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.

Put the cables in the cable tray.
