1) Parameters 01-36(P.255), 01-37(P.256), 01-38(P.257) and 01-39(P.258) are used to start inverter gradually
without impact. And adjust the value to vary degrees of S shape acceleration / deceleration curve. When the
S shape acceleration / deceleration curve is started, the inverter will accelerate/decelerate with different
speed according to the primary acceleration/deceleration time.
2) When S shape acceleration/deceleration curve 3 is selected, the acceleration/ deceleration time will be longer,
as follows
3) When the selected acceleration time (01-06(P.7) or 01-22(P.44))≥01-36(P.255) and 01-37(P.256), the actual
acceleration time is as follows:
Actual acceleration time = the selected acceleration time +(01-36(P.255) + 01-37(P.256))/ 2
4) When the selected deceleration time (01-07(P.8) or 01-23(P.45))≥01-38(P.257) and 01-39(P.258), the actual
deceleration time is as follows:
Actual deceleration time = the selected deceleration time +(01-38(P.257) + 01-39(P.258))/ 2
