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 Digital Inx Sel parameters (A051-A054) to

option 23 “Logic In1” or option 24 “Logic In2”.

Example

• Run at Step 0.

• Transition to Step 1 when Logic In1 is true.

Logic senses the edge of Logic In1 when it transitions from off

to on. Logic In1 is not required to remain “on”.

• Transition to Step 2 when both Logic In1 and Logic In2 are true.

The drive senses the level of both Logic In1 and Logic In2 and

transitions to Step 2 when both are on.

• Transition to Step 3 when Logic In2 returns to a false or off

state. Inputs are not required to remain in the “on” condition

except under the logic conditions used for the transition from

Step 2 to Step 3.
