    How are things working out after these retrofits? We have 2 QT-10's and one of them has the same intermittent problem they all seem to have.

    Hi Steve, The retrofit is working good. I haven't run the machine much as of yet, but I do power it on from time to time and play with it a bit. For me it is one of those machines that mostly sits around and gets used once in a while.

    I haven't had any problems with it, no alarms, nothing bad has happened. The machine just does what it is supposed to do. Overall the spin up and spin down time of the spindle is slightly slower than what it used to be, but other than that it seems to be working out good.

    PS I have never tried tapping with it, so I can't tell you if that part has been affected or not, but over all I am extremely happy with the retrofit and recommend it. With the support of the people around CNCZone and Toshiba Drive technical support it was really pretty easy now that I look back on it.

    I wish you the best of luck and if you decide to do the retrofit, let us know how it goes. I still have fresh notes if you should run into issues with it.

    PSS I also sold my old Mazak drive back to Mazak. They paid for shipping and gave me $200 for it. It was broken, I didn't need it and it covered part of the cost of the new Toshiba drive which for me was a win win.

    Hi,

    I have MAZAK VQC 20/40B with Mazatrol M-2. I have problem with its spindle drive unit (FR-SX). Is there any way to repleace any another driver. Some guys here says there is no way because this driver has orientation point on it to change tools from magazine. So I am confused. Sorry for my bad english and thanks for your help.

    Hello,
    I have planned to change my fr-sx drive for this VF s11 toshiba drive and I have one question, Can you still program threads using this one?
    Thanks

    Hi Jolulank, I never used the tapping feature on the turning center so I don't know for certain. From what I remember though I think you should be able to still do tapping. The encoder feedback for the Spindle went straight back to the NC so the VFD drive itself didn't have any encoder info going through it for tapping. I believe the Z axis would sync to encoder RPM and the Spindle would stay the same speed. I traded up the machine so I don't have it anymore unfortunately to test.

    Hello again and thanks for the help, it seems i need more assistance.
    I already installed the toshiba drive but there are two things that does not seem right. I set the parameters as indicated, I made the connections too.
    When I start the drive the motor seems like it stutters, I checked the out voltage and suddenly drops and comes back, so it seems reasonable that it happens. Another problem is that despite UL and FH parameters set right I cannot get past 60 rpms.
    If I command forward or reverse it does the same thing, stuttering and max 60 rpms.
    Please help!!!

    Thank you

    jolulank

    When I was initially setting my drive parameters to the motor I had some issues just like you are describing. if I remember right it was something to do with the ramp up speed or some other "more advanced" parameter that really shouldn't be adjusted until the basic first parameter settings work to at least get you spinning. Toshiba has great phone support. I would suggest picking up the phone and talking through the basic parameters with one of their technical representatives. Once you get the motor spinning you can start adjusting other things once at a time. You might even want to reset the drive to the factory defaults and just try it to see what happens before adjusting anything. There are only about 3 or 4 parameters that need to be set to get you spinning. After that it is all tuning the drive to do exactly what you want.

    When you call Toshiba make sure you have your motor numbers. i.e. the numbers on the motor nameplate like 30min kW Rating, Voltage, # of poles, 2 or 3 phase, etc.

    Start at the very basic stuff and go from there. Good luck and let us know what you find out.

    Hey guys, I know this is an old thread but I'm in the process of installing a new drive in my QT-20 and have a couple questions I'm hoping you can help with.

    1) Is the speed input 0-10V or 4-20mA?
    2) How do you hook up the cooling fan on the spindle motor? Seems like it needs 200V 1ph at 0.2A based on the motor nameplate (see pic)
    3) I'm missing the leads ARST1 (19) and ARST2 (20) for alarm reset but I have leads (47) and (48) which aren't listed in the manual. Do you think it's possible to test these leads somehow to see if they are the alarm reset leads?
    4) On CON 3 there is a speed detect wire VR0 (16) and COM (20). Should this be used to operate the VR0 relay that was jumpered earlier in this thread?

    Thanks for any help you can provide.

    Matt.

    Just a heads up, I got this going a while ago. Forgot to post the results and I can't remember what the details were but it worked great.

    Helo Matt
    I'm trying to replace old freqrol on my qt8 with new Yaskawa v1000 drive. How did you solve problem with connecting blower motor?
