10.3 Spindle logic inputs.
LIMIT+S (M5450) | LIMIT-S (M5451) main spindle
The CNC uses this signal while searching home when the spindle changes to working in closed loop
(M19). The CNC only considers the signals for the currently selected spindle.
The PLC sets one of the signals high to tell the CNC that the spindle has overrun its range of travel
in the positive (+) or negative (-) direction.
In this case, the CNC stops axis feed and spindle rotation and displays the corresponding error on
screen.
DECELS (M5452) Main spindle
The CNC uses this signal while searching home when the spindle changes to working in closed loop
(M19). The CNC only considers the signals for the currently selected spindle.
The PLC sets this signal high to indicate to the CNC that the reference search switch is pressed.
When this signal is activated in the reference search mode the CNC decelerates the spindle,
changing the rapid approach speed indicated by the s.m.p. REFEED1 (P34), with the slow feedrate
indicated by the s.m.p. REFEED2 (P35). After decelerating, it accepts the following reference signal
from the spindle feedback systems as being valid.
SPDLEINH (M5453) Main spindle
The CNC considers these 2 signals at all times so both spindles can be controlled by the PLC.
When the PLC sets this signal high, the CNC outputs a zero velocity command for the spindle.
SPDLEREV (M5454) Main spindle
The CNC considers these 2 signals at all times so both spindles can be controlled by the PLC.
When the PLC sets this signal high, the CNC reverses the programmed spindle turning direction.
If while being this signal high, a block containing an M3 or M4 is executed, the spindle will start turning
in the opposite direction.
SMOTOFS (M5455) Main spindle
The SMOTIME (P46) filter set for the spindle with parameter P46 can be canceled from the PLC.
This SMOTIME filter will be activated or deactivated at the beginning of the block. If one of these
logic inputs is activated or deactivated while the CNC is overlapping blocks being executed in round
corner, it will be ignored until that operation is finished.
SERVOSON (M5457) Main spindle
These signals are controlled by the PLC and the CNC will process them only when the spindle is
working in closed loop (M19). Its treatment depends on the value assigned to s.m.p. DWELL (P17).
DWELL = 0
If s.m.p. DWELL (P17) has been set to "0", the CNC will check the status of the SERVOSON signal
at the time when the ENABLE signal is to be output.
