SHORTSIZ16 e1432_set_rpm_low(E1432ID hw, SHORTSIZ16 ID,
                             FLOATSIZ32 rpm)
SHORTSIZ16 e1432_get_rpm_low(E1432ID hw, SHORTSIZ16 ID,

.SH DESCRIPTION
\fIe1432_set_rpm_low\fR sets the lower limit of arming RPMs used by the RPM
arming modes of the \fIe1432_set_arm_mode\fR function.  The value entered
is a floating point number, but it is truncated to a integer internally;
so the value returned by \fIe1432_get_rpm_low\fR will always be an
integer represented as a floating point number.

\fIe1432_get_rpm_low\fR returns the lower limit RPM into 
the variable pointed to by \fIrpm\fR.

\fIhw\fR must be the result of a successful call to
\fIe1432_assign_channel_numbers\fR, and specifies the group of
hardware to talk to.

\fIID\fR is either the ID of a group of channels that was obtained
with a call to \fIe1432_create_channel_group\fR, or the ID of a single
channel.

\fIrpm\fR specifies the lower limit RPM.

\fBNOTE:\fR  When in the order tracking measurement, the following relationship
between these parameters must be observed:

	rpm_low >= (60 * span) / (64 * max_order)

or a WARN1432_LOST_RPM_TOO_LOW warning will be issued and an arming point lost.

Arming begins at this threshold on a runup measurment or ends at this
threshold on a rundown measurement.  
.SH "RESET VALUE"
After a reset, \fIrpm\fR is set to 600.0.
.SH "RETURN VALUE"
Return 0 if successful, a (negative) error number otherwise.
