NOTES To use terminal 4, the AU signal needs to be turned ON.
To make compensation input for the multi-speed operation or remote setting, set Pr. 28 "Multi-
speed input compensation selection" = "1" (with compensation) (initial value "0").
After changing the Pr. 73 setting, check the voltage/current input switch setting. Incorrect setting
may cause a fault, failure or malfunction. (For the settings, refer to page 5-389.)
