Re: How do I reset the encoder on my okuma MC-4VEA with a 5020m Controller
In your System Parameters, you need to go to the PR Zero Offset and shift the encoder position by the amount that you are off. It will give you a "Power on effective parameter set" alarm which requires a reboot. Once you do that, you will be in the new shifted position.
It's a good idea to write the number down first so that you can go back to it if you go the wrong direction.
Best regards,
PS> Your original Parameters for stroke, Zero, etc. should be in the back of the machine in the electrical cabinet recorded on the Management data card for reference.
Experience is what you get just after you needed it.
