Function Effects
Status display
The LCD (five-digit display for BOP, multi-line clear-text display for AOP) shows the settings
used presently by the VSD or used to parameterize the VSD).
Start motor
Pressing this button starts the variable speed drive. This button is enabled for manual mode as
part of the factory setting.
Stop motor
OFF1 Pressing this button stops the variable speed drive within the selected ramp-down time.
This button is enabled for manual mode as part of the factory setting.
OFF2 Pressing this button twice (or once with sustained pressure) causes the motor to coast
freely to a standstill. This function is enabled in the manual and automatic operating
modes.
Changeover to
manual control
Pressing this button while the VSD is running sets the input logic so that the operator controls
the SED2. In this mode, none of the controlled variables have any influence on the control of
the VSD.
Changeover to
automatic
control
In automatic mode, all I/Os are set to represent the system-dependent variables. No manual
inputs are accepted.
The controller responds to changes depending on its parameter setting.
However, it is possible to change system parameters in automatic mode.
Functions
This button allows for displaying additional information. Refer also to the section Buttons with
special functions in the AOP operating instructions.
Multiple display mode
When you press this button for 2 seconds during operation, the following information is
displayed regardless of the parameter:
1. DC link voltage (indicated by d – units V).
2. Output current (A).
3. Output frequency (Hz).
4. Output voltage (indicated by o – units V).
5. The value selected in P0005. (If P0005 is configured to display any of the above (1 to 4),
the value is not redisplayed).
Briefly press the key repeatedly to cycle through the above displays. Pressing again this button
for a sustained time exits the multiple display mode.
Jump function
You can jump from any parameter (rXXXX or PXXXX) directly to r0000 by pressing the Fn
button briefly. This allows you to modify another parameter if required. After jumping to r0000,
press the Fn button again to return to the starting point.
AOP only
Pressing buttons Fn and P simultaneously opens the main menu.
Access to
parameters
Pressing this button allows you to: 1. Access the parameters, and 2.: Exit the parameter by
accepting its value.
Increase value
Press this button to increase the value displayed. This button helps increase the current value
during parameterization.
In manual mode, this button allows for increasing the speed (internal motor potentiometer).
Decrease value
Press this button to decrease the value displayed. This button helps decrease the current
value during parameterization.
In manual mode, this button allows for decreasing the speed (internal motor potentiometer).
