Stay as close as possible to the converter during the update process. This way you will gain maximum transfer
speed and signal strength. If you notice the transfer is stuttering or slowing down you might be too far away
from the converter or something is jamming the connection.
Downloading the update file to the converter will take approximately one minute. During this time period the
process can be aborted without any risk. Once the download is finished the converter will start installing the
update. This process will take about another minute.
Don't disconnect the converter from the mains supply during this time!
If the process gets interrupted by a mains voltage dropout the converter will try to install the update two more
times. If these tries fail the display will show "invalid firmware". In this case please contact WEKA, we can help
you to restore the converters firmware.
2.2 Frequency converter FU6 C (Connect)
Status and error outputs are showed to the user via an LED attached to the frequency converter.
Status display
If there is a status change the green LED on the side of the converter flashes/shines. The number of pulses
after a longer break allows the assignation of the status according to following chart:
Status code Meaning
green off Frequency converter without
voltage supply
green flashing Intermediate circuit is charged
Frequency converter waits for
machine
Service intervall exceeded
green on Frequency converter ready
Failure display
If a failure occurs the red LED on the side of the converter flashes/shines. The number of pulses after a longer
break allows the assignation of the status according to following chart:
Status code Meaning
red Low voltage
permanent on
red 1x pulse Over temperature motor
red 2x pulse Over temperature
frequency converter
red 4x pulse Overcurrent
red 5x pulse Overload
red 6x pulse Encoding error
red 7x pulse Over current power modul
Measure
- Switch on main switch
- Use adapter calbe type FU06543
- Check supply cable (cable interrupted)
- Check mains voltage (fuse)
- Wait
- Connect machine
- Check connectors of machine and converter for dirt and
damages
- Bring converter to service station
- Converter can be used
Measure
- Increase wire cross section (extension cord)
- Check supply cable (cable interrupted)
- Use a generator with more power
- Increase water flow (cooling of motor or converter is too low;
water temperature is too high)
- Check hose connection
Never use waste water for cooling!
- motor stops, motor has been used in the overload range
- Check motor cable and plug connection for damages (short
circuit)
- Reduce machine load, motor is operated in the overload
range
- Check plug contacts of machine and frequency converter for
dirt and damages
- Update frequency converter (encoding unknown)
- Check motor cable and connectors for damages (short circuit)
