Hello Guys! I have couple of questions about tuning an ab servo motor. -Actually what does the drive or plc doing when I launch a servo auto tuning? - What are the little boxes like position error integrator ? There are checkmarks in fornt of the lines. Can I choose the methode or something? I mean its not "auto" ? Why it is auto then ? - Can someone send me some basic literature where they explain me what these stuff acutally meaning ? - What is the hook up test what for is good ? -When you are doing a servo auto tune what are the parameters that you are monitoring and why ? -I should do the auto without or with load ? Whats the difference ? I know there are so many question I would be so grateful if someone could help me with these answears, or even just with one. Thanks again.
Hell PLC World! I have been trying for several weeks in my spare time at work to tune an Allen Bradley Servo Motor. Below is the list of hardware I am currently using: - CompactLogix Motion Controller (1780-L33ERM) - Kinetix 350 Driver (2097-V34PR5-LM) - MPL Series Rotary Servo Motor (MPL-B310P-MJ74AA) I have been using RSLogix5000 for testing and I plan to use it to develop a simple conveyor type program later. I have tried a list of things which will be below, but to no avail, I cannot simply jog the motor for any period of time without triggering a position, velocity or bus voltage error. I have tried changing the motor, driver and feedback cable to no avail. Here is the process I have used: 1) Add the hardware to RSLogix5000 (PLC, Driver and Motor) 2) Configure the motor 3) Run the hookup test. This works flawlessly. The motor will slowly turn independently on the feedback test for as many revolutions as I input. This is what makes me think I am doing something wrong in the tuning process. 4) Run autotune process with the velocity, acceleration and jerk set well below the limits of the hardware. 5) Attempt manually control motion 6) Recieve error I have tried changing the input from trapezoidal to S-Curve, changed velocity and position limits, manually tuned velocity gains in a myriad of configurations. I have swapped legs on the 3 phase input (which made matters worse). I suppose it is possible that multiple pieces of hardware are faulty because this equipment was previously used, but I still cannot wrap my head around why the hookup test would work so flawlessly, yet I cannot just get the servo to rotate at an equivalently low speed. If anyone recognizes my mistake, I would be eternally grateful. I am an intern studying control systems in graduate school and as popular as AB is, I would sure like to get some experience with it. Thanks in advance!
Hello all, I was asked to check if there is a PID real - time software which automatically calculates PID loops parameters and update the PLC registers or HMI ( by OPC server etc.) when the process is working and "breathing". REAL-TIME. Not PID simulator or PID tuner based on measured data, but a software that will calculate and update the PID parameters in real time while maintaning several PID loops simultaneously. Are there any suggestions? Thank you, Olesia
