45 MIRROR IMAGE X-AXIS
46 MIRROR IMAGE Y-AXIS
47 MIRROR IMAGE Z-AXIS
48 MIRROR IMAGE A-AXIS
These are On/Off settings. When it is off, axes motions occur normally. When it is on, the specific axis motion
is mirrored (or reversed) around the work zero point.
49 SKIP SAME TOOL CHANGE
This is an On/Off setting. When it is off, an M16 will always cause a tool change sequence to occur; even if
the same tool is put back into the spindle. When it is on, a tool change to the same tool as is in the spindle
will cause no action.
50 AUX AXIS SYNC
This changes the synchronization protocol between sender and receiver for the second serial port. When set
to RTS/CTS, the signal wires in the serial data cable are used to tell the sender to temporarily stop sending
data while the receiver catches up. When it is set to XON/XOFF, those ASCII character codes are used by the
receiver to tell the sender to temporarily stop. XON/XOFF is the most common setting. Make sure that the
Haas servo control is set to the same condition.
DC CODES is like XON/XOFF but the paper tape punch or reader start/stop codes are sent. XMODEM is a
receiver-driven communications protocol that sends data in blocks of 128 bytes. XMODEM gives the RS-232
communication added reliability because each block is checked for integrity. Refer to "Data Input/Output"
section for more information.
51 DOOR HOLD OVERRIDE
This is an On/Off setting. When it is off, a program cannot be started when the doors are open and opening the
doors will cause a running program to stop just like in FEED HOLD. When it is on, and Parameter 57 bits
DOOR STOP SP and SAFETY CIRC are set to zero, the door condition is ignored. When the control is turned
on, this setting is set to Off.
52 G83 RETRACT ABOVE R
This is a numeric entry in the range of 0.0 to 9.9999 inches. This setting changes the way G83 and G73 works
when it returns to the R plane. Most programmers set the R plane well above the cut to ensure that the chip
clear motion actually allows the chips to get out of the hole but this causes a wasted motion when first drilling
through this "empty" space. If Setting 52 is set to the distance required to clear chips, the R plane can be put
much closer to the part being drilled. When the clear move to R occurs, the Z will be moved above R by this
setting.
53 JOG W/O ZERO RETURN
This is an On/Off setting. When it is off, jogging of an axis is inhibited until the zero return operation is com-
pleted. When it is ON, jogging of an axis is allowed prior to the zero return. The ON condition can be danger-
ous in that an axis can be run into the stops, however, the maximum speed allowed is one inch per minute or
0.0010 inches per handle increment. When the control is turned on, this setting is set to OFF.
54 AUX AXIS BAUD RATE
This setting allows the operator to change the serial data rate for the second serial port. This applies to the
interface with the optional C, U, V, and W axes. The possible values include: 50, 110, 200, 300, 600, 1200,
2400, 4800, 7200, 9600, 19200, 38400. Note that 4800 is standard in Haas servo controls and this should be
set to the same value.
