RTA PAVIA SDC 05 32-65VDC Stepper Driver Wiring Connection Diagram

[guy2b1]

Please help I found this industrial stepper driver RTA PAVIA SDC 05 32-65VDC and would like to use it on my CNC project, anyone who has the product technical documentation of this Stepper Driver? Because I already connected it to my printer port using Mach3 but I notice its not rotating in any direction but the torque is very strong I cannot rotate it manually by hand. Im not sure about the wire color assignments. When my power supply is turned off my stepper motor can easily manually rotate by hand but when I turn on the power supply its very stiff and strong that I cannot rotate it manually by hand. I am using 48Volts 6Ampls power supply to power 3 stepper driver of RTA PAVIA SDC 05 model and 3 stepper motors. Please help

Hi, I'm also want to running this Stepper Driver. Follow this thread.

Hope this helps with your drives as it is very similar to my rta drives.
when you supply power to your motors they should lock up until your drives move them.(in other words you cant move them by hand)
I use the sherline 1/2 pulse mode setting to drive my motors its the only setting that works on my drives.
Also some interface boards wont run these drives as i have found out ,i use a optocoupler for my xyz outputs.

There is no SDC series. Closly there is NDC series, my driver almost like that.

This is helping.

how about the 6 blue switches labeled 1 to 6 in the driver, is it for microstepping settings? how to set and use it?

This should knock it on the head !!!

Thank you mkc2, presently im using this drive using 60Volts 12Amps Power Supply and I need to adjust the setting because my stepper motors is kinda hot to hold or touch by hand

Why my input driver is low resistance? Pin Step in + and step in - resistance less than 10 ohm. Optoisolator can't give signal there.

I have 2 pairs of these RTA Pavia Stepper Drivers with Motors and plan to connect it to a single pin assignment in printer port using Mach3 so that it will rotate in the same direction. Lets say im using Mach3, in printer port I assign it to pin 2 and 3 for step and direction then pin 18. So I connecto 2 stepper motors with 2 stepper drivers to pin 2,3 and 18 for ground. When I run it only 1 stepper motor is working. What seems to be the problem?
