Why is the LED scrolling on the ATV312? Product Line:
Altivar 312, Altivar 12 Environment:
All serial numbers Cause:
The scrolling LEDs mean the drive is in Local Operation mode. To switch into Local Programming, push and hold the ESC button for 2s. Then all three LED's will be flashing at the same time and the programming can be changed. When programming is finished, push and hold the ESC button again for 2s to enter into Local Operation again.
To switch back into Remote mode, push and hold the Mode button for 3s. Note - some programming is reset to factory defaults if you switch between Local and Remote. The drive is intended to be used for Local or Remote, not Local and Remote
