Discrete Input
The MCA board has a single discrete input which can be programmed for
use in the Drive. Figure 3–2 shows this input and the parameters that
control its use.

ATTENTION: The Start/Stop circuitry in this drive is
composed of solid-state components. If hazards due to
accidental contact with moving machine components or
unintentional flow of liquid, gas or solids exist, NEMA
standards require that a hardwired maintained contingency Stop
circuit such as the one shown at terminals 1–2 of J5 be used
with this Drive.
