6.4 Basic parameters 2
6.4.1 Switching motor characteristics via terminal input
: Base frequency 2
: Torque boost 2
: Motor electronic-thermal protection level 2
• Function
Use the above parameters to switch the operation of two motors with a single inverter and to select
motor V/F characteristics (two types) according to the particular needs or operation mode.
Note: The (V/F control mode selection) parameter is enabled only for motor 1. If motor 2 is se-
lected, V/F control will be given constant torque characteristics.

*Setting value of F170 depending on the end of Type-form. AN, WN : 60Hz, WP : 50Hz
■ Setting of switching terminals
The terminal for switching to motor 2 needs to be set, since this function is not assigned under the default
setting. Assign this function to an idle terminal.
The parameters to be switched depend on the particular identification number of the input terminal selection
function.
