Key sequence
3-5-3 Selecting the Application (Setting V/f Patterns)
• Set the V/f pattern so that the motor output torque is adjusted to the required load torque.
• With the 3G3JE, either of the two patterns below can be selected as the pattern for V/f characteris-
tics.
• The 3G3JE has an automatic torque boost function. The suitable torque characteristics can be
obtained by simply selecting the load application.

application
Select for applications such as conveyers, where the load
torque is uniform regardless of the rotation speed and the
load moment of inertia is high.
Select for applications such as fans and pumps, where the
load torque is lower when the rotation speed is slower.
