What can cause the ATV71 drive to run on power up with Logic input switch turned off?
Altivar 71, Altivar 61
All models and serial numbers
Drive state is RUN Drive is in terminal control. Logic input map shows LI1 is enabled. 0 volts is measured between COM and LI1. This logic input appears to be shorted internally. You will need to remove the Logic input terminal POD to trip the drive on a PRA condition. Now you can go into Menu 1.5 IO and change RRS reverse to LI2. Move the wiring from LI1 to LI2. Swap two motor wires on the load side of the drive. Check Logic input map.
