• If the initial value is 0.0, the SP ramp does not operate. Therefore, by setting the
up slope to greater than 0.0 and setting the down slope to 0.0, the SP ramp can
be set to function only when the SP is increasing, not when the SP is decreasing.
This setting can be reversed so that the SP ramp functions when the SP is
decreasing but not when the SP is increasing.
• Under the following conditions, if the SP ramp is set to enable both up and down
slopes, the ramp starts with the current SP as the starting point.
