LC - Control Setting Parameters
Proportional speed control gain during acceleration and high speed.
Proportional speed control gain during deceleration and low speed.
Proportional speed control gain for pre-torque.
In most cases it is not necessary to adjust the proportional gain. However, if a
vibration is felt in the car during the pre-torque phase this gain can influence
it. Try values of 500, 1000, 4000, and 6000 to determine whether or not there
is any influence. In some cases, a higher value may actually provide a more
smooth response.
Refer to Section 5.12.2 for additional information regarding pretorque.
