Function

Use the above parameters to switch the opera tion of 4 motors with a single inve rter and to select motor V/f

characteristics (1 to 4) according to the particula r 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. I f

V/f2,V/f3 or V/f4 is selected, V/f control is perfo rmed in constant torque mode. Do not switch motors

when the parameter RV (V/f control mode sel ection) 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 a nd 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.

• Function

This parameters reduces the ratio of

XNX

(base frequency vortage 1) /

(base frezuency 1) by selecting

V/f ratio switching (input terminal function 152(positive logic) or 153(negative logic)).
