4th and 5th Axis Drive - Installation - NGC

AD0319

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

Electrical Safety

 Caution: When you do maintenance or repair on CNC machines and their components, you must always follow basic safety precautions. This decreases the risk of injury and mechanical damage.

  • Set the main circuit breaker to the [OFF] position.

 Danger: Before beginning any work inside the control cabinet the High Voltage indicator light on the 320V Power Supply / Vector Drive must have been off for at least 5 minutes.

Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about doing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.

Rotary Scale Cable - Installation

Machine Compatibility:  Next Generation Control Machines with a trunnion rotary.

Document Applies to these Parts:

[A] 32-10053 QTY: 1 CABLE, [+12V] ROTARY SCALE FEEDBACK CONTROL END (NGC)

[B] 41-0040 QTY: 4 BOLT, PTHS 4-40X3/8 TRUSS MCMASTER-CARR

1

Find the plug [1] for the 4th-AXIS SCALE / A-AXIS SCALE or 5th-AXIS SCALE / B-AXIS SCALE receptacle. The plug is on the side of the control cabinet. Pull the plug out of the hole.

Connect the 28-pin connector [2] from the rotary scale feedback cable to the receptacle. Use the (4) 4-40 screws [3].

2

Remove the center cable track cover and the track cover below the MainCon PCB.

Remove the MainCon PCB cover.

Route the 4th-AXIS SCALE / A-AXIS SCALE or 5th-AXIS SCALE / B-AXIS SCALE cable [1] as shown.

Connect the 11-pin connector of the rotary scale feedback cable to the correct connector on the MainCon PCB:

  • 4th-AXIS SCALE / A-AXIS SCALE Scales Channel 12A (P36)
  • 5th-AXIS SCALE / B-AXIS SCALE Scales Channel 13A (P37)

Install the covers.

4th Drive - Installation - Mill

1

Find the (2) plugs [1] for the 4th-Axis / A-Axis receptacles. The plugs are on the side of the control cabinet. Push the plugs out of the holes.

Install the 7-pin power connector [2] into the receptacle that has the label 4th-AXIS POWER / A-AXIS POWER. Use the (4) screws.

Install the 28-pin encoder connector [3] in the receptacle that has the label 4th-AXIS ENCODER / A-AXIS POWER. Use the (4) screws.

Remove the I/O PCB cover.

Remove the Maincon PCB cover.

2

Find the location on the amplifier bank that has the A Axis / 4th Axis label. Install the amplifier for the fourth-axis drive at this location.

Connect the fourth-axis servo cable wires to the high-voltage terminals on the amplifier:

  • red to RED [1]
  • white to WHT [2]
  • black to BLK [3]

Connect jumpers [4] from the fourth-axis drive to the nearest amplifier on each side:

  • Connect the black wire to -H.V..
  • Connect the red wire to +H.V..

 Caution: On older machines the fourth-axis servo cable may have a shielded wire attached to the black jumper. Connect the shielded wire to -H.V. Do not connect it to the machine ground.

Put the cables in the cable tray.

3

Connect the 3-pin connector [1] on the A-Axis brake cable to P16 [2] on the I/O PCB.

Connect the 16-pin connector [4] on the encoder cable to Encoder Channel 4 (P20) [3] on the Main Control PCB.

Connect the 8-pin connector [5] on the current-command cable to the Amplifier Channel 4 (P4) socket [6] of the Main Control PCB.

Connect the 8-pin connector [7] on the current-command cable to the ampifier [8].

4

Remove the blanking plate [1].

Install the clamp block mount [2].

Put the rotary cables through the clamp block [3].

Install the clamp block retainer [4].

5

If you are not installing a fifth-axis drive, install the cover plates for the Maincon PCB and I/O PCB.

Set the main circuit breaker to the ON position.

Push [POWER ON].

Refer to: Next Generation Control - Option Activation Code to enable the fourth axis software.

5th Drive - Installation - Mill

1

Find the (2) plugs [1] for the 5th-Axis / B-Axis sockets. The plugs are on the side of the control cabinet. Pull the plugs out of the holes.

Install the 7-pin power connector [2] in the location that has the label 5th-AXIS POWER / B‑AXIS POWER. Use the (4) screws.

Install the 28-pin encoder connector [3] in the location that has the label 5th-AXIS ENCODER / B-AXIS ENCODER. Use the (4) screws.

Remove the I/O PCB cover.

Remove the Maincon PCB cover.

2

Find the location on the amplifier bank that has the B Axis label. Install the amplifier for the fifth-axis drive at this location.

Connect the fifth-axis servo cable wires to the high-voltage terminals on the amplifier:

  • red to RED [1]
  • white to WHT [2]
  • black to BLK [3]

Connect jumpers [4] from the fifth-axis drive to the nearest amplifier on each side:

  • Connect the black wire to -H.V..
  • Connect the red wire to +H.V..

 Caution: On older machines the fifth-axis servo cable may have a shielded wire attached to the black jumper. Connect the shielded wire to -H.V. Do not connect it to the machine ground.
