Figure 68 - S Curve
S Curve %
Sets the percentage of acceleration or
deceleration time that is applied to
ramp as S Curve. Time is added, half at
the beginning and half at the end of
the ramp.
Parameter Number 183
Access Rule GET/SET
Data Type UINT
Group Drive Advanced Setup
Units 1%
Minimum Value 0
Maximum Value 100
Default Value 0% disabled
Example:
Accel Time = 10 Seconds
S Curve Setting = 50%
S Curve Time = 10 x 0.5 = 5 Seconds
Total Time = 10 + 5 = 15 Seconds
1/2 S Curve Time
2.5 Seconds
Total Time to Accelerate = Accel Time + S Curve Time
Accel Time
10 Seconds
50% S Curve
Target 2

1/2 S Curve Time
2.5 Seconds
Boost Select
Sets the boost voltage (% of
Parameter 131 (Motor NP Volts)) and
redefines the Volts per Hz curve.
Active when Parameter 225 (Torque
Perf Mode) = 0 (V/Hz). Drive may add
additional voltage unless Option 5 is
selected.
See Table23 for details.
