For safety reasons this parameter can be used to prevent a rotation direction reversal and
therefore the incorrect rotation direction.
This function does not operate with active position control (P600 ≠ 0).
0 =
None, "No restriction of direction of rotation"
1 =
Dir key locked, rotation direction change key
of the SimpleBox is locked
2 =
Clockwise only*, only clockwise direction is possible. The selection of the "incorrect"
rotation direction leads to the output of the minimum frequency P104 with the field of
rotation R.
3 =
Anticlockwise only*, only counter-clockwise direction is possible. The selection of the
"incorrect" rotation direction leads to the output of the minimum frequency P104 with the
field of rotation L.
4 =
Enable direction only, rotation direction is only possible according to the enable signal,
otherwise 0Hz.
5 =
Clockwise only monitored
, "Only clockwise monitored*, only clockwise rotation is
possible. The selection of the "incorrect" rotation direction leads to the FI switching off
(control block). If necessary, a sufficiently large setpoint value (>f
min
) must be observed.
6 =
Only anticlockwise monitored
, "Only anticlockwise monitored" *, only anticlockwise
rotation is possible. The selection of the "incorrect" rotation direction leads to the FI
switching off (control block). If necessary, an adequately large setpoint value (>f
min
) must
be observed.
7 =
Only enable monitored, "Only enabled direction monitored, Rotation direction is only
possible according to the enable signal, otherwise the FI is switched off.
*) Applies for control via keyboard and control terminals.
