exceeded. Causes:
- acceleration ramps too short
- short-circuit at the output
- ground fault
- overload too high (e.g., deceleration ramp too high at the inverter)
- wrong parameterization
Overtemperature of power module. Error can only be reset at E.nOH,
if the temperature has dropped by at least 5° C.
Causes:
- insufficient air flow at the heat sink (soiled)
- ambient temperature too high
- ventilator clogged
Overheating in the interior: error can only be reset at E.nOHI, if the
interior temperature has dropped by at least 5 °C.
Overload, error can only be reset at E.nOL, if OL-counter reaches
0% again. Occurs, if an excessive load is applied longer than for the
permissible time (see technical data). Causes:
- overload in the application
Voltage in the DC-link circuit too high. Occurs if the DC-link voltage
exceeds the permissible value. Causes:
- input voltage too high
- interference voltages at the input
General power circuit error (e.g. switch-mode power supply or loading
shunt relay)
During the initialization the power circuit could not be recognized or
was identified as invalid.
Power circuit identification was changed; with a valid power circuit this
error can be reset by writing to SY.03. If the value displayed in SY.03 is
written, only the power-circuit dependent parameters are reinitialized.
If any other value is written, then the default set is loaded. On some
systems after writing Sy.03 a Power-On-Reset is necessary.
