3.4. KEYPAD
3.4.1. DESCRIPTION OF KEYBOARD OPERATION
The keyboard has three keys: '
S
' (selection), '
+
' (increase) and '
-
' (decrease), and it has a display with four
and a half digits plus the decimal points and the minus sign '-'.
3.4.2. IDLE STATE
When the equipment is switched on, the keyboard displays "
Stop
"; if there are any alarms, the keyboard
flashes, displaying "
Stop
" intermittently. When the drive is working, if no special magnitude to be displayed
has been set (see '
c13
'), magnitude
d5
is displayed. The keyboard automatically returns to the rest state ten
seconds after the last operation, expecting that it doesn,t display an internal quantity or a digital state.
3.4.3. SETTING AND READING OF PARAMETERS AND CONNECTIONS
Press push-button '
S
' and the keyboard will display the last parameter or magnitude selected, then, by using
the '+' and ' -' keys, scroll the menu up and down until you find the address of the parameter (
P
) or of the
connection (
c
) to be read and, if necessary, corrected. Next to the number of the parameter or connection
the letter '
r
' appears if the parameter is reserved, '
t'
if it is TDE-reserved and '
n
' if it is a parameter that can
be modified only when the drive is not running; all the reserved parameters are '
n
'-type parameters which
may be modified only when the drive is not running (off-line).
On pressing key '
S
', the parameter value is displayed and can therefore be read; press '
S
' again to go back
to the menu and the system also automatically goes back to the menu 10 seconds after the beginning of the
display; to correct the parameter or connection value, when this is displayed, press the '-' and '+' keys at the
same time; the decimal point of the first figure at the left then starts to flash, which means that, from that
moment on, pressing the '-' and '+' keys changes the value set. The value is changed only from stop if the
parameter is OFFLINE or only after the access code,
P50
, has been set, if the parameter is reserved, or
P80
for TDE-reserved parameters.
The TDE-reserved parameters and connections are not listed, unless access code
P80
is set.
Once the value has been corrected, press '
S
' to go back to the menu confirming the modified parameter or
connection; to exit without confirming, just wait for ten seconds and then the keyboard will display the
address discarding the changed value; if the value is not touched, just press '
S
' to exit (the previous value
will be confirmed). Once in the menu, the keyboard automatically returns to the rest state.
3.4.4. DISPLAY OF INTERNAL MAGNITUDES
Move from the menu with the '
+
' or '
-
' keys until the address of the magnitude to be displayed '
dxx
' appears;
on pressing '
S
' the address disappears and the value is displayed.
Return to the menu from this state by just pressing '
S
'; returning from the menu to the rest state is automatic
after 10 seconds.
3.4.5. DISPLAY OF I/O AND ALARMS
From the menu use the '+' and '-' keys to move to the address required for the digital inputs (
i
), the outputs
(
o
) and the alarms (
A
); the box to the right shows this and the state: 'H' = active (high), 'L' = not active (low).
To return to the rest state from this state, just press '
S
'.
ATTENTION:
For the complete list of all the magnitudes given by the keypad, refer to the chapter 9 on the
user manual.
