MVP 2023 kratmel Posted March 5, 2019 MVP 2023 Report Share Posted March 5, 2019 What with communication cable shielding? Connected according to the manual? Is it shielded cable used for motor connection? Is it VFD and shielded motor cable correctly grounded? Is it communication OK when VFD is stopped?

MVP 2023 kratmel Posted May 6, 2019 MVP 2023 Report Share Posted May 6, 2019 If communication OK when VFD is stopped - your parameters and configs is OK. Is it terminator (120 Ohm resistor) present on both side of the line? Please also see this topic Quote Link to comment Share on other sites More sharing options...
