■ Function
These parameters are used for setting when you want to switch up to four types of motors for an
inverter, or when you want to switch the motor V/f characteristics (four types) according to the
9
purpose or operation method.
V/f1 to V/f4 are switched by the input terminal signals.

6. [Advanced] How to use parameters
Switching two to four types of motor
characteristics
• <Pt: V/f Pattern> is valid only for V/f1.
When V/f2 to V/f4 are selected, V/f constant control is applied regardless of the setting of <Pt>.
• Do not switch the motors when <Pt: V/f Pattern> is set to "7" or "8".
• For the parameters that are selected when V/f1 to V/f4 are switched, refer to the following table.
