• Be sure to perform V/f switching in the stop state. Switching is impossible during run. It takes 0.1
second before switching. Therefore, be sure to wait 0.1 second or more after inputting a switching
4
signal, and then start operation.
• When you want to use the vector control and V/f 5-point setting, select V/f1. When V/f2 to V/f4 are
selected, V/f constant is obtained, and thus making the vector control impossible.

• When you use an input terminal where a variety of functions can be assigned, you can link the
switching of torque limit or acceleration/deceleration time to V/f switching.
6
For operation panel run, you can also set the acceleration/deceleration time at <F504: Panel Acc/
Dec select>. For details, refer to [6. 27. 2].
