Setting 36 - PROGRAM RESTART - When it is OFF, starting a program from anywhere other than the
beginning of a program or a tool sequence may produce inconsistent results. When it is ON, you
are able to start a program from the middle of a tool sequence. You cursor onto the line you want to
start on and press CYCLE START. It will cause the entire program to be scanned to ensure that the
correct tools, offsets, G codes, and axes positions are set correctly before starting and continuing
at the block where the cursor is positioned. Some alarm conditions are not detected prior to motion
starting. You could leave this setting ON all the time if you want, but it might do some things
unnecessarily, so you would probably prefer to turning it OFF when you're done using it
Setting 51 - DOOR HOLD OVERRIDE - 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 turned ON, and Parameter 57 bits DOOR STOP SP and SAFETY CIRC are set to zero, this
door condition is ignored. When the control is turned off and then back on again, this is one of a
few settings that will switch back to its default condition, and will then be OFF when you power
up, so you will need to turn it ON again if that's what's needed.
Setting 77 - SCALE INTEGER F - This can be used to change how the control interprets a feed rate. A
feed rate that is entered in your program can be misinterpreted if you do not enter a decimal
point in the Fnn command. The selections for this setting are Default, which assumes a 4 place
decimal if no decimal point is entered (i.e., if you enter a 1, it assumes you mean 0.0001); Integer,
which assumes a whole number (enter a 1, it assumes 1.0); or .1 (enter 1, it assumes 0.1), .01 or
.001 (you get the idea), or .0001, which is the same as the Default setting.
Setting 84 - TOOL OVERLOAD ACTION - This is used to determine tool overload conditions as defined by
the Tool Load monitor page in the CURNT COMDS display (use PAGE DOWN to get there). A
tool overload condition can result in one of four actions by the control, depending on Setting 84.
ALARM will generate an alarm when overload occurs; FEED HOLD will stop with a Feed Hold
when overload occurs; BEEP will sound an audible alarm when overload occurs; or AUTOFEED
will automatically decrease the feed rate.
Setting 85 - MAX CORNER ROUNDING - This setting is used to set the corner rounding accuracy required
by the user. The accuracy defined in Setting 85 will be maintained even at maximum feed rate. The
control will ONLY slow at corners when it is needed . This setting defeats all the years of
discussion by competitors who say you need multiple blocks of look-ahead. The HAAS control
actually does look-a-head for block interpretation up to 20 blocks. This is NOT NEEDED for high
speed operation. It is instead used to insure that DNC program input is never starved AND to allow
cutter compensation to have non-XY moves inserted while cutter compensation is on.
Setting 88 - RESET RESETS OVERRIDE - When this is On, the RESET key sets all overrides back to 100%.
Setting 101- FEED OVERRIDE > RAPID - When this setting is OFF, the machine will behave normally.
When it is ON and HANDLE CONTROL FEED RATE is active, the jog handle will affect both
the feed rate override and the rapid rate override simultaneously. That is, changing the feed rate
override will cause a proportional change to the rapid rate. The maximum rapid rate will be
maintained at 100% or 50% according to setting 10.

Setting 103- CYC START / FH SAME KEY - This is really good to use when you’re carefully running through
a program. When this setting is ON, the CYCLE START button functions as the Feed Hold key as
well. When CYCLE START is pressed and held in, the machine will run through the program;
when it’s released, the machine will stop in a Feed Hold. This gives you much better control when
testing a new program. When you’re done using this feature, turn it Off. This setting can be
changed while running a program. It cannot be ON when Setting 104 is ON. When one of them is
turned ON, the other will automatically turn OFF.
