11.1 4th and 5th Axis Drive - Installation

4th and 5th Axis Drive - Installation - NGC

AD0319

Revision A - 10/2025

Introduction

Refer to the Rotary - Installation procedure to install a TR, TRT, or a T5C rotary unit on a Haas VMC.

Machine Requirements:
  • Mills that have brushless servo amplifiers.
  • Machines with NGC.

Document Applies to these parts:

  • P/N 93-2389 4TH-AXIS DRIVE, NGC
  • P/N 93-1000276 4TH-AXIS DRIVE
  • P/N 93-2544 5TH-AXIS DRIVE, NGC
  • P/N 93-1000275 5TH AXIS DRIVE

Note: All machines must be geolocated by a service technician when a 5th axis upgrade is installed and activated. 

Motion sensor support has been posted on HBC in HBC -> Service -> Utilities -> Documents and software -> 11_Geolocation & Motion Sensor.

Electrical Safety

 DANGER: Working with the electrical services required for CNC machines is extremely hazardous and can result in serious injury or death.

Before connecting line wires to the CNC:

  • Turn off all power to the machine at the source.
  • Perform a Lockout-Tagout (LOTO) procedure to ensure the power remains off during service.
  • Verify that power has been disconnected by using an AC voltage detector on all incoming lines.

If you are uncertain about how to safely disconnect power or perform LOTO procedures:

  • Do not proceed.
  • Contact qualified personnel or obtain appropriate assistance before continuing.

Failure to follow these precautions may result in electrical shock, equipment damage, or fatal injury.

 Danger: Before beginning any work inside the control cabinet, verify that the High Voltage indicator light on the 320V Power Supply / Vector Drive has been off for a minimum of five (5) minutes. This waiting period ensures that residual voltage has dissipated and reduces the risk of electric shock.

Certain service procedures involve high-risk electrical components and may pose serious injury or fatality hazards. Technicians must not attempt any procedure unless they have a complete understanding of the steps involved and the associated risks.

If there is any uncertainty regarding a procedure, contact your Haas Factory Outlet (HFO) to arrange for a qualified service technician.

11.2 Rotary - Enable and Disable

Rotary - Enable and Disable - NGC

Introduction

These procedures tell you how to enable, disable, and clear a rotary unit on a machine with the Next Generation Control:

Note: Rotary products equipped with a Sigma-7 motor require software version 100.17.000.2030 or higher for full 4th axis operation.

  • Next Generation Control - Rotary - Enable: Do this procedure after you install a rotary unit. This procedure tells you how to tell the control what rotary unit you installed.
  • Next Generation Control - Rotary - Disable: Do this procedure to temporarily disable the rotary axis while you keep the rotary axis configured.
  • Next Generation Control - Rotary - Clear: Do this procedure when you remove a rotary unit from the machine, and you must install a different rotary unit.

Rotary - Enable

Do this procedure after you install a rotary unit. This procedure tells you how to tell the control what rotary unit you installed. Do this procedure on a machine that has the Next Generation Control. This rotary selection tool replaces Setting 30 and 78 used on CHC controls. See enable Rotary axis - CHC for instructions. 

1

Push [POWER ON].

Push [SETTING].

Select the Rotary tab [1].

2

Highlight the 4th Axis rotary unit that is installed [1].

Push [ENTER] to Set Axis [2].

 Note: This screen shows the TR310-P4-TLT rotary.

Note:  If your rotary product does not appear in the list, the control may need to update the rotary configuration. Only Haas technicians can update configuration files. Contact your HFO to schedule the update and refer to the Update Rotary Configuration Files procedure.

NOTE: CONFIG FILE NAME INFORMATION

Single axis rotaries require one config file, while dual axis requires two files. 

All config file names are broken up into several parts separated by dashes. 

The first part is the model number of the rotary unit [1]. This can be found on the serial plate of the unit. Some Rotary units have a dash in their name, that dash may or may not be included in the file name. 

The next part of the file name is the P version number of the unit [2]. This can also be found on the serial plate of the unit.  

The next part of the files only appears on dual axis Rotaries. The next part is either "TLT" or "ROT" [3]. TLT applies to the 4th axis, and ROT applies to the 5th axis. Single axis rotaries will not have this part.

The last part of the name is an R at the end. Using this configuration file would make the Rotary turn in the opposite direction.

11.3 Reverse Rotary Direction Setup

Reverse Rotary Direction Setup - NGC

Revision B - 05/2026

Introduction

This procedure tells you how to load rotary files to reverse the rotary direction of your Haas rotary. The files supplied only apply to available Haas rotaries.

This procedure applies only to Haas rotaries on machines with software version 100.16.000.1030 and higher.

Note: Software version 100.21.000.1130 and later will not come with reverse rotary files.

This procedure will work for previous software versions that did not come with the desired reverse rotary file. Verify that your software is compatible with the rotary you wish to install. See Rotary - Compatibility and Servo Motor Configuration Identification for more information about rotary compatibility. 

Reverse Rotary Direction Setup - NGC

1

Download and extract the reverse rotary direction files. 

Note: The complete reverse rotary folder must be loaded. Do not load an individual reverse rotary file from within the folder, as the procedure will not complete correctly.

Download Rev_User_Rot.zip

Find your rotary model in the extracted folder and copy it to a USB memory device.

Insert the USB memory device with the rotary configuration file into the USB port on the control pendant.

Press [LIST PROGRAM] and navigate to the USB tab [1].

Select your reverse rotary file [2]. Press [ENTER]. 

Note: The reverse rotary files that are loaded with this procedure will have an R in the Name column. These files will have the same name in the Model column as normal rotary files. Reverse files preloaded with the software will end with -R in the Model column. 

Press [F2] to copy the reverse rotary file.

Navigate to User Data [3] on the Copy To screen.

2

Press the [RIGHT] CURSOR arrow to enter the User Data directory.

Navigate to the My Rotary directory.

Press the [RIGHT] CURSOR arrow to enter the My Rotary directory [1].

Press [ENTER] [2] to copy the rotary configuration file to this location.

3

Press [SETTING].

Navigate to the Rotary tab [1].

Type the model of your rotary and press [F1] to search. This example uses TRT210-P20 [2]. Reverse rotary files have the letter “R” in the Name column. Normal rotary files will be blank in the Name column.

Your reverse rotary file [3] is in the Select New Rotaries page.

Highlight the rotary files you want to activate and press [ENTER] to pull up the Select Table Orientation screen.
