INHIBIT1 (M5103) INHIBIT2 (M5153) INHIBIT3 (M5203)
The PLC sets one of these signals at a high logic level in order to tell the CNC to prevent any
movement of the corresponding axis. This movement will continue when the PLC sets this signal
at the low logic level once more.
If the inhibited axis is moving together with other axes, all these stop moving until the signal returns
to the low logic level.
MIRROR1 (M5104) MIRROR2 (M5154) MIRROR3 (M5204)
If the PLC sets one of these signals at a high logic level, the CNC applies mirror image to the
movement of the corresponding axis.
It must be borne in mind that if this signal is activated during a programmed movement, the CNC
will only apply mirror image to the movement, not to the final coordinate.
If, when executing the programmed movement in block N20 the signal corresponding to the X axis
"MIRROR1" is active, the CNC will apply mirror image to the remaining movement in X.
This way, the new end of travel point will be X40 Y60.
By means of the activation of these signals, symmetrical parts can be executed by using a single
program, for example, soles of shoes.
In order to obtain the same effect as functions G11, G12, G13 and G14, it is necessary for the
corresponding axis or axes to be positioned at part zero when these signals are activated.
SWITCH1 (M5105) SWITCH2 (M5155) SWITCH3 (M5205)
When having 2 axes controlled by the same servo drive, this mark may be used to toggle the velocity
commands between the two axes.
DRO1 (M5106) DRO2 (M5156) DRO3 (M5206)
These inputs, together with the corresponding "SERVOON" inputs make it possible to operate with
the axes as DRO.
In order for the axis to work in DRO mode, its "DRO" input must be high and its corresponding
"SERVOON" input must be low.
When an axis works as a DRO, the positioning loop is open and its following error is ignored while
in motion
If the DRO signal is brought back low, the axis will no longer behave as a DRO and the CNC will
take as position value its current position assigning a 0 value to the following error.
