LOGIC CNC INPUTS AND OUTPUTS
SOFT: V02.2X
General logic inputs
LATCHM (M5011)
This allows the type of JOG key operation to be selected in JOG mode.
If the PLC sets this signal low, the axes will only move while the corresponding JOG key is pressed.
If the PLC sets this signal at a high logic level, the axes will move from the moment the corresponding
JOG key is pressed until the STOP key or other JOG key is pressed. In this case, the movement
will be transferred to that indicated by the new key.
MACHMOVE (M5012)
When working with coordinate transformation of inclined planes, the axes movements are made with
respect to the axes of the part
To make the jogging movements by handwheel or keyboard along the axes of the machine, use
G53 or activate the general CNC input "MACHMOVE (M5012) at the PLC.
MACHMOVE = 0 The movements coincide with the axes of the part.
MACHMOVE = 1 The movements coincide with the axes of the machine.
See the chapter on "Coordinate Transformation" in the programming manual.
ACTGAIN2 (M5013)
The axes and the spindle can have 3 sets of gains and accelerations.
By default, the first set is always assumed. The one indicated by the axis and spindle parameters:
ACCTIME (P18), PROGAIN (P23), DERGAIN (P24) and FFGAIN (P25).
general parameter ACTGAIN2 (P108) indicates with which functions or in which mode the second
set is applied, the one set by axis parameters ACCTIME2 (P59), PROGAIN2 (P60), DERGAIN2
(P61) and FFGAIN2 (P62) or spindle parameters ACCTIME2 (P47), PROGAIN2 (P48), DERGAIN2
(P49) and FFGAIN2 (P50).
The gains and accelerations can also be changed from the PLC regardless of the active operating
mode or function. To do this, use general input ACTGAIN2 (M5013).
ACTGAIN2 (M5013) = 0 The CNC assumes the first set.
ACTGAIN2 (M5013) = 1 The CNC assumes the second set.
RESETIN (M5015)
This signal will be treated by the CNC when the JOG mode is selected and there is no movement
of the axes or when a program to be executed is selected and it is not running.
When there is a rising edge (leading edge) of this signal (change from low to high) the CNC assumes
the initial machining conditions selected by the machine parameter.
The CNC will indicate by means of the general logic output RESETOUT that this function has been
selected.
The treatment received by this signal is similar to that given to the RESET key on the front panel.
AUXEND (M5016)
This signal is used in the execution of auxiliary functions M, S and T, to tell the CNC that the PLC
is executing them.
The change of gains and accelerations is always made at the beginning of the block.
When working in round corner (G5), the change does not take place until G07 is
programmed.
