I recently acquired my parker servo motors (SM233-AE) and GV-L3E drives. I have succeeded in updating the O/S on the drives to the latest and am able to download the default profiles to the drives from the wizard. Torque mode (DMODE2) seems to work fine as well as Torque Mode Tuning (DMODE15) but when I try Velocity mode which is what I need for my CNC machine to use, it doesn't respond properly.
In this case the drive just spins at a fairly rapid rate in a clockwise direction. Both DMODE4 and DMODE16 do this.
Now I am not using a 6K controller. I just have the Drive and Motor hooked up with the default yellow cables and then I have a 50-pin breakout board so I can access each pin as needed. Right now all I have is PINS 1 & 2 going to a toggle switch so I can enable/disable the drive. I also have wires coming off of PINS 23 & 24 which is supposed to let me test +/- 10v for analog control.
In other servo motors normally you can test the velocity mode with the resolver/encoder feedback disconnected, and just apply some voltage between the input pins to produce motion in one direction or the other based upon input polarity. Increasing the voltage makes it go faster of course.
However in my case these motors just run fast in 1 direction and don't respond at all to changes on pins 23 & 24. HELP!!! Has anyone played with this who would be willing to help me? Do I need to have other pins connected up? I'm stumped...
