I'm in need of a mentor for the HIT 8S lathes who is located in Texas who is willing to show me the basics of the Siemens controls.



Thanks

Just replied to a question on troubleshooting the Siemens Simodrive E/R module on a Hyundai HiT 8S so I thought I'd post it here in case anyone else can make use of it, or add any more info to help out.

Hi J.D.,

Here's what I have for the LED's on the E/R module:

Top left LED : RED 15V supply fault
Top right LED : RED 5V supply fault
Middle left LED : GREEN Power on (should be lit)
Middle right LED : YELLOW DC link OK
Bottom left LED : RED 3-Phase supply fault
Bottom right LED : RED DC link overvoltage

There are a ridiculous amount of manuals for these units so it can take a lot of time to find what you're looking for. It sounds more likely that the spindle power unit could be failing. Do any of the red LEDs light on the E/R module? If it's the E/R module then you should be able to measure it with a meter on DC volts on the busbars across the front of the system - just hook up your meter leads securely and then power on and slowly increase the spindle speed and see if the bus voltage drops any when it faults out. It's hard to isolate the problem without having a good system to swap modules, as if a servo or spindle power unit isn't switching correctly it can also pull down the DC bus. You should also check the AC 3 phase power coming into the system if the DC bus is being pulled down, as you could have a bad mains connection or insufficient supply capacity that would cause the voltage to drop under higher loads.

*** Of course I have to put a disclaimer in here so I don't get sued if someone fries themselves - the DC bus is around 650VDC, can easily kill someone and can hold a charge for a few minutes so make sure you are qualified to work with this high voltage ***

Hope this helps. If you do find you have a faulty module, we should be able to repair it for you. We offer free evaluations and no fix no fee service. Just call 704 889-2404 or ship to

Hi I recently purchased a Hyundai HiT 8s with a simodrive 611. I suspect the E/R module is getting week? Can you tell me what the 6 lights on it mean they are labeled spp, 5v (I assume this one is 5 volts), ext, unit, ~, and Udc. If I command a spindle speed above 1700 rpm the control gives me 3 alarms 1 of which says "servo not ready" the other 2 are machine E-stops.
Thanks in advance.
J.D.
