Using DI to modify G120/G120C frequency

heynevets Posts: 8 Rating: (0)	Dear friends, I am trying to use G120 or G120C to replace Fuji inverters in a customer project. The Fuji inverters, however, offer the feature that the user can modify the motor RPM with DIs. For example, by activating DI0 the controller will add 0.5 Hz to the RPM while activating DI1 will subtract 0.5 Hz. I have skimmed over the free function blocks for G120 and did not see obvious solutions. I was wondering if CU240, CU250S, or G120C can reach the same function Sincerely, Steven

heynevets Posts: 8 Rating: (0)	Dear Marcjan, I read through the literature. The function, however, seems to accelerate/decelerate depending on the length the signal presents. Is it possible to modify the RPM on a discrete basis? for example, add 30 rpm when detecting arising edge of DI0 Thank you again, Steven
