Conversational-style templates for easy tool-setting operations
No macro programming required for operation
Outputs G-code to MDI, where it may be edited, or transferred into a program
Includes User-Definable Macros option
Includes Haas Visual Part Programming System

Machine Requirements:

Non-compact ATP [1]
Compact ATP [2]

Symptom Table

Symptom	Possible Cause	Corrective Action
The tool probe does not beep/activate.	The macros are corrupted.	Reload the macros
Incorrect measurements.	The probe is not calibrated.	Calibrate the probe. See Calibration section below for more information.
Compact ATP built before June 22, 2023 Only: The tool probe deploys and retracts slowly.	The actuator's dampener is too strong.	Replace the stronger dampener with weaker dampener 59-2164. See Dampener Replacement section below for more information. Note: This does not apply to the ST-40 and ST-45 compact ATPs.
Alarm 808 AUTOMATIC PROBE ARM FAULT	The probe arm failed to extend or retract.	Check for tools or parts in machining area that block motion of probe arm. Check for sufficient air pressure and volume. Check probe arm mechanism for broken parts, damaged air lines, or broken electrical connections.
Alarm 809 PROBE ARM SWITCH FAULT	The switch signals indicated both switches simultaneously or one of the switches indicates an unexpected position.	Check the switches and trip flags for damage and the switch wiring for damage.
Alarm 9159 SPINDLE MOTION REQUESTED WHILE PROBE ARM EXTENDED	The probe arm is extended.	Retract the probe arm. If the probe arm is retracted, troubleshoot the probe arm position switches.
Alarm 9974 PARTS CATCHER WILL COLLIDE WITH PROBE ARM	The probe arm is extended.	Retract the probe arm. If the probe arm is retracted, troubleshoot the probe arm position switches.
Alarm 9976 PROBE ARM WILL COLLIDE WITH PARTS CATCHER	The parts catcher is extended.	Retract the parts catcher. If the parts catcher is retracted, troubleshoot the parts catcher position switches.
Macro Alarm 1081 ILLEGAL TOOL OFFSET NUMBER T	Tool offset ‘T0' is not allowed.	If using the ‘T’ input on the cycle call line check the value is not zero (0), otherwise this alarm may occur if no tool or tool offset was selected in the MDI mode before running the cycle. Caution: Make sure the turret is safely away from the probe stylus before indexing the turret.
Macro Alarm 1082 ILLEGAL TOOL NOSE VECTOR H	Only vector numbers 1 to 8 are allowed.	Check and correct the ‘H’ input if used, or the ‘T’ address on the tool offset page.
Macro Alarm 1083 INPUTS C H1 – H4 MIXED	Can not use a cutter using the ‘C’ input with a corner vector H1–H4 specified.	Edit the program to not set a cutter using the ‘C’ input with a corner vector H1–H4 specified.
Macro Alarm 1091 FORMAT ERROR	An input has been omitted from the command line or when two inputs have been mixed.	Edit the program and restart from the beginning. Refer to the macro programming section of the Renishaw Manual for the relevant inputs required.
Macro Alarm 1092 PROBE OPEN	The stylus is in contact with the surface before the skip move begins.	Return to reference and edit the part program. If the stylus remains in an open (triggered) condition during any part of the cycle, the PROBE OPEN alarm is raised. Check that the stylus is not in contact with the surface or check to see whether vibration is causing it to unseat during a move. The alarm may also be raised at the start of a macro if the probe system is in error (a probe open signal condition is forced by the Renishaw interface). Check to make sure that the probe system is switched on in time before a skip move begins. A program dwell may be required. Check that the status LED on the interface is changing state when the stylus is deflected. If this does not happen, contact the supplier of the system for assistance.
Macro Alarm 1093 PROBE FAIL	The expected surface is not contacted within the overtravel of the probe.	Check the program and edit where necessary. Check that the probe stylus has been calibrated on the machine. Check that the status LED on the interface is changing state when the stylus is deflected. If this does not happen, contact the supplier of the system for assistance.
Macro Alarm 1099 PROBE FAIL	The tool length error exceeds the programmed Mm tolerance.	The programmed value must be half the total tolerance.
Probe Arm fails repeatability	ATP spur gear was not clocked correctly with regards to the rotary actuator.	Refer to the ATP Repeatability Test section below.
	Excessive gear sector movement	Refer to Gear Sector section below
	Inconsistent air pressure during arm deployment	Add an air regulator before the ATP actuation solenoid. Regulate the air pressure to 80 psi or lower.
	ATP arm deploys too violently
	ATP bounces when coming down to do tool touch offs	Refer to ATP Internal Hardware.

Calibration

Corrective Action:

The ATP needs to be calibrated anytime a stylus has been replaced or if the CNC control generates alarms during probe routines. Follow the ATP CALIBRATION procedure for calibrating the ATP.

Dampener Replacement

Remove the (x3) screws around the back ATP cover [1] .

NOTE: To make ATP cover removal easier, use a strong magnet to remove the cover.

On the inside of the ATP cover [1], remove the screws securing the dampener disk [2].

Install new dampener disk [2] on the ATP cover [1].

Install the ATP cover [1] back on the ATP base by mating the dampener [2] with the actuator shaft first.

Deploy and retract the ATP to make sure it works.

Repeatability Test

1

Check X-axis Repeatability

Press [FEED HOLD] while the probe is in the down position using M104.

Jog the turret with the turning stick in the active pocket 1 near the probe.

Hand Jog in .001" increments in the X-axis direction until the probe beeps.

2

Go to the [OFFSET] screen and record the value for pocket 1 on your traveler sheet.

Back the turret away from the probe.

Put the probe in the up position with M105 or RESET.

Put the probe back down again with M104.

Touch the tool off on the probe again in the X-axis direction.

Record the offset for pocket 1.

NOTE: Do this a total of 5 times for the X-axis measurement.

3

Check Z-axis Repeatability

Perform the repeatability test used on the X-axis for the Z-axis direction 5 times.

Readings cannot exceed 0.002" from each other.

If the probe does not repeat the readings and your machine was built before 09/06/2024, then refer to Automatic Tool Presetter - Installation - NGC - AD0434 to order a new ATP kit for your machine. Then refer to ATP - Probe Replacement - AD0632 to see the replacement procedure.

Machines experiencing the repeatability issue that were built after 09/06/24, refer to the Automatic Tool Presetter (ATP) - Alignment - Test - Calibration.

NOTE: If you continue to have issues with repeatability problems, please contact Haas Service for assistance.

Gear Sector

Remove the bearing cover [1] from the ATP assembly then remove the bolt [2[ and washer [1].

Gently pry and remove the arm and cap [1] from the base of the ATP assembly [2].

Note : Ensure that there is sufficient wire slack for the ATP probe before separating the two halves.

Ensure that the sector gear [3] does not have play and verify that bolts [1] and [2] are torqued to 30 in-lbs.

Important : During reassembly ensure that the actuator is clocked correctly so that play is minimized.

Note : Ensure that the air line to the actuator are disconnected

Rotate the actuator shaft [3] Clockwise until it stops.
Rotate the actuator shaft Counter-Clockwise slightly so that the land of the next tooth aligns with the mark.
