Sets the time to accelerate from 0 to maximum frequency.
Sets the time to decelerate from maximum frequency to 0.
Sets the time for the Fast Stop function.
The S-curve can be controlled at the four points shown below.

Output Frequency
C2-01
Sets the gain for the automatic torque (voltage) boost function and helps to
produce better starting torque. Used for motor 1.
1: 2.0 kHz 1: Fc = 2.0 kHz
2: 5.0 kHz 2: Fc = 5.0 kHz
3: 8.0 kHz 3: Fc = 8.0 kHz
4: 10.0 kHz 4: Fc = 10.0 kHz
5: 12.5 kHz 5: Fc = 12.5 kHz
6: 15.0 kHz (12.0 kHz)
7: Swing PWM1 (Audible sound 1)
8: Swing PWM2 (Audible sound 2)
9: Swing PWM3 (Audible sound 3)
A: Swing PWM4 (Audible sound 4)
Determines the proportional gain for the carrier frequency.
