channel. Optimization has its own output, which operates in the interval 0.000 to 1.000 and it is
possible to display it in the converter diagnostics:
Parameter ID: 423
DIAGNOSTICS
– > Functions -> Optimization -> OPT Output [ ]
The optimization output connection to any entering channel is performed after selecting this
parameter by selecting the signal (source) of the corresponding entering channel.
Value selection, which criteria should be searched by the optimization block is performed by
parameter configuration:
Parameter ID: 80
SETTINGS
– > FUNCTIONS -> OPTIMIZATION -> Optimization signal
Motor current, motor power and motor torque are selected as the
optimization signal in standard optimization tasks mostly. After
selecting one of the analog inputs, it is possible to optimize any
technological value.
Optimization criteria defines, if converter will search for the minimum or the maximum of the
selected signal. For example on generator drive of hydro power-plant, if we want to maximize the
produced power and minimalize the power losses on a pump drive.
To select the criteria, use the parameter:
Parameter ID: 208
SETTINGS
– > FUNCTIONS -> OPTIMIZATION -> Optimization criteria
Blocking (reset) the optimization and measurement condition:
Two signals are in the OPTIMIZATION block, that control the optimization operation conditions and
a condition, when it is possible to measure optimized values.
To configure the conditions for blocking and reseting the optimization, use the signal:
Parameter ID: 263
SETTINGS
– > FUNCTIONS -> OPTIMIZATION -> Opt. Reset signal
For example: If the optimization is set to search for maximal or
minimal power, it is necessary to block its operation when the
device is turned off. Then the parameter „Opt. reset signal“ [263] is
set to the value Converter status negated (negation of the status
word) and the command Run (converter generates the output
voltage) is set in the parameter „Opt. Reset“ [273] concurrently.
Since the status word is negated , it means that, optimization
Reset is active when the converter does not generate the output
voltage.
