Input description
The positioner is controlled by 4 opto-isolated inputs, that are:
START:
active from NA to NC, it causes the positioning start and brings different effects according to
the working mode (see working mode at page 4).
EMERGENCY: it must be normally closed, if open it blocks or interrupts the positioning
PIECECOUNTER: at the end of each positioning the instrument expects a changing over of the piece counter
input from NC to NA to proceed to the next positioning. NB: if not used connect it in parallel
with the
START
input.
PRESET:
the changing over from NA to NC causes the reset or the preset loading according to the
zero reset procedure constant (see zero reset procedure page 6).
For switches see the connections scheme at page 10.
Output descriptions
The positioner is able to manage 3 relays outputs:
START/STOP:
normally open switch that closes to allow positioning
FORWARD/BACKWARD:
change-over switch that controls the direction of motion of the positioned axis
END POSITIONING:
normally open switch that closes at positioning end
ANALOG OUTPUT
voltage selectable 0÷10V or –10÷10V, and current 4-20mA
For switches see the connections scheme at page 10
PROGRAMMING
The following keys are used to programme:
PGM
to start and to leave the programming mode of the instrument
to change from one constant to another or to increase the digit value during modification
or to change from one digit to the next one
RESET/ENTER
to confirm inserted values
To enter programming mode is necessary to press the
PGM
key ; on the display you will see the
write
(immediate positioning); by the key you can run through the menus
