PCB Auxiliary (AUX) Load - Installation

  1. Servo Amplifier
  2. Smart Servo Amplifier
  3. Smart Servo Amplifier with AUX Load

Do this procedure to install the AUX load [3] when you install a Smart Servo Amplifier [2]. The replacement amplifier must have the same amp rating as the servo amplifier [1] that you remove. You must install the AUX load [3] on the replacement Smart Servo Amplifier [2] if you have these two conditions:

  • The machine has only two servo amplifiers [1].
  • You must replace only one of the servo amplifiers [1] with a Smart Servo Amplifier [2].
note: In other words, if after the installation the machine has only one servo amplifier [1], the replacement Smart Servo Amplifier must have the AUX load [3].
Safety Notes
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.

Do these steps before you do work in the machine or in the control cabinet:
  • Set the main circuit breaker to the OFF position.
  • Use an approved lock with an approved safety tag. Always follow lock-out procedures in accordance to local government rules.
  • After turning off the machine, wait at least 5 minutes before working in the control cabinet, to allow power to dissipate. Wait for the voltage indicator LED on the vector drive to go off completely.
  • Always turn off the main air supply when you work on any part of the pneumatic system.
  • Make sure to rest the spindle head on a block of wood when work is done on a vertical axis. This will prevent any unintended movement that could result in the axis falling.
  • Never alter any safety circuits on the machine.
You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes. Serious damage to the machine components can result in costly repairs. The service technicians at your Haas Factory Outlet (HFO) have the training and experience, and are certified to do these tasks safely and correctly. The repair and service work performed by your HFO is protected with a limited warranty.
danger: 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.
