5.5.29 Analog Ramp

Fashion:
Short Description:
The Analog Ramp instruction allows the output to be changed from the current level to a selected level at
a specified rate.
Connection Description
Input En A change in the status from 0 to 1 at input EN (Enable) applies the start/stop level (Offset "B"
+ StSp) to the output for 100 ms and starts the ramp operation to the selected level.
A change in the status from 1 to 0 immediately sets the current level to Offset "B", which
makes output AQ equal to 0.
SeI = 0: The step 1 (level 1) is selected.
Input Sel
SeI = 1: The step 2 (level 2) is selected.
A change in status of Sel causes the current level to start changing to the selected level at the
specified rate.
A change in the status from 0 to 1 at input St (Decelerated Stop) causes the current level to
Input St
decrease at a constant rate until the start/stop level (Offset "B" + StSp) is reached. The
start/stop level is maintained for 100 ms and then the current level is set to Offset "B", which
makes output AQ equal to 0.
Level1 and Level2: Levels to be reached; value range for each level: -10,000 to +20,000
parameter
MaxL: Maximum value that must not be exceeded.
Value range: -10,000 to +20,000
StSp: Start/Stop offset: value that is added to Offset "B" to create the start/stop level. If the
Start/Stop offset is 0, then the start/stop level is Offset "B").
Value range: 0 to +20,000
Rate: Speed with which level 1, level 2 or 0ffset is reached. Steps/seconds are issued.
Value range: 1 to 10,000
A: Gain
Value range: 0 to 10,00
B: Offset
Value range: +- 10.000
p: Number of decimal places
Value range: 0, 1, 2, 3
