6.4.2. THE INVERTER DISPLAY SHOWS E6 OR E7
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
inv erter?
Is the v alue of the braking
resistance correct?
Replace the braking
resistor
1
YES
Does the machine resume
correct operation af ter being
turned of f f or 1 minute?
YES
Probable interf erence. The
machine is OK
Replace the inv erter
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 turned off, disconnect one of the resistor wires from the inverter terminal
block and place the tester probes across the resistor. The measured resistance should be 150
Ohm.
To reduce the occurrences of error E06, it is possible to adjust the following inverter
parameter:
• On model J100: A38;
• On model SJ100: b90;
by increasing its value. This adjustment enables the inverter to increase the use of the
braking resistance.
