Example 1:
The positive sequence components of the currents are to be output as analog output B1 at location "B". 10 mA
is to be the value at nominal operational current, consequently 20 mA corresponds to 200 %. Values below 1
mA are invalid.
Settings:
Address 7301 20 mA (B1/1) = 200.0 %,
Address 7302 MIN VALUE(B1/1) = 1.0 mA.
Measured Values for Analog Outputs of Type 2
This analog output type enables the measured values to be output universally. The value range of the mea-
sured values and the current of the analog interface to be output can be selected in a large range.
In the addresses 200, 201, 202 and 203 you can define which of the analog outputs (B1, B2, D1 and D2) are
used for which measured value.
If you have selected measured values for the analog outputs, you should make the following settings:
• for analog output 1 at location "B" (port B1):
Address 7310 MIN. VALUE B1/2 the minimal reference value in %.
Address 7311 MIN.OUTPUT B1/2 the minimal current output value in mA,
Address 7312 MAX. VALUE B1/2 the maximum reference value in %.
Address 7313 MAX.OUTPUT B1/2 the maximum current output value in mA.
• for analog output 2 at location "B" (port B2):
Address 7320 MIN. VALUE B2/2 the minimal reference value in %.
Address 7321 MIN.OUTPUT B2/2 the minimal current output value in mA,
Address 7322 MAX. VALUE B2/2 the maximum reference value in %.
Address 7323 MAX.OUTPUT B2/2 the maximum current output value in mA.
• For analog output 3 at location "D" (port D1):
Address 7330 MIN. VALUE D1/2 the minimal reference value in %.
Address 7331 MIN.OUTPUT D1/2 the minimal current output value in mA,
Address 7332 MAX. VALUE D1/2 the maximum reference value in %.
Address 7333 MAX.OUTPUT D1/2 the maximum current output value in mA.
• For analog output 4 at location "D" (port D2):
Address 7340
MIN. VALUE D2/2 the minimal reference value in %.
Address 7341 MIN.OUTPUT D2/2 the minimal current output value in mA,
Address 7342 MAX. VALUE D2/2 the maximum reference value in %.
Address 7343 MAX.OUTPUT D2/2 the maximum current output value in mA.
The maximum current output value is determined by the setting parameter (address 73x3). It can be set to a
maximum of 22 mA. If measured values are higher than the maximum reference value, this maximum current
output value will be output. For measured values below the minimum reference value, the specified mimimum
current output value is output. The setting ranges can be selected such that both positive and negative values
can be represented over the output range, as is necessary for the display of P, Q, cos j.
The minimum reference value (address 73x0) must always be set smaller than the maximum reference value
(address 73x2) (positive increase). Otherwise 0 mA is output.
