This parameter affects the temperature sequence only in
case of internal control.
Factory setting: APER (aperiodic)
Possible parameters:
NORM Allows for reaching the setpoint faster – with
setpoint change or ramp function – but
overshooting of up to 5 % is possible.
APER Ramp function: the increase of temperature
occurs temporally offset and achieves the
target temperature without overshooting.
Setpoint change: The temperature increases at
the same rate, the target temperature is
achieved without overshooting.

With both settings constant temperature is achieved
after approximately the same time.
9.5.3. Control parameters – XPU-, XP-, TN-, TV- EXTERNAL
Setting range: 0.1 ...99.9
Setting range: 3 ...9999
Setting range: 0 ... 999
In most cases the control parameters preset in the factors are adequate
for achieving an optimum temperature sequence.
The control parameters allow adjustment to special control processes.
Setting range: 0.1 ... 99.9
Proportional range >Xpu<
The proportional range Xpu of the cascaded controller is only needed for
external control.
