PRESET X / Y
The PRESET input is used to set, on the axis display, a position value previously
programmed in the configuration parameters (see parameter 09).
The input works in combination with the ZERO ENCODER input, as follows:
-
if the ZERO ENCODER input is not connected, when the PRESET input closes, the
value is loaded immediately;
-
if the ZERO ENCODER is connected, closing the PRESET input only allows to load
the preset value when the ZERO ENCODER signal is detected.
Connect a N.O. contact between the PRESET input and the COM+ of the concerned axis.
ZERO ENCODER
The ZERO ENCODER signal (active high) is used to set on the axis display a position
value previously programmed in the configuration parameters (see parameter 09).
The value is loaded only if the PRESET input is closed, therefore allowing the presetting
activation. Connect the Z channel of the encoder to its respective input.
AUX X / Y
The AUX input is used for special applications.
Connect a N.O. contact between the AUX input and the COM+ of the concerned axis.
OK POSITION
The OK. POS. output is used to signal that positioning has been performed correctly.
The output corresponds to a N.O. relay contact that opens during the axes movement and
closes after the check of the correct positioning within the tolerance range (see parameter
14). The waiting time before starting the positioning check is programmed in the
configurations parameters (see parameter 17). The output remains open if positioning is
not concluded correctly. If positioning is concluded correctly, the output opens at the end
of the counting of the cycle’s programmed repetitions (semi-automatic operation) or at the
end of the program (automatic operation).
ENABLING
The EN.MOV. output is used to enable the axes movements in any of the operating
modes: manual/semi-automatic/automatic. The output corresponds to a N.O. relay contact
that closes at the beginning of the axis movement and opens approximately 0.5 seconds
after the axis stops.
FEED / BACK
The FEED / BACK outputs are used to control the axes movements in the two directions,
in any of the operating modes: manual/semi-automatic/automatic. The outputs correspond
to N.O. relay contacts connected to their common COM FB; they alternatively close to
command the axis movement and they open to terminate the movement.
