Adjustment Level Section 5-4
• This parameter sets the rate of change during SP ramp operation. Set the
maximum permissible change width per unit of time as the SP ramp set
value. The SP ramp function is disabled if this parameter is set to OFF.
• During temperature input, the decimal point position of the SP ramp set
value is dependent on the currently selected sensor, and during analog
input it is dependent on scaling.
• The set value is saved in the SP Ramp Set Value parameter for the cur-
rent bank.

• The MV Upper Limit and MV Lower Limit parameters set the upper and
lower limits of the manipulated variable. When the calculated manipulated
variable exceeds the upper or lower limit value, the upper or lower limit
value will be the output level.
• The set value is saved in the MV Upper Limit and MV Lower Limit param-
eters for the current PID set.

The setting ranges during standard control, heating/cooling control, and
position-proportional (close) control are different.
