A149 [S Curve %]
Sets the percentage of acceleration or deceleration time that is applied to the ramp as S Curve. Time
is added, 1/2 at the beginning and 1/2 at the end of the ramp.
Values Default: 20%
Min/Max: 0/100% (A setting of 0% disables this parameter.)
Display: 1%
Example:
Accel Time = 10 Seconds
S Curve Setting = 50%
S Curve Time = 10 × 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
50% S Curve
Target
Target/2
Accel Time
10 Seconds
1/2 S Curve Time
2.5 Seconds
Total Time to Accelerate = Accel Time + S Curve Time
100% S Curve
Target
S-Curve Time = Accel Time
A150 [PID Trim Hi]
Sets the maximum positive value that is added to a PID reference when PID trim is used.
Values Default: 60.0 Hz
Min/Max: 0.0/320.0 Hz
Display: 0.1 Hz
A151 [PID Trim Lo]
Sets the minimum positive value that is added to a PID reference when PID trim is used.
Values Default: 0.0 Hz
Min/Max: 0.0/320.0 Hz
Display: 0.1 Hz
