Parameters
– Compensation (%): Terminal 2 input
Example
When Pr. 73 = "5"
By the terminal 1 (main speed) and terminal 2 (auxiliary) input, the setting frequency is set as shown
in the figure below.
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 5-255.)
