How to find the old Braking Resistor
Where is the braking resistor on the old drive? I am mostly up and running, but my deceleration time is set very slow until the old drive's braking resistor can be hooked up to the new Toshiba drive. Here are some pictures of the old drive, can anyone direct me on where the braking resistor is in all this? I assume some things have to be unhooked and I will end up with just two fairly big wires to hook up to the Toshiba. Not sure what I am looking at though and would like your help.
Thank You,
Benjamin Barch

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

Re: Replacing a freqrol FRSX-2-11-K
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

Re: Replacing a freqrol FRSX-2-11-K
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.

Re: Replacing a freqrol FRSX-2-11-K
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.

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