Memo Parameters
Menu group to store or restore changes made to parameters.
Please note that before disconnecting the services you have to store the modified parameters otherwise they will be lost and at the next
restart there will be the previous parameters.
Save
Menu to start saving (storage) the modified parameters. Follow these points to accomplish the operation:
1. Using the buttons on the front, reach the menu “Memo Parameters → Save”.
2. In the bottom line is the words “UP to confirm”. Press the”
►" button to enter the "change parameter" mode.
3. The
“
“character
appears in the lower left
corner of the display. At this point press “▲” (i.e. UP).
4. Start the memorisation phase indicated by the words “Wait....”. At the end appears the inscription “OK” indicating that the
operation is finished correctly.
5.
At this point, you can press “◄” to confirm and exit the
“Edit Parameter
mode”. The data is stored and you can remove ser-
vices power without any problems.
Restore
Menu to start restore of the modified parameters. If during the various parameter changes you want to return to the previous general
situation (i.e. to the last storage), you can use this menu to restore all the parameters. Follow these points to do this:
1. Using the buttons on the front, reach the “Memo Parameters → Restore” menu.
2. In the bottom line is the words “UP to confirm”. Press the”
►" button to enter the "change parameter" mode.
3. The
“
” character
appears in the lower left
corner of the display. At this point press “▲” (i.e. UP).
4. Start the recovery phase indicated by the words “Wait....”. At the end appears the inscription “OK” indicating that the opera-
tion is finished correctly.
5.
At this point, you can press “◄” to confirm and exit the “Edit Parameter mode”. The parameters have been changed and
brought back to the situation of the last memorisation.
NOTE:
If it is necessary to return all the parameters to the factory values (Global Reset), the buttons “▲” and ”▼“ must be
pressed simultaneously before supplying the services; by holding down the buttons, power the services and when the writing ap-
pears on the LCD display you can release the buttons. At this point you have restored the factory parameters but still have to be
stored using the menu “Memo Parameters → Save”.
I/O Configure
Menu group to
configure and calibrate analog or digital inputs and outputs.
Analog inputs
Menu group to configure and calibrate analog inputs. For simplicity it is advisable to see the following figure showing the internal
calibration structure of a generic analog input.
The voltage value on the input terminals is measured and represented by a value between -100 % and +100 % corresponding to the
voltage of -10Vcc and +10Vcc. Then the percentage value is added to a set value called “Offset” to eliminate the analog signal offset
error. The result is multiplied by a setable value called “Gain”. In addition, the AI1 input also has the possibility to reverse the sign
with a setting in the menu; this can be useful when the motor rotates contrary to the desired. The result is then limited as full scale to
±100 % and indicated as the output value of the “Value” block. By means of these parameters it is possible to compensate for any
gains and offsets errors that are present in the signal provided from the outside.
Analog input X
Menu group to configure the analog input X. Changes to the calibration values made in this group, act only on the indicated analog in-
put and not on the others.
An.Inp. X dest
Parameter that allows you to select the destination of the “Value” signal; using the keys you can select the destination among these:
