mV-e
MV at PV Error
The control must be set to 2-PID control or a
Position-proportional Model must be used.
The MV at Stop and Error Addition parameter must
be ON.
• This parameter sets the MV to use when an input error occurs.

sprt
SP Ramp Set Value
The ST (self-tuning) parameter must be set to OFF
(default: ON).
sprl
SP Ramp Fall Value
• These parameters set the rate of change during SP ramp operation. They set the
maximum permissible change width per unit of time as the SP ramp set value and the SP
ramp fall value. The SP ramp function is disabled if this parameter is set to OFF.
• For a temperature input, the decimal point positions of the SP ramp set value and SP
ramp fall value depend on the currently selected sensor, and for an analog input they
depend on the Decimal Point parameter.
