4.2.3 Slope setting
The slope is a function related to SV (set value) that prevents the rate of SV from
being limited due to a sudden change (increase or decrease) in the temperature of the
controlled object.

Slope state in different modes
For ceramic or ceramic furnaces, heating too fast may
damage the porcelain in the ceramic furnace, and the
slope heating function can achieve slow heating.
When SV (set value) is operated based on the slope setting value based on PV (display value)
and the value of SV or slope is changed, the SV operation amount changes according to the
corresponding change amount.
Determine the SV control object and set the corresponding slope according to the SV variation.
(hereinafter referred to as RAMP SV)
The amount of change in the rise and fall of the slope can be set separately.
The alarm output and slope depend on the SV value.
This function can't be used when the slope is set to 0.
