Thank you for your reply, here are some answers:
Spindle speed is achieved correctly, although during the last times I noticed it dropped a little from the setting, what I mean is if usually it was always within 1-2% now it is 2-4% deviation from setting value. It changes tools perfectly too.
I had no idea there is another encoder in the motor - my model is the 80-8000 direct drive without gear.
So now I know what is F-602 that is dispalyed on the controller when the cycle fails and drives are switched off - I was confused when I looked in the manual at the controller's error codes explanations. Except this everything is ok on the comtroller's display.
No, I didn't tried regular tapping - I usually work with rigid only, and the option exists, I used it many times and works great.
I will try the maintenace page today and see what happens.
About the error probable solutions as described in the manual - I located the "dynamic brake resistor" or I hope I did, it is behind the spindle controller, a large rectangular white power resistor, also will check it today.
What is the "dynamic braking time parameter"?, I assume it is set in the spindle's controller but the manual says nothing about it.
One thing I don't understand, or maybe confusing, but when a tool is changed the spindle rotates slowly to orient the tool holder and brakes - and this works, isn't it supposed to be the same operation?
I will resume testing today, I had another problem, while opening the spindle's column covers I am not sure how it happened but I found the tool clamped limit switch broken - today I am getting a new one and I will resume testing.  |
