Default:

Min/Max:

Display:
4 Digits
Parameters A140-A147 are only active if
[Speed Reference] is set to 6 “Stp Logic”.
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 0-3 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
“Logic In1” and/or 24 “Logic In2”.
A time interval between steps can be programmed using parameters
See the table below for related parameters.
The speed for any step is programmed using parameters
How StepLogic Works
The StepLogic sequence begins with a valid start command. A normal sequence always begins with
A140 [Stp Logic 0].
Digit 0: 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 0 is set 3. When “Logic In2” becomes active, the
program advances to the next step.
Digit 1: 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 2.
Digit 2: Different Step to Jump
When the condition for Digit 1 is met, the Digit 2 setting determines the next step or to end the program.
