![]() We have applied several hundred SP drives in servo rotary and linear motor applications and I have generally been pretty happy with the phase offset feature and reliability of results. I have found that poor commutation offset calculations are most frequently associated with 1 or more of the following causes.ġ.) Motor loaded when trying to determine phase offset.Ģ.) Severe noise on the quadrature encoder signals resulting in the drive losing track of the rotor position and commutation phase angle accuracy decaying over time (requires a power cycle on the drive to initiate re-alignment)ģ.) Current limit set too low in the drive such that it cannot develop enough torque to control open loop rotor position and gain an accurate phase offset reading. It is imperative that you have the correct current rating associated with the motor nameplate programmed into the drive and appropriate current limits set as well. 31.Īre you doing control via the actual Unidrive speed/position loops, or are you doing it via torque control and an external position/speed controller?Īre you certain that the motor is completely unloaded when conducting the phase test?Īlso, you don't state whether you are using resolver feedback or hall (U,V,W) encoder tracks. They have always been the best phone support. Well the file that it claims is missing is in the CH files. If that doesn't fix the issue then idk my guy. I have my game installed in my Documents folder and it works just fine. The game may not have permission to access other files in that directory. If you can't get them, then you can try my local support # for my distributor. Maybe try installing in a different folder, or starting it with administrator privileges. And their tech support has always been helpful for me.ĭid you try their Minn # 95, and I don't know if they still do support out of Grand Island NY, but they were always helpful too (if you can find that phone #). I have had very good luck with the Classic Unidrives, and have used a few Unidrive SPs with very good success. Video of the Day Step 2 Test the DVD player front panel buttons with a DVD inserted. Remove the remote's batteries and replace them to see if this restores the remote. By far the most common cause of a remote that loses functionality is that the batteries have simply gone dead. If it still doesn't work after this then? Step 1 Replace the batteries in the remote. (NOTE: not swap two phases but rotate all three). An easy fix�would be to rotate all three phases until it works. I have experienced what you have on other brands of motors and drives, I used an o-scope to determine what was wired wrong. wrong hall orientation to the motor phase orientation. wont into newcastle things freedating profiles. It sounds like it is not phasing properly, which since it happens on many drives and motors, I would assume that the halls in the servo are not connected properly i.e. vip pua perfect japan clubs military ottawa eharmony 50 jobs time chemistry com. Not sure of what motor your are using, but I have to assume it is one of the Emerson/CT Servo motors with Hall Sensors.
