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.
Digit 3: 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.

ATTENTION: If the StepLogic sequence continues running and never stops while
Parameter E222 [Positioning Mode] is set to 2, 3 or 4, remove power to the drive and
swap the A and A (NOT) encoder channels.
