Axis Assignments

The axis parameters on machines with the Next Generation Control are designated in groups. The number that precedes the period designates the axis. The number that follows the period is the parameter group number. The following table shows the axis assignments for the axes on a mill or lathe.

Motion Axis NGC Axis Label Axis Parameter Group Physical Input/Output Connector Mill or Lathe Specific
X X 1.xxx 1 Mill/Lathe
X(2) GM X(Slave) 1.xxx 8 Mill
Y Y 2.xxx 2 Mill/Lathe
Z Z 3.xxx 3 Mill/Lathe
Main Spindle S 4.xxx 6 Mill/Lathe
Secondary Spindle SS 12.xxx 14 Lathe
A A 5.xxx 4 Mill
Tool Turret TT 9.xxx 7 Lathe
B B 6.xxx 5 Mill

Axis Parameters

The following screenshot shows the grid offset parameter group. The group number for grid offset parameters is 140 and the number that precedes it is the axis designation. For example, parameter 1.140, is the grid offset parameter for the X Axis.

Axis Alarms

The axis alarms for machines with the Next Generation Control are similar to parameter groups. They are similar to parameter groups in that one alarm group number is used for all of the axes. The axis at fault is designated by the number before the period. The alarm group number is the number after the period.

You must troubleshoot all of the axis alarms as you would the same alarm on a machine with the Classic Haas Control (CHC).

The following table compares some Servo Overload alarms on a Classic Haas Control machine with the same alarm on a Next Generation Control machine. All of the other axis alarms follow the same structure.

 Note: CHC Alarms 109, 110, 111, 188, 271, 674, along with other Servo Overload alarms, will not appear on a NGC machine. They are all replaced by Alarm group number 108 and are differentiated by the axis designation number that precedes the period.

CHC Servo Overload Alarms NGC Servo Overload Alarms
Alarm 108 - X SERVO OVERLOAD Alarm 1.108 - X AXIS SERVO OVERLOAD
Alarm 109 - Y SERVO OVERLOAD Alarm 2.108 - Y AXIS SERVO OVERLOAD
Alarm 110 - Z SERVO OVERLOAD Alarm 3.108 - Z AXIS SERVO OVERLOAD
Alarm 111 - A SERVO OVERLOAD Alarm 5.108 - A AXIS SERVO OVERLOAD
Alarm 188 - B SERVO OVERLOAD Alarm 6.108 - B AXIS SERVO OVERLOAD
Alarm 271 - C SERVO OVERLOAD Alarm 7.108 - C AXIS SERVO OVERLOAD
Alarm 674 - TT SERVO OVERLOAD Alarm 11.108 - TA AXIS SERVO OVERLOAD
