    No, it may be a cluge though. The yellow wires went to the micro-switch on the end of the adjustable pressure switch but it does not work so I bypassed it. Actually replaced it the way it was. I had...

    A Motor Z Fault, BUT

    The A motor is not connected and the A axis is turned off, '91 VF-1. Usually happens during a tool change. I have added parts to the receiver board to use a differential line instead of the TTL...

    I have a masters in aero but do not have a flow code so I designed the ports for a new BSA head by drawing it in CAD then 3D printing and testing on a flow bench.
    It is not the best shape since it...

    The encoders for the XYZ go into the receiver board which has AM26LS32 chips which connect to the HCTL-2016 quadrature decoder/counters but the A axis encoder goes straight into the HCTL-2016 which...

    My '91 VF-1 has a receiver board mounted over the MOCON board with AM26LS32 Quad RS422 Receiver to three state output chips. So the MOCON Board has TTL inputs. I rewired mine to use RS-422 for the A...

    I have a '95 HRT cable 17 pin. The wiring on this cable is:
    17Pin HRT
    A E8
    B E6
    C E9
    D H1
    G GND
    H M2
    J M1

    Resolvers are analog output but it still is converted to digital for the computer. CUI makes capacitance encoders which are also analog output but converted to digital within the encoder.

    I prototype new design parts with a 3D printer first to check assembly and fit to existing parts before machining. It saves a lot of time and material when looking to see if parts can be assembled...

    Go into the Control Panel, System, Device Manager, Ports. Go to Properties, Port Settings, Advanced. Uncheck the box for Use FIFO Buffers and set the buffer values to 1.

    To go from a TTL encoder to a differential receiver you need a AM26LS31C Quadruple Differential Line Driver. I have the Renco RM21 PDF that gives the wiring but it is too large to attach.
  15. The difference is obvious, a TTL encoder has just...

    The difference is obvious, a TTL encoder has just A,B,I outputs, a differential has A, /A, B, /B, I, /I.

    Here is a listing of the 17 pin and 14 pin connections. No need for the Motif P9 connections. Read as follows for the encoder:

    From the VF Service Manual - 96-7045, from Figure 6-9 you can see the unclamp switch is below the clamp switch. The air piston moves down and pushes on the drawbar to release the balls holding the...

    On holiday at the moment so no access to my machine or notes. You can turn off (disable) the axis servos through the parameters. Check the LEDs on the motherboard go through the correct sequence.

    Thanks but this is way older than a Coldfire, a '91. I have rebuilt a few boards, such as the servo and power monitor, added a push-pull chip to the receiver for a 4th axis and added more memory so I...

    Alarm #112 Interrupt fault

    Anyone ever have this? The manual just says "Call your dealer, electronics fault". Right, they probably want to sell me a computer that costs four times what the machine is worth.

    I do not know if a '97 differs from a '96 but the manual says the encoder Z channel signal must occur between 1/8 and 7/8 revolution from the HOME switch release or a 165/166/167/168 error occurs....

    Well, lucky you do not have an earlier machine where the regen resistor is located below the servo boards which are below the three board computer stack.

    I found putting carnuba wax on the tool holder taper works well to keep them from sticking in the spindle.
    You can try selling them but BT40 are far less common here than CAT40 so there is not much...
