See Appendix D
and Appendix E for more information on applying StepLogic® function and Position StepLogic application.
Parameters L180...L187 are only active if P047 , P049 , or P051 [Speed Referencex] is set to 13 “Step Logic” or 16 “Positioning”. These parameters can be used to create a
custom profile of frequency commands. Each “step” can be based on time, status of a Logic input or a combination of time and the status of a Logic input.
Digits 1...4 for each [Stp Logic x] parameter must be programmed according to the desired profile. A Logic input is established by setting a digital input, parameters t062 ,
t063 , t065 ... t068 [DigIn TermBlk xx] to 24 “Logic In 1” and/or 25 “Logic In 2” or by using Bits 6 and 7 of A560 [Enh Control Word].
A time interval between steps can be programmed using parameters L190 ... L197 [Stp Logic Time x]. See the table below for related parameters.
The speed for any step is programmed using parameters A410 ... A417 [Preset Freq x].
The position for any step is programmed using parameters L200 ... L214 [Step Units x].
How StepLogic Works
The StepLogic sequence begins with a valid start command. A normal sequence always begins with L180 [Stp Logic 0].
Digit 1: Logic for next step
This digit defines the logic for the next step. When the condition is met the program advances to the next step. Step 0 follows Step 7. Example: Digit 1 is set to 3. When
“Logic In 2” becomes active, the program advances to the next step.
Digit 2: Logic to jump to a different step
For all settings other than F, when the condition is met, the program overrides Digit 0 and jumps to the step defined by Digit 3.
Digit 3: Different step to jump
When the condition for Digit 2 is met, this digit setting determines the next step or to end the program.
Digit 4: Step settings
This digit defines additional characteristics of each step.
Any StepLogic parameter can be programmed to control a relay or opto output, but you can not control different outputs based on the condition of different StepLogic
commands.
