P538 Mains voltage monitoring
S
Always available
0 ... 3
[ 3 ]
For safe operation of the FI, the voltage supply must meet a specific quality. If there is a brief
interruption of a phase or the voltage supply sinks below a particular limit value, the FI will output an
error.
Under certain operating conditions, it may be necessary to suppress this fault message. In this case,
the input monitoring can be modified.
The mains voltage monitoring must be switched off to operate the inverter on a single-phase mains
(P538 = 0).
0 = Switched off
1 = Phase failure: Only phase errors will produce an error message.
2 = Low voltage: Only low voltage will produce an error message.
3 = Phase failure and low voltage: Phase errors and undervoltage will produce an
error message.
Note: Operation with an impermissible mains voltage can destroy the frequency inverter!
P540 Rotation direction mode
S P
Always available
0 ... 7
[ 0 ] For safety reasons this parameter can be used to prevent a rotation direction reversal and therefore
the incorrect rotation direction.
0 = No rotation direction limitation
1 = Disable phase sequency key, the direction key on the ControlBox (SK TU2-CTR) is blocked.
With this parameter, the direction key in the ParameterBox is not blocked.
2 = To the right only*, only rotation right is possible. The selection of the "incorrect" rotation leads
to an enable with the minimum frequency (P104) in the "correct" direction.
Note: When using a PotentiometerBox (SK TU2-POT), function 5 is active here!
3 = To the left only*, only rotation left is possible The selection of the "incorrect" rotation leads to
an enable with the minimum frequency (P104) in the "correct" direction.
Note: When using a PotentiometerBox (SK TU2-POT), function 6 is active here!
4 = Enable direction only, rotation direction is only possible according to the enable signal,
otherwise 0Hz. With "Enable right" only positive speeds are possible, with "Enable left" only
negative speeds are possible.
Note: When using a PotentiometerBox (SK TU2-POT), function 7 is active here!
5 = Right orientation controlled *, only rotation right is possible. The selection of the "incorrect"
rotation direction leads to the FI switching off.
6 = Left orientation control *, only rotation left is possible. The selection of the "incorrect"
rotation direction leads to the FI switching off.
7 = Enable direction controlled, rotation direction is only possible according to the enable signal,
otherwise the FI is switched off.
*) Applies to keyboard (SK TU2-) and control terminal actuation, in addition, the direction key on the
ControlBox is blocked.
