Keyboard Operation

The parameter set can only be changed by a programmable parameter. After the
blinking dot is brought behind the display of the parameter set with ENTER, then the
desired set can be adjusted with UP/DOWN. This is not necessarily the set in which
the inverter presently operates, but rather the set of the parameter selected which
should be displayed or changed.
In addition to sets 0-3 the value A (active) can also be set. During this setting the value
is always shown which is being adjusted in the set presently active. The adjusted
parameter value cannot be changed in this setting.
4.1.2 Display of the Parameter Value
By pressing UP or DOWN the value of the adjusted parameter can be changed in the
parameter value display. These changes are effective immediately and permanently
stored, meaning they are still valid after the unit is switched off. ENTER does not need
to be pressed to confirm the input.
For some parameters it is not useful, that the value set by UP/DOWN immediately be
valid. When for example, during digital rotation setting you want to change from LS to
REV, then FOR may not immediately be activated when UP is pressed. These
parameters are called Enter parameters, because they must be verified by ENTER.
Only the display is changed when pressing UP /DOWN and not the value stored in the
inverter. When the display value and the stored value in the inverter are different, this
is characterized by a point in the display. The display value in the inverter is stored and
the dot is no longer visible when ENTER is pressed. The parameter value display of an
Enter parameter always begins with the value stored in the inverter. A list of all Enter
parameters is found in the supplement.
4.1.3 Special Displays
When a malfunction occurs in the inverter the display is overwritten by an error
message. This error message blinks. By pressing ENTER the display of the error
message is interrupted and the parameter value of the last parameter adjusted is
shown. No error reset occurs when ENTER is pressed, meaning the error status in the
inverter is not reset. As a result it is possible to correct adjustments before an error
reset. An error reset is only possible with the terminal control release or reset.
Some inputs, e.g. copying a set, are acknowledged with a message from the inverter.
