4.1.4 ENTER-Parameter
For some parameters it is not sensible that the selected values become active immediately. For that reason
they are called ENTER-Parameters, they do not become active until the ENTER key is pressed.
Example: At digital setting of rotation direction the rotation reverse (r) shall be selected from standstill (LS).
As seen above it must be switched at this in forward direction of rotation (F). The drive shall start only if the
direction of rotation reverse is selected and confirmed with ENTER.
4.1.5 Non-programmable parameters
Certain parameters are not programmable, as their value must be the same in all sets (e.g. bus address or
baud rate). For an easy identification of these parameters the parameter set number is missing in the para
-
meter identification.
For all non-programmable parameters the same value is valid independent of the
selected parameter set!
4.1.6 Resetting of error messages
If a malfunction occurs during operation, the actual display is overwritten by a by a blinking error message. The
error message can be deleted by pressing the ENTER key, so the initial value is displayed again.
ATTENTION! The resetting of the error message with ENTER is no error reset, i.e. the error status in the in-
verter is not reset. Thus is possible to correct adjustments before the error reset. An error reset is only possible
by the reset terminal or control release.
4.1.7 Resetting of peak values
To permit conclusions on the operational performance of the drive, parameters are provided that indicate the
peak values. Peak value means that the highest measured value is stored for the ON-time of the inverter
(slave pointer principle). The peak value is cancelled by ▲ or ▼ and the actual measured value is displayed
.
4.1.8 Acknowledgement of status signals
To monitor the correct execution of an action some parameters send a status signal. For example, "PASS"
is displayed after copying a set to indicate that the function was completed error-free. These status signals
must be acknowledged with ENTER.
