Programming 6–61
StepLogic™ offers a degree of PLC functionality for simple applica-
tions. It consists of 7 frequency steps which can be stepped through
based on a number of factors. The frequency steps are programmed
into the [Preset Freq x] parameters (x = Current Step + 1). Each step
also has a time associated with it, [SLx Time]. The logic for each step
is defined by four StepLogic parameters.
• [SLx Logic Step] – if true, will move the program to the next step.
• [SLx Logic Jump] – if true, will jump to the step defined in [SL
Step Jump].
• [SL Step Jump] – if both [SLx Logic Step] and [SLx Logic Jump]
are true, the program will jump to the step defined in this parame-
ter. [SLx Logic Jump] takes precedence over [SLx Logic Step].
• [SLx Step Setting] – sets 4 functions of the step. Refer to the
parameter description on page 6–63 .
A valid Start command will cause the program to run and continue to
loop unless one of the steps causes the program to end, a Stop com-
mand is given or the Enable is opened. When the Enable is opened in
2-wire control, the drive will stop. When closed, the drive will restart
at the last step, if the Start is still closed. Note that in order to move to
a different step based on digital inputs, at least one input must change
state since the last step.
See Example below and Figure 6.1 .
