• Setting necessary parameters for communication
Communication related parameters must be set for PLC communication. parameters
n151 to n157 cannot be set during communication. Always set them prior to
performing communication.
* The slave does not respond to the command from the master when set to 0.
Monitoring run status from the PLC, setting/referencing of parameters, fault reset and
multi-function input reference can be done regardless of run command or frequency
reference selection.
Multi-function input reference from PLC becomes OR with input commands from S1
to S7 multi-function input terminals.
