Dear Rob,
Alarm #12 is for EEPROM Config KO.
Each time that you replace or re-install the steering sensor or the chopper (Motor Driver). You have to connect to the drive by console and adjust the steering sensor for it. For Bi-Motor fork lifts, some times it could become damage driver of one side if the steering sensor is not adjusted correctly.
I do not know if you have solved your problem or not. But I think the best solution could be done by having a programming console and check and adjusting every thing step by step. Let me know if you need more info or details.
Best Regards,
Have you checked the motor encoder outputs?
They should be able to cause most of those symtoms.
If memory serves, they are 80 count encoders.
I have a quick question to go along with your responce. Could you please explain the proper way to set up and learn the pot when a new one is installed?
Thanks in advance
mack sure the wires to the steer pot are not under pressure when you close the panel lid.they can get hanged up on the power cables when the cover dropps down into position. also how did you setup the steering pot.
