MA-5068-E MACRO 200 INSTRUCTIONS MANUAL
Notes on the editable values in the conversion table:
• The value for voltage must always be shown to one decimal place.
• Point 1 is the starting point for the speed ramp, and therefore the
voltage will always be 0, while the value for output RPM is editable.
• The possible values for each point must be equal to or greater than the
value corresponding to the previous point.
• Point 5 is the final point for the speed ramp, and therefore the voltage
will always be 10, while the value for output RPM is editable.
• It is not necessary to program the value for MAXIMUM RPM in this table.
• If, at any point, the maximum value for Vin = 10 V is entered, the
corresponding values for Vin and RPM at higher points will be
automatically updated according to the value for this point.
• If, at any point, the maximum value is entered, that is, RPM =
MAXIMUM RPM, the corresponding values for RPM at higher points will
be automatically updated to MAXIMUM RPM.
Programming speed ramp
To access this menu and program the different points corresponding to the
voltage-speed ratio, you must select external reference (‘ref ext’ LED is
illuminated) and press the right arrow key. Then the following message is
displayed:
The IN LED to the position ON and the OUT LED to the position OFF, 1 000,
NOT EDITABLE; press the right arrow to go to the next point:
The IN LED to the position OFF and the OUT LED to the position ON, 1 XXX,
which means that the output speed is being programmed for point 1 (when the
input voltage is 0 V); with the up/down arrow keys the value may be modified,
within a range from 000 to MAXIMUM RPM; press the right arrow key to go to
the next point:
The IN LED to the position ON and the OUT LED to the position OFF, 2 XXX ,
which means that the input voltage value is being programmed for point 2;
with the up/down arrow keys the value may be modified, within a range from
00.0 to 10.0 (to one decimal place); press the right arrow key to go to the next
point:
The IN LED to the position OFF and the OUT LED to the position ON, 2 XXX,
which means that the output speed value is being programmed for point 2;
