Fanuc Parameters
The following Fanuc control parameters must be set to successfully communicate
with the Haas rotary control.
Baud Rate
1200 (Initial setting. Change this only after interface
is functioning.)
Parity
Even (Required setting)
Data Bits
7 or ISO (If CNC control defines Data bits as word
length + parity bit, set to 8)
Stop bits 2
Flow control
XON / XOFF
Character Coding (EIA/ISO) ISO (Required setting, EIA will not work)
DPRNT EOB
LF CR CR (“CR” is required, “LF” is always ignored
by the servo control)
DPRNT
Leading zeroes as blanks - OFF
Be certain to set FANUC parameters related to the actual serial port connected to
Haas rotary control. The parameters have been set for remote operation. A program
can now be entered, or run an existing program. There are several key items
to consider to ensure your program will run successfully.
DPRNT must precede every command sent to the Haas Control.
The commands are sent to the controller in ASCII code and terminated by a carriage
return (CR).
All commands must be preceded by an axis select code (U, V, W, X, Y, Z). For
example, setting parameter 21 = 6, means Z will represent the axis code.
RS 232 Command Blocks
DPRNT[ ]
Clear/Reset receive buffer
DPRNT [ZGnn ]
Loads G-code nn into step no. 00, “0”is a place holder
DPRNT[ ZSnn.nnn ] Loads Step Size nnn.nnn into Step no. 00
DPRNT[ ZFnn.nnn ] Loads Feed Rate nnn.nnn into Step no. 00
DPRNT[ZLnnn] Loads Loop Count into Step no. 00
DPRNT[ZH]
Return home immediately without M-FIN
DPRNT [ZB]
Activates Remote Cycle Start without M-FIN
DPRNT [B]
Activates Remote Cycle Start without M-FIN regardless
of Haas Servo Control Parameter 21 setting (Not for
Notes:
general use in this application)
1. Use of “Z“ above assumes Haas Servo Control Parameter 21 = 6.
2. Leading and trailing “0” must be included (correct: S045.000, wrong:
S45).
