    Default Cincinnati Arrow 1000 ATC Actuator Reversed

    Hello all! Long time lurker, first time poster. I want to give a HUGE thanks to maver1ck, BBMNet, meckardt55, coop31, and the many others here that have posted some excellent information here and got me started on my Cincinnati journey.

    I just got an Arrow 1000 with A2100 control and started running through functions tests but the tool changer carousel refuses to move to the spindle position. Upon mechanical jog to the spindle position, it moves about and inch to the right and then chunks to a stop. I opened up the ATC panel and it seems like my "scissor?" motor actuator arm is moving up when I am trying to move to the spindle position and bottoms out at the top of the slot. Based on the slot geometry, it appears that the arm should be moving CCW or down to move the carousel into the spindle position. Is my actuator motor moving in reverse? I popped the back of the motor cover off and it looks to be 3 phase. I come from DC world and I am not very confident with 3 phase systems. I am assuming there are two different contactors in the main control cabinet somewhere. I have paged through the electronics schematic but am still learning how to navigate it, I am more used to automotive wiring diagrams.

    Can I just swap two of the 3-phase wires on the actuator motor? Or is it more likely that the output signals to the contactors got swapped at some point?

    ...is the coolant pump running backwards too? maybe the Input wiring to the machine is wrong.

    Oooo good point machinehop! I haven't wired up the coolant pump yet but I will definitely swap the leads around on the input power and see if that does the trick.

    I am a bit nervous to run the coolant pump, this machine was used for wood only for a number of years and the entire coolant tank is covered in rust. I have concerns about flooding my bed and rails with liquefied rust and possibly blowing the seals on the TSC and washing the spindle with high pressure coolant. What do you guys think?

    ...or maybe try M3 to see if the spindle is rotating in the correct direction.

    ...Great and your welcome glad to help. Love those easy repairs. Now that the machine is up and running might be a good time to Backup all the control settings. Write down or download MTB Parameters etc... If, I remember correctly the A2100 has a HDD that will fail at some point in its life and you should make a Backup Image if possible asap. Look in your manuals may help explain the process or someone here in the cnczone should know more about Backup.

    Enjoy,
    DJ

    DJ,
    Thanks for the tips! The previous owners had already converted to SSD before I bought it and gave me a box with 2 or 3 backups on spinny drives! They were very knowledgeable in the Cinci world, but they were exiting so this was their last one. Luckily, the machine came with literally TONS of spares. Servos, ballscrews, motor drives. I probably have enough to build a whole new machine from scratch (minus the castings).

    Quite a dusty machine! The second pic is after about 12 hours with simple green getting some of the caked on sawdust off the insides of the machine.
