Description
Dim.
Feedback
PC
[437]
Feedback value of the process controller. If the process controller is turned on and
works correctly, the value is near the value Setpoint value [39] (page 67).
Error PC [438]
Regulation error of the process controller. In steady-state, it should be close to 0.
Output PC [439]
Action value (output) of the process controller.
State PC [789]
Actual state of the process controller.
□
Lower
saturation
Process controller operates at lower saturation.
□
Upper
saturation
Process controller operates at upper saturation.
□ Error in the
dead-zone
Process controller error in the dead-zone.
□ Positive error Process controller error is positive.
□ SP achieved
If error is lower than hysteresis.
□ Parked
Process controller is parked.
□ PC Reset
Active PC RESET - integration term and the output are equal to the value PC Reset value
[977] (page 68).
4.6.3 Optimization
Group of parameters number [648]
Setting the parameters for the optimization block that is used to search for the extremum of any signal using
the change of a selected entering setpoint signal.
Optimization searches for an output value, at which it reaches the criteria of the selected signal. During the
optimization, if the measurement conditions and the operation condition are met, new output samples are
counted in defined intervals. The found global extremum is stored to the memory. In case the optimization
output should apply, it is necessary to select its output as the source of the setpoint value.

Description
Dim.
OPT
Output
[434]
Output value of the optimization block. You can watch the status and quality of the
optimization process here. 100% represents the min.-max. range from the setpoint
channel, which is connected to the optimization block (see [24] (page 69)).
Optimization
step [666]
Optimization step represents the difference between two consecutive optimization
algorithm samples. (see [24] (page 69)).
OPT
Starting
point [649]
Defines the starting point of the optimization at the optimization start, when scanning
is turned off.
OPT State [650]
Shows the present state the optimization block.
□ Reset
Optimization is in initial or blocked state.
□ Measuring
Measuring of the optimized quantity is running.
□ Scan
Scanning of the whole optimization output range is running.
□ Tuning
State of fine tuning and searching for the optimization point.
4.6.4 Ext. thermal protection
Group of parameters number [803]
Diagnostic group of quantities of the external thermal protection (ETP).
MENU \ DIAGNOSTICS \ FUNCTIONS \ EXT. THERMAL PROTECTION
Name [ID]
Description
Dim.
ETP
Temperature
[799]
Temperature of the ETP sensor. After exceeding the temperature defined in the
parameter ETP Warning [796] (page 71), the inverter generates a warning. After
exceeding the temperature defined in the parameter ETP Fault [797] (page 71), the
inverter generates the fault " E38-ETP temperature (page 33)".
°C
ETP
Current
[800]
Measuring current of the external thermal protection. By rule, it is selected as the
signal source of an analog input, AOUT1 to AOUT3.
mA
ETP
Voltage
[798]
Value of measured voltage drop on the ETP sensor.
V
Sensor
resistance
Resistance value of the ETP sensor.
By multiple sensors connected to a series, it represents the average resistance value
Ω
