Help please !!! Servo configuration with stepconf.

I hope you get that sorted out... as for which PLC you use that is something only you can figure out. I use a lot of PLC's AB, Panasonic, AutomationDirect etc day to day and sometimes it makes sense to use them and sometimes it makes sense to use Classicladder and sometimes it makes sense to just use a relay and a timer... just depends on the job at hand.

Keep us posted on your progress.

True. It all depends on situation and type of job. Also we should have to have a system of which you can get support from others. OR face it alone as I am already facing with my drives. Still waiting for suppliers reply about how to eliminate "torque overload" error.

I have the PDF manual file with the parameters which is 2.8mb. But I don't know how to upload it.

I uploaded the manual.

John ! I really appreciate your help.

Regarding the parameter setting in 4.8.3, I had a look at it but didn't realize it's importance. Is it really important ? Then I will go through this chapter.

Actually I pushed my whole energy at power source combination. Because I cant jog the motor alone with driver without linking it to breakout board to make servo enabled. The breakout board get power from PC usb which I think supply 5v or 3.3v while driver needs 12v-24v.

I set the mode type properly at every type of run like jog and position step/dir mode but really missed this one.

That means if motor moves little bit with jog command and from pc step/dir command then there is nothing to worry about power source ? I have concern about it because at page 35 in position control schematic there is mentioned 12-24v power supply to vcccom pin.

I have solved the issue and now motor is running smooth. Some enhancement still left in my machine to tune it with load. But before my Mesa cards arrives, I will try to hook it with my basic breakout board and with step/dir commands configured with stepconf wizard.

The cause of my problem was that I gave servo enable power through my breakout board which was showing that it's enabling the servo while it wasn't supplying enough power. Today I removed servo enable wire from breakout board and supplied the power from external 12v source to servo enable driver input port and it started spinning the motor smoothly. Now it's time to tune as you all suggested.

I tried to move an empty motor with stepconf jog and it runs smooth from there as well. But it lacks speed. I can't manage to increase the speed with stepconf but I am sure that I can manage to do it with drive's internal settings. But is it recommended to do this with open loop configuration ?
