SP and time comprise the settings for a single segment in a pattern. Up to 30 segments can be linked to create a broken-line whose vertical axis is SP and horizontal axis is time. This system is called the “RAMP-X” system.

SP setting: Within range of SP limitter upper and lower limits

Timesetting: 0 to 99h, 59min or 0 to 99min, 59s (Select the time unit in setup data C 6 4.)

SP is the point that corresponds to the time elapsed in the current segment on a straight line made by jointing the start point (SP setting value of the previous segment) to an end point (SP setting value of the current segment).

Accordingly, segments are categorized as follows:

•Rising ramp (rising ramp, rising tendency)

Previous segment SP setting value < current segment SP setting value

•Falling ramp (falling ramp, falling tendency)

Previous segment SP setting value > current segment SP setting value

•Soak (soak)

Previous segment SP setting value = current segment SP setting value

In the case of the No.1 segment, both the start and end points become the soak segment of the No.1 segment SP setting values.

SP (other than No.1 segment) is calculated as by the following formula:

SP = (current segment SP setting value - previous segment SP setting value) x (current segment elapsed time ⎟ current segment time setting) + previous segment SP set- ting

Time setting of current segment

SP setting value of previous segment

SP setting value of current segment
