4.4 Communication specifications of the Mitsubishi inverter protocol
(computer link communication)
• Parameter setting, monitoring, etc. can be performed using Mitsubishi inverter protocol
• To make communication between the personal computer and inverter, setting of the communication specifications
must be made to the inverter in advance.
Data communication cannot be made if the initial settings are not made or if there is any setting error.
