Tips:
When starting preset frequency is less than the starting frequency or starting preset holding frequency time is 0,
the starting preset frequency is invalid.
P1.07 Acc/Dec mode
Setting range: 0~3 [0]
0: Linearity
1: S-curve
2: Reserved
3: Reserved
Notes:
Linear Acc/Dec mode used for ordinary load: The output frequency increases or decreases according to a
constant rate. As shown in Figure. 5-1-5.
Figure. 5-1-5 Linear acceleration/deceleration
S-curve change output frequency slowly at start of acceleration or end of deceleration, in order to reduce
mechanism noise and shake, lash of start and stop. It is suitable for the load that needs descending torque at
low frequency, and short-time acceleration at high frequency, such as conveying belt.
