8.9.2.3 Assigning a CAN bus address
You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. If the value is set to 0, then no communication takes place.
1. Go to Settings > Parameters > Parallel operation > CAN bus address .
2. Enter CAN bus address.
3. Press the Accept button to save the modified parameter.
8.9.2.4 Setting circulating reactive current sensitivity
You can use this parameter to set the influence of circulating reactive cur-
rent on how the control deviation is calculated. The higher the set value, the
greater the calculated control deviation as a result of circulating reactive cur-
rent.
To determine the ideal circulating reactive current sensitivity, note the rele-
vant section in the Commissioning chapter.
To set the circulating reactive current sensitivity, proceed as follows:
1. Go to Settings > Parameters > Parallel operation >Circulating reac-
tive current sensitivity .
2. Enter the circulating reactive current sensitivity.
3. Press the Accept button to save the modified parameter.
8.9.2.5 Setting the circulating reactive current blocking limit
You can use this parameter to set the limit value for the maximum permissi-
ble circulating reactive current. This value relates to the rated current of the
current transformer. If, during parallel operation, the circulating reactive cur-
rent exceeds the set limit value, the device triggers the
Circulating reactive
current blocking limit exceeded event. All devices operating in the parallel
operation group are blocked.
To set the circulating reactive current blocking limit, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Circulating reac-
tive current blocking limit .
2. Enter the circulating reactive current blocking limit.
3. Press the Accept button to save the modified parameter.
8.9.2.6 Setting desired power factor
You can use this parameter to set the power factor, which the transformer
has under normal operating conditions. If the measured power factor devi-
ates from the desired one, the device calculates a correction which is added
to the control deviation.
