Hello,
          I have two pairs of Suqiang SN2000 Serial Servo motor drive and motor. I have a plan to change my conventional lathe machine to CNC machine with this driver and motor. I want to change this with Mach3 cnc control software. So, I want to know that can I use this drive and Mach3 software? Mach3 Software generates the "Step" and "Direction" signal to drive the servo motor. So, is Suqiang Drive accpet "Step" and "Driection" signal? I have no experience about servo
drive. This is my first experience. Please inform me can I use or not this drive with Mach3 software. Please tell me which pins that I connect for step and direction if it is possible. I am looking forward
your reply. Thank.....

The following link is for this SERVO DRIVER-SN2000 manual.

Please tell me connection diagram between Parallel port and drive if you are OK. I hope someone will help me.

Hello,
        I have Suqiang SN2000 Serial Servo Motor Drives and Servo Motor. I want to know about this drive. Can I use this drive with Mach3 Controller software? This drive link is:

         http://www.sqsk.cn/en/productshow.asp-showid=73.html

       Please see this page and reply my question. I don't know about motor drive control. I want to know about this drive can be work with step and direction control that generated from Mach3 software. I hope someone help my difficuilty. I also wanted to know the wiring connection if I can use this drive with Mach3. Thank....

FAQs / About AC and DC Servo Drive (CNC conversion)
« on: August 29, 2009, 12:28:50 PM »
Hi Sir
           I want to ask a few question. I want to change my old Anilam 3000M CNC machine to Mach3 control machine. I want to use products from Machmotion Mill kits Teco. My anilam has DC brush Servo Motor with rated torque 31 inlb (3.5 Nm). So I consider I will use Teco 30 in/LB Class AC Servo Motor & Drive. The rated torque from machmotion is 30 in/lb Class (3.389 Newton meters) (480.0 oz/lb). So, I think this motor and drive is suitable for me. But I find the specification for this motor from Teco home site. The rated torque is different from machmotion site. The rated torque is only 2.391 Nm. The max torque is the same from both sites. The max torque is 63.4 in/lb (7.164 Newton meters) (1014 oz/lb). Can I use this motor for my CNC machine. I asked machmotion this problem. They reply like this:
        
        "That is a typo on the web site, the motor is rated at 2.391 Nm, but we call it a 30 inlb class because it's performance is much greater than the old DC brush motors.  If you have DC brush motors rated at 3.3 Nm continuous I would replace that with an AC brushless motor rated at 2.3 Nm because the max torque rating is normally much higher on the brushless motors.  The max torque on the 30 inlb class motor is 7.1 Nm which is 62.8 inlb."

         So, I want to know about the different between AC and DC Servo Motor. Is it really AC motor have greater performance than DC? Moreover, can I use this motor for my machine. I can't use larger motor and drive because of price. Please explain and answer my question. I am worried about this problem because I am a newbie in CNC conversion. I worry that I cannot use this motor with my machine after I have already bought. Thank......
