Check output voltage

S

0 ... 3
{ 0 }
This protective function monitors the output current at the U-V-W terminals and checks for
plausibility. In cases of error, the error message E016 is output.
0 = Switched off:
Monitoring is not active.
1 = Motor Phases only:
The output current is measured and checked for symmetry. If an
imbalance is present, the VFD switches off and outputs the error message E016.
2 = Magnetisation only:
At the moment the VFD is switched on, the level of the excitation
current (field current) is checked. If insufficient excitation current is present, the VFD
switches off with the error message E016. A motor brake is not released in this phase.
3 = Motor Phase + Magnet:
Monitoring of the motor phases and magnetization as in 1 and 2
are combined.
NOTE:
This function can be used as an additional protective function for lifting applications,
but is not permissible on its own as protection for persons.

0 ... 7
{ 0 }
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 = No limitation,
"No restriction of direction of rotation"
1 = Disable phaseseq. key,
rotation direction change key
of the Simple Box is locked
2 = To the right 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 = To the left only*
, only counterclockwise 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 = Right Orient. Contr.
, “Only clockwise monitored"
*, only clockwise rotation is possible.
The selection of the "incorrect" rotation direction leads to the VFD switching off (control
block). If necessary, an adequately large setpoint value (>fmin) must be observed.
6 = Left Orient. Contr.
,
"Only counterclockwise monitored"
*, only counterclockwise rotation
is possible. The selection of the "incorrect" rotation direction leads to the VFD switching
off (control block). If necessary, an adequately large setpoint value (>fmin) must be
observed.
7 = Enable Direct. Contr. only,
"Only enabled direction monitored
, Rotation direction is only
possible according to the enable signal, otherwise the VFD is switched off.
*) Applies for control via keyboard and control terminals.
