Analog Ramp - Easy Electronics xLogic Micro PLC User Manual

1. The periodic time must be no less than 3 ms.
2. If the specific output is selected in the property dialog box of PWM block, then the output pin of PWM
function block cannot be linked as input to other blocks.
3. Q3, Q4 in the above dialog box are exactly corresponding to Q3, Q4 of ELC-12 CPU and Q5,Q6 of
ELC-22/26 and upgraded ELC-18 CPUs

6.5.29 Analog Ramp

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.
