1-1 Features
- A host unit can be connected up to 31 inverters.
- Because a common protocol for FRENIC5000G11S/P11S series is adopted, the similar program in host
unit can operate all inverter of the series. (The parameter specifications may differ for each unit type.)
- Because adopting the transmission frame of fixed length, the program on the host is facilitated.
- The optional transmission frame can shorten the communication time for the operation commands and
setting frequency required high response.
