Fig 6-2-5 Soft start function
T1 and T2 are actual acceleration/deceleration time, the unit is ms.
Actual acceleration time T1=Po109×target speed/rated speed
Actual deceleration time T2=Po110×target speed/rated speed
6.2.3 S curve smoothness function
During the process of acceleration/deceleration, the rotation speed is unsteady. So add S curve
acceleration/deceleration command into speed command to make rotation speed of motor more smooth.
