How can I check the logic inputs are working on an ATV312 drive?
Customer is not sure if the inputs are working. Drive is not running.
Altivar 312, ATV312
Go under the SUP menu to LIA-. Under LIA-, select parameter LIS (not LI5A). This will show the Logic inputs from LI1 to LI6. The dash mark will be high (closed) or Low (open). See the attached page from the programming manual, BBV46385 as reference.
