RAMP

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Limit the ascendance or descendance of a signal.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN	REAL				Input signal.
ASC	REAL				Maximum ascendance during time base.
DSC	REAL				Maximum descendant during time base.
TM	TIME				Time base.
RST	BOOL				Reset New start of the microprocessor..

Outputs

Output	Data Type	Range	Unit	Description
OUT	REAL			Ramp The gradual acceleration and deceleration of a stepping motor. This is essential if performance beyond the start/stop range is required. The slope of the ramp is a function of screw pitch, load, drive voltage and design, and motor. signal.

Remarks

• Parameters are not updated constantly.
  • They are taken into account only when the:
    • The block is called the first time.
    • Reset input (RST) is TRUE.
  • In these two situations, the output is set to the value of IN input.
• ASC and DSC give the maximum ascendant and descendant growth during the TB time base.
  • Both must be expressed as positive Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. numbers.

FBD Language Example

FFLD Language Example

• In the FFLD Language, the operation is executed only if the input rung (EN) is TRUE.
  • The output rung (ENO) keeps the same value as the input rung.
• The function is executed only if EN is TRUE.
• ENO keeps the same value as EN.
