Appendix E StepLogic, Basic Logic and Timer/ Counter Functions

StepLogic Using Timed Steps

To activate this function, set Parameter 138 (Speed Reference) to Option 6

(StpLogic). Three parameters are used to configure the logic, speed reference, and

time for each step.

• Logic is defined using Parameters 240…247 (StpLogic x)

• Preset Speeds are set with Parameters 170…177 (Preset Freq x)

• Time of operation for each step is set with Parameters 250…257 (StpLogic

Time x)

The direction of motor rotation can be forward or reverse.

StepLogic Sequence

• Sequence begins with a valid start command

• A normal sequence begins with Step 0 and transitions to the next step

when the corresponding StepLogic time has expired

• Step 7 is followed by Step 0

• Sequence repeats until a stop is issued or a fault condition occurs

StepLogic Using Basic Logic

Functions

Digital input and digital output parameters can be configured to use logic to

transition to the next step. Logic In1 and Logic In2 are defined by programming

Parameters 151…154 (Digital In x Sel) to Option 23 (Logic In1) or Option 24

(Logic In2).
