7 Changeover of communications
I
n order to perform the inverter operation through the communication (by command data and operation data),
the communication should be made valid under the condition that 1–3 of "H30: Serial link (Function
selection)” has been selected. (The reading and writing of function data and functions are possible in any time
regardless the communication valid or invalid).
Warning
Be sure to check no run command because of sudden start when valid/invalid
communication is changed over, while a run command through RS485 or external signal
terminals is remained.
There is a fear of failure.

7-1 Changeover method for communication valid/invalid
The changeover of the communication valid/invalid can be performed by the multi-function command terminals
(terminals X1-X9) on the inverter. However, it is necessary to set the inverter’s multi-function command input
terminals (E01 – E09: X1–X9 terminals function) to the link operation selection (Data 24). If the multi-function
command terminals have not been set to the link operation selection, the communication becomes valid
automatically.

Note

：
1) Since all memories are initialized at switching power supply on, the command data and operation data
must be write again from the upstream units.
2) Even when the communication is invalid, the writing of command data and operation data is valid, but it
is not reflected by SW1
・
SW2. The changeover without shock is possible by the way where the data are
set previously during the communication invalid mode at first, then the mode is changed over to the
communication valid mode.
