Please wait approximately 20 s before the machine is started after switching on the main switch.
In the event of a fault or power failure, switch off the main switch and check the cause (fuse). Before
switching on again, switch of the main switch for 60s.
Always keep the connectors clean and tight and secure. Water or moisture in the
connector may cause serious damage to the electronics. Do not use water jet or high
pressure cleaners to clean the converter and the machine. Max. Water pressure 4 bar.
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 Intermediate circuit is charged
flashing
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

Measure
- Switch on main switch
- Use adapter calbe type FU06543
- Check supply cable (cable interrupted)
- Check mains voltage (fuse)
- W ait
- 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)
