Can you describe the problem and the solution for the next person to come along with the same drive?
Sure,
There are 5 inputs and 1 E-STOP with this Fanuc Spindle drive. A06B-6044-H103.
As shown in the attached schematics:
All use gnd as input.
You need 4 inputs to place the drive in a mode to receive analog input (VCMD) from mesa 7i77 card.
Estop has to be closed,
ToolUnclamp has to be close. The drive will take care of disabling the spindle from turning.
SP Forward or SP Reverse has to be closed. Tells drive which direction to turn the spindle.
Low Gear needs to be closed also. Even though this spindle has only one gear the drive is looking for this signal. Contrary to what the docs were saying with a one gear spindle, you need this signal.
Orientation - You need this input when you are doing a tool change.
I haven't got the reverse spindle to happen yet. Pete said I will have to use ABS comp cause I told him that the drive needs 0-10v forward and 0-10v reverse.
The docs shows it that way and on a few other pages it shows -10 to +10 V, so I haven't figured this out yet. Will work on this in the next few days.
I tested and adjusted the orientation and all i need to do is close the orientation input to gnd, and the drive slows the spindle and stops it in the correct position
to perform a tool change.
Also you get 5 dry contact outputs for alarm, orientation completed, spindle speed signals.
I will need to know when the orientation is finished when doing a tool change.
Also, I have a physical rpm meter and load meter that is working also. This is an analog out signal.
There is the possibility to use an external speed override pot as you can see in the drawings.... OVR1 and OVR2. I will not need it as I will use the axis slider for that.
