The current required by the speed controller is limited to the current limit.

Positioning window - Position reached
Position reached indicates that the target position is located within the position
window.
In addition to the position window, a position window time is supported. If the actual
position goes inside the position window, the position window time is started. If the
actual position is still inside the position window after the position window time,
"Position reached" is set.
If the actual position leaves the position window within the position window time,
the position window time is started again.
When the actual position leaves the position window with Position reached = "1",
Position reached is immediately reset to "0".
Position monitoring is active even if the position leaves the position window
because of measures taken externally.

Linkage to the setpoint value
The signal “position reached” can be linked to the setpoint value.
In addition, the internal setpoint value generation is evaluated.
It applies:
The positioning window is only evaluated with a constant internal
setpoint value.
Signal “position reached” monitors synchronicity.
Signal §position reached” is set if
RegSearch was terminated without a reg being found
or
Reg was found and RegMove executed.
