DA11Ramp
D = Device(anpos-camming-camming2)
A = Action functions
The purpose of the DA11Ramp function is to build a ramp with an input set-point and acceleration and deceleration parameters.
This function can be used in the setting of speed without using a device.
IMPLEMENTATION
DA11Ramp (Setpoint, Acceleration, Deceleration, Start, Output, State)
Parameters:
IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
---|---|---|---|---|
IN | GLOBAL | Setpoint | L | Set-point (Um/s) |
IN | GLOBAL | Acceleration | L | Acceleration value (Um/s²) If 0, in acceleration ramp, the adjusting output does not change. |
IN | GLOBAL | Deceleration | L | Deceleration value (Um/s²) If 0, in deceleration ramp, the adjusting output does not change. |
IN | GLOBAL | Start | F | Run adjustment flag. If 0 the setting is disabled and the Setpoint value is copied to the Output value. |
OUT | GLOBAL | Output | L | Output value of the adjustment (Um/s) |
OUT | GLOBAL | State | B | Adjustment mode 0 = disabled / set-point is reached 1 = active adjustment in acceleration ramp -1= active adjustment in deceleration ramp |
Example
Adjustin output bringing the value of 1000, starting from 0, with ramp of 10 seconds.
IF Start Setvel = 1000 Acc = 100 Dec = 100 Run = 1 ENDIF DA11Ramp (Setvel, Acc, Dec, Run, Outvel, State)
Operation notes
-
The function manages the setpoint changes and the acceleration and deceleration time changes “on the fly”.
-
If the value of acceleration or deceleration is/or becomes 0 (ZERO), the value of the control output remains unchanged. For example, is used to stop a ramp to take it up.
-
Upgrading of the adjustment output occurs at each call of the function, so the higher the time between two calls (cycle task) and the higher the relative vector.
