However in 420, i can just find 1 DO which i am using to energize external relay to have trip status. Now, i don't know how to energize a 2nd relay when VFD in in RUN condition. Pleae help. Thanks..

Hi, the Micromaster MM420 only has 1 digital relay output, please see theDifferences in Micromaster Family chart here. There is ONE option, if you are not using the MM420 analogue output, you can convert it to act like a digital output. See theFAQhere Best regards, Graeme
