Basic Parameter Group 01
PARAMETER DESCRIPTION 74
Example: when the parameters are in default value (60 Hz system), the actual acceleration time from stop state to
60Hz in accordance with S shape acceleration/deceleration curve 3 is as follows:
01-36
(P.255)
01-37
(P.256)
Starting frequency
(
01-11(P.255)
)

Set acceleration time T1 = (01-09(P.20) - 01-11(P.13)) * 01-06(P.7) / 01-09(P.20)
Actual acceleration time T2 = T1 + (01-36(P.255) + 01-37(P.256)) * (01-09(P.20) - 01-11(P.13)) / 2 /
01-09(P.20)
So T1 = (60 - 0.5) * 5 / 60 = 4.96s (the actual acceleration time of linear acceleration)
Actual acceleration time T2 = 4.96 + (0.2 + 0.2) * (60 - 0.5) / 2 / 60 = 5.16s
Note: All calculations of acceleration/deceleration time are based on 01-09 (P.20).
