Spindle and Inverter connection

[johnketta]

Hi,

I'm converting my router to Masso and following all documentation and videos I could setup all functions but not the spindle.

I have a spindle GDZ-80, 2.2Kw, 400Hz, 24'000 rpm and the inverter is a Fuling D130B002.2L2DK and I don't find how to connect this to Masso G3 as I don't find where is FWD and REV.

I followed the videos I found but there are not the sames connectors to this inverter.

Maybe some one has already experience with this inverter or somebody can guide me to achieve the installation.

Many thanks in advance.

John

John,

Wiring is quite simple, as per diagram 2.3

• MASSO - VFD
  
• pin 1 -> VI
  
• pin 5 -> FWD
  
• pin 7 -> REW
  
• pin 4 -> DCM
  
• pin 6 -> DCM
  
• -ve -> DCM
  
• -ve -> ACM
  
• +ve -> EV
  

If the FWD & REV commands don't work try reversing pin 4-5 and 6-7.

Parameter settings

• F1- 38 -> 0000 External Control Terminal Configuration
  
• F1- 01 -> 0001 Operating Frequency Source Select
  
• F1- 48 -> 10.0 Analog Input Setting for Output Frequency Range
  

This should get you going.

Regards,

Arie.

I added the information you require in my build post and deff had to reverse a couple of wires.

I am on phone but it is in build section under Chinese 1212 router build

I just remembered there are dip switches on the PCB that might need changing also, I took photos and they are in the post, but the photos need to be looked at in detail. There is a PNP/NPN switch and also 3 switches for enabling the 10v mode

the link to my build it has furlong inverter programming information, it seems as though your model is different but should be helpful

Thank you to Arie and Steve, it works now.

But I think seriously to change my VFD and Spindle to a recent one.

Do you have any tips.

Regards

John

I actually think the furlong inverter is actually a quality product, Mine has been very robust but i am running the 300 series with a generic water cooled 3.2kw spindle. it also has two modes of operation I am not sure if yours does I actually need to change to the other mode which will only work with one motor and uses a feed back loop to give constant torque allowing for slower revolutions at high torque, once the mode is set it tests the motor to calibrate the feedback loop. ATM i can get 700 to 24000 rpm but think i may get lower rpm for drilling but the main thing is the torque is constant. If you do really want to change I would suggest one of the models supported by Masso

I actually think it wouldn't take much for Masso to support the furlong inverter range of vfd given the information available

As for the spindle I regret not getting an air cooled spindle as having to maintain the fluids and pumping water into the spindle really worries me actually if anyone can suggest a better pump than a fountain pump that generates more noise than the machine in action it would be great. I build PC's with water cooling and have seen that tech used on spindle motors with the radiator pump and water storage mounted on the z axis head so a closed loop system with radiator and fans I might give that a try as having a big storage container full of coolant and a pump that can barely pump the water through the spindle is actually my biggest worry with my machine

Am so glad you managed to get yours working as I had to do all the research to get mine operating. Btw it is a technology I am not used to using my electronics experience is Telecom's, AV, and embedded design this is more industrial than I am used to. Also I have spent the last 10 years in 2pac for cabinet makers but have gleamed a lot of knowledge from the cabinet making side of the industry

I hope you really get to enjoy the benefits of the Masso product..

Cheers Steve

Steve,

I actually think it wouldn't take much for Masso to support the furlong inverter range of vfd given the information available

MASSO supports all VFDs that accept 0-10v speed control and FWD & REV signals, so the Furlong Inverter range is supported.

If you are referring to being listed in the documentation, that will happen if there is a demand for it by the users. It takes time and effort (which is finite) to write / draw each VFD type, so those that are listed is the result of lots of users asking for assistance for that VFD. Even the VFD that is on the BMS's router supplied by 3DTEK, who is a reseller of MASSO, isn't listed.

Regards,

Arie.

Totally understand that why i suggested if John really should upgrade vfd supported by Masso as a good option. But I still consider the furlong inverter to be a quality product

I am very happy with the furlong vfd BTW what is your opinion regarding Speed sensor-less vector
control (SVC) and V/F control. mine is set to V/F control but my research has shown it more for multiple motor drive and not cnc spindle operation

Many thanks Arie

Steve
