NOTES
Changing the terminal function using any of Pr. 178 to Pr. 184 may affect the other functions. Make
setting after confirming the function of each terminal.
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different
setting may cause a fault, failure or malfunction. (Refer to page 6-178 for setting.)
