Pr. 29		Function	Description
Setting
		Linear	Acceleration is made to the set frequency linearly.
0		acceleration/
			(Factory setting)
		deceleration
			For machine tool spindle applications, etc.
			Used when acceleration/deceleration must be made in a short
		S-shaped	time to a high-speed region of not lower than the base frequency.
			Acceleration/deceleration is made in a pattern where fb (base
1		acceleration/
			frequency) acts as the inflection point of an S shape, and you can
		deceleration A (*)
			set the acceleration/deceleration time which matches the motor
			torque reduction in the constant-output operation region of not
			lower than the base frequency.
			For conveyor and other load collapse prevention applications, etc.
		S-shaped	Since acceleration/deceleration is always made in an S shape
2		acceleration/	from f2 (current frequency) to f1 (target frequency), this function
		deceleration B	eases shock produced at acceleration/deceleration and is
			effective for load collapse prevention, etc.
	CAUTION			2

*As the acceleration/deceleration time, set the time taken to reach the Pr. 3 "base frequency" value, not the Pr. 20 "acceleration/deceleration reference frequency" value. For details, refer to page 59.
