All Delta Electronics frequency converters of different series have almost the same parameter sets related to Modbus communication. This article uses the CP2000 model as an example. (in other models, some parameters may be missing or have other addresses, but in general the settings are identical) | All Delta Electronics frequency converters of different series have almost the same parameter sets related to Modbus communication.
