My machine took a large bump while it was powered up. Operator dropped a 10mm plate flat onto the table near the rear mounted control box.
Now the keypad reads “communication Error with Inverter”
I suspect the VFD got damaged. If I can’t replace the unit with a exact model match I will need to swap out the VFD and control the spindle with either a pot or +/- 10v.
2 questions:
How do I disable MODBUS in the parameters ?
And
How can I connect the new VFD to +/- 10v on the M24 board ?
Thanks
