Setting 53 – Jog w/o Zero Return
When a Haas vertical machining is powered up using the power on key the machine has the
requirement to be taken home in the X, Y and Z axes. This is accomplished by first depressing the
orange RESET key which turns on the servo motors. Then the POWER UP blue key beside it must
depressed to take the machine to Home. At home the X, Y and Z machine coordinates are set to
zero. First the Z goes to home, then the X and Y go to Home position.
If a tool is engaged into a part when it was shut off a Z positive move may damage the tool or part
at start up. Setting 53 allows a jog movement to disengage the tool from a part before the
obligatory machine home process. This however puts the machine in a dangerous situation as
various axes could be run into the mechanical stop and damage the machine. After the tool is
jogged off a part using setting 53 it is obligatory that the machine be zero returned in all axes to
prevent damage to the machine.
Setting 142 – Offset Change Tolerance
This offset will create a warning pop up which will notify that an offset change more than the value
entered in this setting is issued. The message “Greater than Setting 142! Accept(Y/N)” will appear.
If a Y is entered the control will change the offset amount by the amount specified. If an N is
entered than the offset change will be ignored. Offset 142 will prevent inadvertent large offset
changes from being made which may possibly cause a crash.
Setting 156 – Save Offset with Program
When this setting is set to On the control will save the offsets when the program is saved.
The offset program is saved as O999999. In the program file it is saved after the M30 and before
the %. When this program is uploaded to the Haas control from a UBS device a prompt will appear
“LOAD OFFSETS? (Y/N)”.
