Limit Output Enabling
Every output can be conditioned to fire based on:
the present Global Machine Speed value (
Speed Enabling
)
the present state of an input. (
Simple ANDing
)
whether or not the input has been active within the programmed setpoint pair. (P
ulse ANDing
)
whether or not the input was active within an associated, and programmable,
Enabling Window.
(Window ANDing)
the state of a bit in the Shift Register of the ANS1. (
Shift Register ANDing
)
Also:
Each output can have none, or one or more inputs associated with it.
ANDing types can be mixed on an output. For example, an output can have Simple ANDing with input
1 and Windowing ANDing with input 5.
Each input can have multiple outputs associated with it.
Machine Speed Enabling
Each output can have a speed based limit switch associated with it. The limit switch is programmed with an
RPM Enable High Setpoint
and an
RPM Enable Low Setpoint
.
When the RPM Enable Low Setpoint is
less than
the RPM Enable High Limit, the associated output is
enabled when the Global Machine Speed is between the two limit values.
When the RPM Enable Low Setpoint is
greater than
the RPM Enable High Limit, the associated output
is enabled when the Global Machine Speed is outside of the two limit values.
Simple ANDing
The physical output is only on when the associated physical input is active and the position is within the pro-
grammed setpoints.
