Retry torque block parameter
In case of block outside the end position range, the actuator repeatedly moves against the block
(1 to 5 times).

End position range parameter
= End position range in end position
CLOSED.
= End position range in end position OPEN.
Possible setting: in 1 % steps:
■
End position range CLOSED
from [0 % to 2 %] to [0 % to 20 %]
■
End position range OPEN
from [98 % to 100 %] to [80 % to 100 %]
Within the end position range, travel is at a low
speed (or long positioning time). If the actuator
trips torque-dependently outside this range, it is
recognized as a fault ("Blocked in move“, refer to
chapter „4.3 Actuator status indication“ on page
18.
End position range
98 – 100 %
0 – 2 %

If the "Retry torque block“ parameter value is
equal to 0, this means that the position does not
have to be approached again.
If the parameter value is not equal to zero, the
actuator is automatically operated in the oppo-
site direction (for a travel which corresponds to
the end position range, but not longer than 2 s)
and the back in direction of the block.
This happens until the block has been overcome
or the programmed number of tries has been
reached.
If the block is not overcome, the actuator is
tripped and the "Blocked in move" fault signal
is set. The actuator continues to signal "ready"
since it can still be operated into the opposite
direction.
Default setting is 0.
