Why would the ATV58 be unable to run in keypad or terminal command even though the display says ready?
Not running with run command
Check the assignment of the logic inputs. If there is a logic input assigned to fast stop, the display will say ready even though the fast stop may be activated. In the fast stop mode, the drive will be prohibited from running. The logic input assigned to fast stop is active low, so make sure there is 24V on the input to deactivate it thus allowing the drive to run.
