Setting Items And Set Data - Mitsubishi Electric 800 Series Instruction Manual

Caution
 Always set the communication check time interval before starting operation to prevent hazardous conditions.
 Data communication is not started automatically but is made only once when the computer provides a communication request.
If communication is disabled during operation due to signal cable breakage etc., the inverter cannot be stopped. When the
communication check time interval has elapsed, the inverter will trip (E.SER).
The inverter can be coasted to a stop by switching ON the RES signals or by switching the power OFF.
 If communication is broken due to signal cable breakage, computer fault etc., the inverter does not detect such a fault. This
should be fully noted.
