Inverter not OK

¿Qué significa 0106 ?

The V3F25/18 drive is prevented from operating until this fault is corrected. This indicates a general issue with the inverter's internal operation or its external control signals and feedback.

• Loose or incorrect connections of the tachometer and thermal switch (XM2).
• The value for Tacho fault counter (6_35) parameter may be too sensitive.
• LBR LED does not light.
• LBR lights but LBE is not activated at start (check parameter 6_38).
• MLB is 'shutdown' (check voltage in supply and X10/16 in MLB for +24V).

1. 1

   Check connections of tachometer and thermal switch (XM2).

2. 2

   If Tacho fault counter (6_35) parameter is too sensitive, turn the elevator to RDF and back to Normal to reset it.

3. 3

   If LBR LED does not light, refer to AS-11.65.008 and circuit diagrams.

4. 4

   If LBR lights but LBE is not activated at start, check parameter (6_38).

5. 5

   If MLB is 'shutdown', check voltage in the supply and at terminals X10/16 in MLB (+24V).

6. 6

   Remove the U REF2 jumper.
