- AUXILIARY FUNCTION: It allows the aux output of the connector G7 to be active
under certain conditions. We can set it in the following way:
1) CURRENT GAIN: It is the logic board standard way of working. The output
AUX G7 is not used. (Jumper setting: 1-3; 2-4)
2) HYDRO CONTACTOR: The output AUX G7 commands the hydrodrive contactor.
It should be active during both forward and backward
directions and during release braking. The turning OFF
delay is programmable at "AUXILIARY TIME".
(Jumper setting: 1-2; 3-4)
3) BIMOT. CONTACTOR: AUX G7 output is activated when turning from off status to
running status and at the beginning of regenerative brak-
ing, and it is switched off when PWM is greater than 20%,
both statuses.
NOTE: It is necessary to adjust the jumper configuration on the chopper electronic
board depending upon previous program set. Mismatchings cause the power
section of the chopper to be damaged as well as mis functioning.
- For each setting we should set the jumpers (J 1, 2, 3, 4) configuration on the logic
board.
