  1. Hi All, I am doing an application that use servo motor to feed plastic film to a target length (set by operator), and it need to stop immediately if marker sensor is ON. This application is control by Omron CP1E PLC. It will feed plastic film in 500-1000mm/s depends on the target length set by operator. It is require to stop immediately if the servo feed length more than 90% of the target length and the marker sensor is ON. However, is there any possibility for the servo to stop immediately once the condition is meet? As I am using PLS2(887) to feed with target length, and INI(880) to stop immediately, however, it cannot get the desired result as servo not able to stop immediately after marker sensor is ON, I am not sure is because of the PLC scan time, or servo need time to deceleration (deceleration rate assigned to #FFFF). Appreciate anyone able to assist on this. Thank you.
  2. CC-Link IE + C#

    We have a controller written in C# and need to integrate a servo.  We are looking at the Mitsubishi servo MR-J4 line.  Unfortunately it doesn't support Modbus TCP but does have the CC-Link IE protocol.  Does anybody know if it is possible to talk to CC-Link IE via C#?   I'm having a helluva time trying to find an answer.  I see some thing about Seamless Message Protocol (SLMP) and CC-Link but the info is somewhat sporadic.  Any advice is much appreciated as I've never worked with the Mitsubishi product line (but interested in their PLCs).
  3.  Hi all. I have a question about how to set up the motor in rotary mode. My application will be a basic rotary table driven by a servo motor without gearbox between. So, in my servo drive axis settings, I select the motor as a rotary mode. then I defined the maximum position setting value for 360 degrees, and minimum to 0. So far so good. But the problem comes when I want to make an absolute move using the mc_moveAbsolute to move 360 degrees. Whit this settings the error "target position settings out of range " will come up. So, what is the solution to rotate 360 degrees without generating this error? if I set up the maximum value to 361 degrees and then if I rotate 360 the error will not occur and the motor will rotate 360 degrees as I aspected, but it's this correct ? or there is another way to do it? Thanks  
  4. Kinetix 300 servo drive

    Is there a real-time help resource for this thing other than the worthless AB site, on which the support page has been giving an error message for 2 weeks?
  5. Hello everyone! I have problem with understanding the usage/principle of operation of parameter "Mark detection number".  In manual i read: "The number of mark detections is stored. "0" clear is executed at power supply ON. Continuous detection mode: 0 to 65535 (Ring counter) Specified number of detection mode: 0 to 32 Ring buffer mode: 0 to (number of buffers - 1) Refresh cycle: At mark detection" My question is which mark detections are stored? Servo detects some kind of marks? I am novice in servo programming, please explain in the easiest way. Thanks for help.
  6. Servo Motor Connection

    Hello, I am using the R88M-1M40030T-BS2 ( 200V 3ph) servo motor. I am looking for a diagram that explains the connections on the top of motor ( for power supply).. there are more than 3 pins and i am not sure why. Can anyone help me understand the pins on the motor for the 3ph supply?  Thank you

  9. Hi, I am trying to do a merge move on 1S Servo. The condition are as follows: Task: Move 2 in(absolute value) and then Move back to 1 in (absolute value). I have to do this move 10 times in a row.  The application is material leveling after dumping in the mold. The only question i have is if I use just MC_MoveAbsolute command, the only buffer mode for transition available is velocity. Is there a way i can do it with position. I dont want to stop when I can go from 1 to 2 and 2 to 1 again and again. Its time consuming. But rather a nice oscillation motion without stopping to mimic leveling. Can anybody please help me out with this problem.   Thanks
  10. Hi, I'm trying to set up PLC (CJ1G) to control servo motor. I'm using position control unit CJ1W-NC413, servo relay unit XW2B-40J6-2B and smartstep R7D-AP02H servo drive. I'm reading through manuals and feels little overwhelmed with information. Everything is probably there, but it's going to take lot of effort to put it together. Can I found example program somewhere? EDIT: When I put jumper to pin 25 (X axis RUN), motor shaft is locked and motor is holding position, so wiring should be correct. When I try to run a program, I can see that parameters are changing in CX-position, but servo is not moving. Please see attached picture
  11. load cell SP4M-7Kg

    Hello guys, I have a system of 3 load cells (SP4M-7Kg) attached  to a Micrologix 1500 analog inputs. in the same PLC i have 3 coils for a vibrator, each vibrator is working with signal generators. and the load cells with an external 24vdc Power Supply. i see my load cells readings fluctuating too much even with the vibrator not working. if it is set lets say 70 Grams it is jumping from 68.4 to 74.8 going up an down never never stabilizes in one number, so i suspect am getting noise somewhere put a 100uF capacitor PLC inputs for the load cells but weight just increases more and more. How can realize where is the noise comming? what can i use as a filter? how can i improve this system? should i changed it to digital?   any help welcome! thanks.  questions?    
  12. Homing servo motors

    Hello everybody, I have a question about homing servo motors. I have a project with new servos from Omron and I would like to know what is the best way to do homing for the servos and how often. Before when we have servos with encoders I was making special homing sequence and was calling by some event. I heard that new servos from Omron pretty smart and remember own position without batteries. So with this 'new generation' of servos what is the key to keep machine robust, easy for motor replacement without useless programming stuff. Regards, Scotty
  13. Is there a way to change the parameter of a mitsubishi mr-j3a using fx3u plc?  Need this to change the pulse output of a master servo amp to change the pitch of the other slave servo amplifier. 
  14. I am trying to connect a Delta ASDA-A2 Servo internal motor encoder to a Delta DVP28SV high speed counter input.  I was successful in connecting the servo to the plc on position mode with an external encoder connected to PLC high speed counter.  Currently having trouble in finding the correct wiring between the servo drive and the plc to count the pulses from the internal motor encoder.  Attached are some figures from the servo drive manual. OA --> X0 is obvious, tried s/s to GND, COM-, VCC and VDD... no result. Any suggestion would be highly appreciated.  
  15. RS logix 5000 motion control

    Hi Guys! I have a problem with Motion axis move (MAM) command. There is an Allen bradley servo motor what is working well. But I need to add a new program section, wich is in  a specified moment, the axis should move a certain distance. I think I need to use the mam command, just I dont know how can I configure the motion control part. I need to make a new tag ? or what ? I need to use a user define ? PLS help me.   
  16. Gx Works 2 ve fx2n için bir fonksiyon kütüphanesine ihtiyacım var. Servo ve step motor kontrolü için.   thank you
  17. Hello, I have a cp1h-y20dt-d (sinking output) plc supposedly to be wired to a servo controller. The pulse control method is Pulse/Direction. I've did some manual research on the PLC and found the following diagram attached Untitled. Since the diagram above doesnt show which terminals does it connect to in the CP1H side circled red, I want to ask if those connections belong to the following diagram attached Untitled1? If so, assuming im planning to use only Pulse Output1 (Pulse/Direction method) from the PLC side, is the connection from the first diagram no.1=CCW0- , no.2=CCW1- , no.3=COM (connected to -ve) *Note: these diagrams are from omron's manual SYSMAC CP Series CP1H-X40D_-_ CP1H-XA40D_-_ CP1H-Y20DT-D CP1H CPU Unit Your replies would greatly help. Thanks and best regards, Summer

  19. Logix 5000, Array filling

    Hi there! I have a question with AB PLC. My problem:  I have some raw data...distance for example.When the machine starts,the sensor begins to send the information with the distance values. When data is received it is moved into an array. After the first 5 values the program calculates an average and the result is moved into another array.Currently after receiving the fifth value,thus filling the first array,making the calculation and sending the average to the other array,the program empties the entire first array instead of just always discarding the oldest value of the five,and recalculating the average with the newly arrived value every time. I tried to made this with ladder diagram using an an fifo load and unload but isnt working. Please help me if anybody can. Thank You.

  22. RC servo motor sg90

    I new to the Cx-programmer. I'm facing a problem where i need make the servo motor go to certain direction and stop at the direction until other signal is sensed. Is there any instruction which can be used to do the ladder diagram? is it using PWM instruction? Is my servo motor (sg90) suitable for PLC ? do i need motor driver for this servo motor? or i just have to connect to the PLC 5v ? Im using CJ1M CPU21 PLC module. Im doing a sorting system project that use the servo motor to slide the item to certain angle. 
  23. Hello everyone, Is there any way to communicate with Mitsubishi Servo amplifier MR-J2S-350CP through RS232 ,I prefer to use 224XP because i already have it... thank you 
  24. I am currently using a Kinetex 5500 Servo Drive with a VPL Motor and its has vertical load attached to it. My problem is even after setting my Brake Enagaged time to 0.01s it drops like a dime. I had made sure that I kept my Servo STO enable for 5 second before MSO is shutoff and MSF is engaged. Any ideas on what I am doing wrong? Attached is an action parameter settings for brake control.
  25. Hi All,  I was wondering if any of you guys could help me about improving my load sharing application. At the moment it's very unstable and i can't see what i am doing wrong! Thanks.  Details: I am trying to run a industrial chain conveyor using Torque control by Real sensorless vector control function of A700 Mitsubishi VFD. I have been following "Technical Note" which is provided by mitsubishi (see attached PDF).  As described on technical note, i am trying to control 5 motors ( 1 X 2.2kW, 4 X 1.1kW) to share the load on this chain conveyor. Torque command (SV) and Motor Torque (PV) read from Master VFD and PID output (MV) of Q03UDE transferred to Slave VFDs over CC-link. i would appreciate any information and help you can provide, Many Thanks.  Application_Technical_Note_Load_Sharing.pdf
