Haas Spindle Drive Fault and the DS30911/21/2016Haas Automation makes many different models of machining centers for a multitude of different purposes. For the purposes of this article, we will discuss a select few models. VF-1, VF-2, VF-3, VF-4, HS-1, HL-1, and HL-1h. These models of machining centers typically use the Magnetek DS309 AC motor controller as a spindle drive. One of the most common faults related to the spindle drive is CNC Alarm 123. This is a general fault meaning there is a spindle drive failure, spindle motor failure, or regen load failure. This condition can be caused by a shorted motor. Another possibility for the fault is the DS309 spindle drive failure. Drive conditions such as drive overcurrent, drive overvoltage, or drive undervoltage can cause it. Overvoltage and undervoltage of the DC bus are also reported by alarm 119 and alarm 160 respectively. Further still, the fault can be caused by a shorted or open regen load. When you get the alarm 123 on your Haas machining center, out of the three possibilities mentioned, the most common problem is going to be with the spindle drive itself. You should then inspect the drive itself for signs that it may have failed. Check the drive to see if the fan is running. If not the drive may be overheating. You should also take a look at the drive display to see what fault code may be indicated. One issue that is very common with the Magnetek DS309 in the Haas machines is no power indication at all. If the drive is dead, it most likely has a bad internal power supply board.Once you have determined through your troubleshooting that the spindle drive itself is indeed the cause of the machine alarm or alarms, the issue then at that point becomes a question of repair to the existing drive vs replacement with a different drive. Replacement is usually a more costly option. It typically involves a technician or representative from Haas making a service call to your location to do the installation. Repair to the existing drive is usually a more economical way to go. It saves the time and expense of having factory service personnel schedule an appointment and come out on site. With a little time and patience, a minimally trained individual can disconnect and label the power and control wiring to the drive one wire at a time. You may even want to take a few photos of the terminals and wiring before you get started to be sure it looks the same when you’re replacing the drive. After the drive is removed from the machine, the process becomes a piece of cake. Now you just call on a qualified repair shop that has lots of experience with the Haas spindle drive repairs to take care of fixing it and getting it back to you ready to reinstall into the machine and start making product again. I can think of one repair company that really fits the bill. Call 800-732-4695 to reach the experts! Back To Blog
