Hello all,

I have two Bridgeport Interact II vertical mills. We have been running linuxcnc on the newer (1994) machine for almost two years. I am in the process of retrofitting the second (older) of the two. The spindle motor was working fine when the TNC controller finally quit on this machine. The CONTROL TECHNIQUES 6P4Q-7.5 spindle drive on this had issues when it got hot so I want to replace it.

My question for this forum is this: Can you help me decide whether I should purchase a (used) DC speed controller and keep the existing spindle motor (specs below) or should I rip it all out and put a 3ph motor and a VFD in it? I am perfectly comfortable with the 3ph/AC motors and controls, DC motor controls, not so much.

Parker 514C-32-00-00-00 controllers are available for $700-$900 on ebay. Can anyone help me determine if this Parker controller will work with my spindle motor?

Is there a better fit?

Thanks in advance!

Saat ini saya sedang mengalami kesusahan dengan program visual studio saya dan juga beberapa inverter motor dan PLC saya
Saat ini komunikasi saya menggunakan modbus pool dengan es 485 port yang saya punya,
Saat motor tidak berjalan semua baik" saja,namun saat motor sedang di jalankan,seakan program dari PLC tidak memberikan respon kepada visual studio saya yang menyebabkan ada tulisan *not respon from modbus slave*
