ED
manner as the parallel operation method for circulating reactive current mini-
mization, and provides you with the safety function of circulating reactive
current blocking. The Circulating reactive current blocking parameter is used
to set the limit value.
Master/follower switching characteristics
You can use this parameter to set the switching characteristics for the tap
synchronization parallel operation method.. You can select the following op-
tions:
▪ Sequentially: When a tap-change operation takes place, the master com-
municates its new tap position to the followers via the CAN bus as soon
as the master has completed its tap-change operation. The tap-change
operations of the master and followers thereby take place one after an-
other (sequentially).
▪ In sync: When a tap-change operation takes place, the master communi-
cates its new tap position to the followers via the CAN bus as the master
starts its tap-change operation. The tap-change operations of the master
and followers thereby take place at almost the same time (in synch).
Maximum tap difference
You can use this parameter to set the maximum permissible tap difference
between followers and master on the follower.
If the tap difference is greater than the set maximum tap difference to the
master, the follower blocks and no longer attempts to attain the master's tap
position. After the set delay time for parallel operation error messages has
elapsed, the follower issues the Permitted tap difference to master exceeded
message.
Error if no communication present
You can use this parameter to set whether it is an error if the device does
not receive any messages via the CAN bus or if there are no other CAN bus
participants in the same parallel operation group.
Behavior if no communication present
You can use this parameter to set how the voltage regulator behaves if com-
munication via the CAN bus is not possible.
The setting for this parameter is only effective if you have selected the Error
option for the Error if no communication present parameter.
