M-Series Operator’s Manual 4/9/15
M102 - Restart Program
M102 performs any movement requested, and restarts the program from the first line. The Z-axis is NOT moved to
the home position, and the operator is NOT prompted to press the CYCLE START button to continue.
M103 - Programmed Action Timer
M103 is used to set up the time limit for a timed operation. If the timer is canceled (usually by M104) before the
specified time limit , the program will be canceled and the message "Programmed action timer expired" will be
displayed. If another M103 is issued before the time limit expires, then this time limit is nullified and the new time
limit will be set up as specified by the latest occurring M103. Note also that if M0 or M1 causes the program to
stop momentarily and the “M0 jogging” feature is enabled, then the the timer will also be canceled without the need
to issue M104.
Example: Activate a device and wait for a response. If there is no response within 4.5 seconds, cancel the
program.
M94/12 ; turn on input request 12
M103/4.5 ; start 4.5 second timer
M100/4 ; wait for input 4 to open
M104 ; input 4 opened, cancel timer
M104 - Cancel Programmed Action Timer
M104 stops the timer started by the last M103 executed.
M105 - Move Minus to Switch
M105 moves the requested axis in the minus direction at the current feedrate until the specified switch opens (if the
given P parameter is positive), or until the scecified switch closes (if P parameter is negative).
Example:
M105/X P5 F30 ; move the X axis in minus direction at 30"/min until
; the switch on INP5 opens
G92 X10 ; Sets X position to 10
M105/Z P-6 ; move the Z axis in minus direction until switch on INP6 closes
M106 - Move Plus to Switch
M106 moves the requested axis in the plus direction at the current feedrate until the specified switch opens (if the
given P parameter is positive), or until the scecified switch closes (if P parameter is negative).
Example:
M106/Z P3 F30 ; move the Z axis in the plus direction at 30"/min, until
; the switch on INP3 opens
G92 X10 ; Sets Z position to 10
M106/X P-3 ; move the X axis in the plus direction until the switch on INP3 closes
M107 - Output Tool Number
M107 sends the current tool number to the automatic tool changer, via the PLC. M107 does not set the tool changer
strobe or look for an acknowledgement from the changer (see M6).
Example:
M107 ; send request for tool to change
M94/16 ; turn on tool changer strobe
M101/5 ; wait for acknowledge on input 5
M95/16 ; turn off strobe
M100/5 ; wait for acknowledge to be removed
