• Function
Use the above parameters to switch the operation of 4 motors with a single inverter and to select motor V/f
characteristics (1 to 4) according to the particular needs or operation mode.
[Switching methods]
Terminals are used for this switching.
Note: The setting of parameter RV (V/f control mode selection) is valid only when V/f1 is selected. If
V/f2,V/f3 or V/f4 is selected, V/f control is performed in constant torque mode. Do not switch motors
when the parameter RV (V/f control mode selection) is set at , . For parameters selected when
changing V/f characteristics (1 to 4), refer to table on the next page.
Note: Refer to Section 5. 8 XN (Base frequency 1) for H, H and H,
Section 5. 8 XNX (Base frequency voltage 1) for H, H and H,
Section 5.7 XD (Manual torque boost) for H, H and H,
and Section 5.14 VJT (Motor electronic thermal protection level 1) for H, H and H,
respectively.
