NOTE
• To use terminal 4, the AU signal needs to be turned ON.
• To make compensation input for 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 setting of the voltage/current input selection switch. Incorrect setting may cause a
fault, failure, or malfunction. (Refer to page 349 for the setting.)

Input filter time constant 1 0 to 8
Set the primary delay filter time constant to the analog input
command. If the setting is too large, response becomes
slow.

Set the primary delay filter time constant to the external
speed command (analog input command).

Analog input offset
adjustment
100% 0% to 200%
Set offset for the analog speed input (terminal 2). The motor
is prevented from rotating due to noise in the analog input
or other factors when a zero speed command is given.
