Master
The device is designated as
the master.

Follower
The device is designated as
the follower.
Auto. tap sync.
Automatic assignment of
master or follower.
If a master is not detected,
the device with the lowest
CAN bus address is auto-
matically designated as the
master. All other devices are
designated as followers.

9.3.3.2.3 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.
9.3.3.2.4 Setting circulating reactive current sensitivity
You can use this parameter to set the influence of circulating reactive current
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.
9.3.3.2.5 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 is based on the rated current of
the current transformer. If, during parallel operation, the circulating reactive
current exceeds the set limit value, the device triggers the
Circulating reac-
tive current blocking limit exceeded
event. All devices operating in the paral-
lel operation group are blocked.
