•
The control method, V/f characteristics, and motor constants recorded in the Inverter can be
switched by setting “16” (motor switch command) for a constant from H1-01 to 06 (multi-function
inputs), and then inputting a signal while the motor is stopped.
•
The current motor selection can be monitored at a multi-function output terminal by setting “1C”
(motor selection monitor) for a constant from H2-01 to 03 (multi-function outputs).
•
Set the Basic (3) or Advanced (4) access level in the initialize setting A1-01 (access level).
•
The constants being used will changed as shown in the following table for the motor switch com-
mand.
