E07
These inverter error messages are related to problems with the inverter braking group or the braking
resistor.
NO
Reinstate the connection
YES
Is the braking resistor
correctly connected to the
inverter?
Is the value of the braking
resistance correct?
Replace the braking
resistor
1
YES
Does the machine resume
correct operation after being
turned off for 1 minute?
YES
Probable interference. The
machine is OK
Replace the inverter
NO
NO
E07E06
Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) With the machine switched off, disconnect a resistor terminal from the inverter terminal block
and place the tester probes across it. The measured resistance should be 150 Ohm.
To reduce the occurrences of error E06, adjust inverter parameter b90, increasing its
setting from the default value to 20. This adjustment allows the inverter to increase its
use of the braking resistor.
