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.

Symptom Table

Symptom Probable Cause Corrective Action
Alarm 161 - 164 AXIS DRIVE FAULT.

Alarm 993 AMPLIFIER SHORT CIRCUIT

Faulty servo amplifier. Check the corresponding amplifier assembly.

Refer to Servo Amplifier - Troubleshooting Guide to troubleshoot the amplifier.

Faulty power cable. Inspect the cables and connectors. Refer to the Power Cable section below.
Faulty servo motor. Check the corresponding servo motor. Refer to Servo Motor section below.

Alarm 103 - 105, 270, 709 AXIS SERVO ERROR TOO LARGE.

Faulty encoder cable/connection or faulty encoder. Inspect the cables and connectors. Refer to the Main Processor/Encoder Cable section below. Check the encoder steps/revolution versus and ball screw pitch and verify the encoder counts are accurate per each rotation.
The axis motor brake, is not disengaging when servos are enabled. See the Motor Brake section below:
The axis ballscrew is damaged. Check the corresponding axis ballscrew.

Refer to Ballscrew - Troubleshooting Guide to troubleshoot the ballscrew.

Classic Haas Control Only - The machine parameters are not correct. Make sure you have the correct parameters for the type of axis motor.
  1. Determine if machine has Sigma-1 or Sigma-5 motors.

    Note: The Sigma-5 axis motor have a push-lock connector for the encoder plug.

  2. Run parameter checker and select either Sigma-1 or Sigma-5 option.

Alarm 103 - 105 AXIS SERVO ERROR TOO LARGE, during the zero return process. The axis zero returns in the wrong direction.

The home sensor is being made during the zero return process causing the axis to zero return in the opposite direction. Check the axis home switch to make sure there are no metal chips on top of the sensor.
Alarm 135 - 137 AXIS MOTOR OVERHEAT. Faulty encoder cable/connection or faulty encoder. Inspect the cables and connectors. Refer to the Main Processor/Encoder Cable section below. Check the encoder steps/revolution versus and ball screw pitch and verify the encoder counts are accurate per each rotation..
The Mocon/Maincon PCB axis channel is defective. Swap the Encoder/Drive channels with another axis, if the alarm stays with the encoder/drive channel then the Mocon/Maincon PCB is defective.
The low-volt-power-supply is defective. Check the +5V / +12V / -12V DC voltages going to the Mocon/ Maincon PCB.
The parameter OVER TEMP NC bit 14 for the axis is incorrect. Make sure this parameter bit is set correctly. This is normally a 1.

Alarm 139 - 142 190, 273 MOTOR Z FAULT.

Alarm 153 - 156 Z CHANNEL MISSING

Alarm 182 - 185, 194, 278 AXIS ENCODER CABLE FAULT.

Alarm 217, 218, 219 AXIS PHASE ERROR

Alarm 224 - 228 AXIS TRANSITION FAULT

Faulty encoder cable or connection. Inspect the cables and connectors. Refer to the Main Processor/Encoder Cable section below.
Faulty encoder on servo motor. Check the motor for coolant contamination. Check the encoder steps/revolution versus and ball screw pitch and verify the encoder counts are accurate per each rotation.

Power Cable

Corrective Action:

Make sure the cables are connected correctly to the corresponding amplifier. Inspect the connector at the motor. Look for loose connections or contamination.

Look for signs of damage or stiffness on the cable. Disconnect the power cable from the amplifier and motor. Measure the resistance from leg to leg, and from leg to ground. Make sure the measurements result in an open connection. Check each leg from one end of the cable to the corresponding leg on the other end of the cable for continuity. If there is an open connection, there is a problem with the cable.

Servo Motor

Corrective Action:

Make sure the motor's connectors are not contaminated. Disconnect and inspect the power cable connector at the motor. Make sure that there is no coolant contamination. Coolant contamination can generate drive fault alarms and damage the amplifier. Measure the resistance from the pins labeled A, B and C at the motor connector to chassis ground.

  • The reading must show an open circuit.
  • If the reading does not show an open circuit, the servo motor is at fault.

Main Processor/Encoder Cable/Encoder

Corrective Action - Main Processor/Cable:

Examine the connector [1] on the Maincon or MOCON PCB. Make sure it is not damaged.

Examine the cable. Look for signs of damage or stiffness. The connector [4] has two housings [2,3] for the cable pins.

Measure the resistance on the encoder cable from leg to leg, and from leg to ground. Make sure each measurement results in an open connection.

Make sure the cable is firmly connected at both ends. Reseat both connections. Make sure the cable is installed in the correct connector at the Maincon or MOCON PCB.

Corrective Action - Servo Motor Encoder:

Check the encoder steps/revolution in the configuration file. Jog the axis and based on the distance the ball screw travels per revolution (ball screw pitch), verify the encoder counts are accurate per each rotation. View the diagnostic>axis page as you jog the axis. The raw encoder count will show you how many encoder steps have been counted.  The z axis channel will also show how many steps have been counted, but will reset each time the z-pulse is passed.  The z-pulse is the encoder zero point, so it will reset every time the encoder does one revolution. Based on this information, you will know if the encoder works if the correct amount of steps per revolution are counted each time you jog the axis the distance of the ball screw pitch length.  If the numbers do not match up, you have a problem.


Motor Brake

Corrective Action:

Reseat the the connection for connectors P79 or P78 [1] on the I/O PCB.

Measure the voltage across the red and black cables.

Press [EMERGENCY STOP]. There should be no voltage.

Press [RESET] to clear the alarms. The voltage should be between 20-30 VDC.

Examine the connection at the motor's brake [2] and power connectors [3] for contamination. Reseat the connections.

If no voltage is present, refer to:
