■ Using S-Curve Characteristics during Acceleration/Deceleration
Using S-curve characteristics to smooth acceleration and deceleration minimizes
abrupt shock to the load.
Note: 1. Setting S-curve characteristics will lengthen accel/decel times as follows:
Accel Time = Selected Accel Time + (C2-01 + C2-02)/2
Decel Time = Selected Decel Time + (C2-03 + C2-04)/2
2. Set longer S-curve times using PM Open Loop Vector Control.
Setting Example
S-curve characteristics when switching between forward and reverse are illustrated
in Figure 4.22.

◆ V/f Pattern Selection: E1-03
This parameter is only available when using V/f Control. It allows the user to set
the V/f pattern and drive output voltage as required. When running a high-speed or
other type of special-purpose motor, use this function to fine tune the amount of
torque required for the load. The V/f pattern can be selected between 15 fixed V/f
patterns or 1 user programmable V/f pattern.
