The IOP has a navigation wheel and five further keys. The associated functions are shown in
the table below.
Table 5- 1 Functions of the IOP keys
Key Function
The navigation wheel has the following functions:
• In a menu, turning the key changes the selection.
•
If a selection is marked, pressing the key confirms the selection.
• When a parameter is changed, turning the key changes the displayed value. Turning clockwise increases
the value; turning counterclockwise decreases the value.
•
When parameters or search values are changed, it is possible to change individual digits or the complete
value. Pressing the navigation wheel for a longer time (> 3 seconds) switches between the two different
change modes.
The ON key has the following functions:
• In the AUTO mode, the display shows an information screen which shows that the command source is
AUTO and that it can be changed by pressing the MANUAL/AUTO key.
•
In the MANUAL mode, the inverter is started. The symbol for the inverter state begins to turn.
MANUAL mode can be selected during active AUTO mode. The motor continues to run with the most recently
selected speed setpoint.
If the inverter runs in MANUAL mode, the motor stops when a switch is made to AUTO mode.
The OFF key has the following functions:
•
If the key is pressed for longer than 3 seconds, the inverter performs the OFF2 command and the motor
coasts down to standstill.
Comment: If the OFF key is pressed twice within 3 seconds, the inverter also performs the OFF2 com-
mand.
•
If the key is pressed for less than 3 seconds, the following actions are performed:
–
In the AUTO mode, the display shows an information screen which shows that the command source is
AUTO and that it can be changed by pressing the MANUAL/AUTO key. The inverter is not stopped.
– In the MANUAL mode, the inverter performs an OFF1 command and the motor comes to standstill in
the ramp-down time set in parameter p1121.
The ESC key has the following functions:
•
If the key is pressed for less than 3 seconds, the IOP returns to the previous screen or, if a value was
changed, the new value will not be saved.
• If the key is pressed for longer than 3 seconds, the IOP returns to the Status screen.
If the ESC key is pressed in Parameter change mode, the data will be saved only when the OK key is
pressed.
