Can you switch between 2 wire control and 3 wire control using a logic input?
Issue:
Change between 2 wire control and 3 wire control with logic input.
Product Line:
Altivar 61, ATV61
Environment:
All models, All serial numbers.
Cause:
none
Resolution:
The drive must be programmed as either 2 wire or 3 wire control. There is no way to change this without both programming and wiring changes to the drive.
2 wire control - LI1 is run forward. The default programming is a transition of LI1 from low to high in order to run. This can be changed to Level switching. LI1 must stay closed for the drive to run.
3 wire control - LI1 is stop (NC contact) and LI2 is run forward. A momentary or maintained closure of LI2 causes the drive to run forward. LI1 (stop) needs to be opened in order to stop the drive.
