You desire an auto tune calculation independently 
from the starting conditions (e.g. Set Point change 
during tune execution, etc).

Note: 

Fast auto-tune can start only when the measured 
value (PV) is lower than (SP + 1/2SP).

Available: 

When [57] cont = PID.

Range: 

-4... 8 where:

-4

  Oscillating auto-tune with automatic restart at 

all Set Point change;

-3

  Oscillating auto-tune with manual start;

-2

  Oscillating auto-tune with automatic start at the 

first Power ON only;

-1

  Oscillating auto-tune with automatic restart at 

every Power ON;

0

  Not used;

1

  Fast auto tuning with automatic restart at every 

Power ON;

2

Power ON only;

3

  FAST auto-tune with manual start;

4

  FAST auto-tune with automatic restart at all Set 

Point change.

  EvoTune with automatic restart at every Power 

ON;

6

  EvoTune with automatic start at the first Power 

ON only;

change.

Note: 

All auto-tunes are inhibited during program execution.

[59] Aut.r - Manual start of the auto-tune

Available: 

When [57] cont = PID.

Range: oFF

[60] HSEt - Hysteresis of the ON/OFF control

Available: 

When [57] cont is different from PID.

Range: 0... 9999

 engineering units.

[61] cPdt - Time for compressor protection

 seconds.

[62] Pb - Proportional band

Available: 

When [57] cont = PID.

Range: 1... 9999

 engineering units.

Note: 

Auto-tune functions calculate this value.

[63] ti - Integral time

Available: 

When [57] cont = PID.

Range: OFF

 

Integral action excluded;

1... 9999

 seconds;

inF

 

Integral action excluded.

Note: 

Auto-tune functions calculate this value.

Range: oFF

 

Derivative action excluded;

1... 9999

 seconds.

Note: 

Auto-tune functions calculate this value.

[65] Fuoc - Fuzzy overshoot control

This parameter reduces the overshoot usually present at 
instrument start up or after a Set Point change and it will be 
active only in this two cases.

Setting a value between 0.00 and 1.00 it is possible to slow 
down the instrument action during Set Point approach.
Setting 

Fuoc = 1

 this function is disabled.

Available: 

When [57] cont = PID.

Range: 0... 2.00

.

Note: 

Fast auto-tune calculates the Fuoc parameter while 
the oscillating one sets it equal to 0.5.

[66] tcH - Cycle time of the heating output

Available: 

When at least one output is programmed in order 
to be the heating output (H.rEG) and  
[57] cont = PID.

Range: 2... 130.0

 seconds.

[67] rcG  - Power ratio between heating and  

cooling action (relative cooling gain)

The instrument uses the same PID parameter set for heat 
and for cool action but the efficiency of the two actions are 
usually different.
This parameter allows to define the ratio between the efficiency 
of the heating system and the efficiency of the cooling one.
An example will help us to explain you the philosophy.
Consider one loop of a plastic extruder.  The working 
temperature is equal to 250°C.
When you want to increase the temperature from 250 
to 270°C (

D

T = 20°C) using 100% of the heating power 

(resistor), you will need 60 seconds.
On the contrary, when you want to decrease the temperature 
from 250 to 230°C (

D

T = 20°C) using 100% of the cooling 

power (fan), you will need 20 seconds only.
In our example the ratio is equal to 60/20 = 3 ([67] rcG = 3) 
and it say that the efficiency of the cooling system is 3 time 
more efficient of the heating one.

Available: 

When two control action are programmed  
(H.rEG and c.rEG) and [57] cont = PID.

Range: 0.01... 99.99

.

Note: 

Auto-tune functions calculate this value.

[68] tcc - Cycle time of the cooling output

Available: 

When at least one output is programmed in order 
to be the cooling output (c.rEG). 

Range: 2... 130.0

 seconds.

[69] rS - Manual reset (integral pre-load)

It allows to drastically reduce the undershoot due to a 
hot restart.  When your process is steady, the instrument 
operates with a steady power output (e.g.: 30%).
If a short power down occurs, the process restarts with a 
process variable close to the Set Point while the instrument 
starts with an integral action equal to zero. 
Setting a manual reset equal to the average power output (in our 
example 30%) the instrument will start with a power output equal 
to the value it will use at steady state (instead of zero) and the 
undershoot will become very little (in theory equal to zero).

Available: 

When [57] cont = PID.

Range: -100.0... +100.0%
