LOGIC CNC INPUTS AND OUTPUTS
SOFT: V02.2X
General logic inputs
M5054 = 1 "Path handwheel" or "path jog" function on.
CAXSEROK (M5055)
It must be used on the lathe model, when the "C" axis and the spindle share the same drive. See
"7.12 Digital servo (CAN or Sercos)" on page 363.
The PLC sets this signal high to let the CNC know that the drive is ready to work as a "C" axis.
EXRAPID (M5057)
The CNC only takes this signal into account if parameter RAPIDEN has been set to ·1· or ·2·.
If the PLC sets this signal high, the programmed movements are executed as follows.
"RAPIDEN" = 1 When the mark is activated, the programmed movements are executed
in rapid. There is no need to press the "rapid" key.
RAPIDEN = 2 When the mark is activated, the "rapid" key is enabled. The key must be
pressed to make movements in rapid; in other words, both the key and the
mark must be active.
When the signal is set back low, the movements are executed at the programmed feedrate.
The treatment which this signal receives is similar to that given to the rapid feedrate key on the control
panel.
The MANRAPID (M5009) signal is similar, but for movements in jog mode.
FLIMITAC (M5058)
When the PLC sets this signal high, it limits the feedrate of each axis to the value set by its axis
parameter"FLIMIT (P75)". When this limit is canceled, the CNC recovers the programmed feedrate.
SLIMITAC (M5059)
When the PLC sets this signal high, it limits the spindle speed to the value set by its spindle parameter
"SLIMIT (P66)". When this limit is canceled, the CNC recovers the programmed turning speed.
When the spindle is controlled by the PLC by means of the PLCCNTL mark, this limit is ignored.
BLOABOR (M5060)
When the PLC sets this mark high, the CNC ends the movement in progress and starts executing
the next block. If the interrupted block had M functions to be executed after the block, they will be
executed before going on to the next block.
This mark only affects the execution in automatic mode and the simulation with motion.
This mark does not stay active after the execution. Once executed, the CNC deactivates it. Likewise,
if they are activated in a block that does not accept them, they will also be deactivated; they do not
stay active for the next block.
These marks affect the following functions.
• It affect motion blocks G0, G1, G2, G3.
• They affect the dwell programmed with G4.
• It affects the look-ahead. In this type of programs with very small blocks, it is not possible to stop
at the same block where the "BLOABOR" mark is detected. In these cases, it will be canceled
at the block where the axis is fully decelerated.
