SETINGS
50 Aux Axis Sync
This changes the synchronization between sender and receiver for the second serial second serial port is used for auxiliary settings between C control and the auxiliary axes must be the same.
Selecting “RTS/CTS” will tell the sender to temporarily stop sending data while the receiver catches up.
Selecting “XON/XOFF” uses ASCII character codes from the receiver to tell the sender to temporarily is the mon setting.
The “DC CODES” selection is like XON/XOFF, with the exceptions that start/stop codes are sent.
The “XMODEM” selection is receiver-driven, which sends data in blocks of 128 gives the RS-munication added reliability because each block is checked for integrity.
51 Door Hold Switch Override (Safety Switch Override)
Selecting “OFF” will not allow a program to start when the doors are open, and opening a door will cause the running program to stop (the same as pressing Feed Hold).
Machines equipped with a hand held safety switch will go into feed hold if the safety switch is released.
When the control is powered on, this setting automatically returns to OFF.
52 G83 Retract Above R
(Range to inches or 0-761 mm).This setting changes the way G83 (peck drilling cycle) behaves. Most programmers set the reference (R) plane well above the cut to ensure that the chip clearing motion actually allows the chips to get out of the hole. However this wastes time as the machine will “drill” through this empty distance. 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.
53 Jog w/o Zero Return
Turning this setting ON allows the axes to be jogged without zero returning the machine (finding machine home).
This is a dangerous condition as the axis can be run into the mechanical stops and the possibly damage the machine.
When the control is powered up, this setting automatically
