This function is effective when the motor shaft has stopped and is not
to
be rotated, or when preheating
the motor.
When

ldb[
I setting value after normal DB operation. This condition can be maintained as long as ST-CC
is
not
opened, emergency stop is not engaged, or the power is not turned
OFF. To stop this function, disengage
the operating command by one of the methods previously mentioned, and DB
will stop.
