  1. Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works.     However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003.  This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille

  4. In One of my machine we using one stepper drive thatCTA2H328M-MB model made by Centrust Motors China running without pulse input.Direction and  Enable input only connected. My problem is motor running in low speed since drive is 2.89 Amps and motor is 4.2 Amps so its not supporting.I want change drive capacity but i couldn't found a drive with same concept.I couldn't able to reach the chinese vendor.I have tried many drives which is in my stock all are enable input used for enable/Disable the drive.I am bit confuced. http://www.centrust-motor.com/?c=msg&id=2337 Kindly help what type of drive is this? Which model will suitable for my requirement?  
  5. Greetings every one...!                                         I am using NX1P2 PLC and G5 series Incremental Servo for decoiler machine. Now am facing issue, in the time of feeder working power interrupted then last position values are lost, but I need to retain last position value and feed again remain position. In the case  I am telling about (MC_Axis000.Act.Pos) this variable value I need to store and retrieve it back when power came.                                             Any sysmac software experts give me the best solution for this issue.  Thanks in Advance...!!
  6. Hi,  I want to use the servo drive in internally speed control, how can I change the motor direction? Do you help me for wiring and parameter settings please.  
  7. hallo everyone ...i use mitsubishi Q00UJCPU and QD77MS2.. i try to make a speed control program and the speed wants to be changed during servo operating, i use dedicated instructions ZP. PSTRT1 (axis 1) and have tryed but it was only successful to change speed with "change speed control" function once ... is it like it? cannot change "change speed control" many times when servo operations?
  8. Hello everyone, I'm currently trying to communicate  via ethernet with a Parker drive IPA15-HC. I'm using a 5069-L306ER CompactLogix 5380, revision 30.011. There are add-on instructions that allow you to control the drive, but since they're really basic I'm trying to use message instructions to get more data out of it.  The knowledge base provides a zip named IPA_AOI_Rev4, that includes the add-on instructions and the program you should download to the drive to use them, this is the current file downloaded in the drive. Now, I've tried different msg configurations: CIP Data table read, CIP Data table write, CIP Generic copying the values in the examples and I always get the same:  Error Code: 16#0001 Extended Error Code: 16#0000_0125 That extended error code is nowhere to be found, not in the Logix designer online help and not in rockwell's knowledge base. Any idea?
  9. 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.
  10. 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).
  11.  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  
  12. 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?
  13. 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.
  14. 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

  17. 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
  18. I'm sorry, guys, but I wouldn't be asking if I hadn't dedicated about 12 hours to this already. Long story short: ACS800 with RPBA-01 Profibus Adapter and RTAC-01 Pulse Encoder Interface. All we send to the drive (aside from CW permissives) is a position reference, and I believe the DriveAP functions execute how the drive will achieve that position. My final aim is to separate the encoder from going back to the drive, to instead going to a FM350-1 Counter module. I'm following someone elses work that is long gone, has been changed multiple times, and comments are almost non-existent. Where I'm stuck is understanding the data coming from the drive and being sent to it. PPO Type 5; DPV 0. In Step7, I have a DB for 20 bytes of data to drive and another DB for 20 bytes received from drive. I understand (with respect to data from drive) that it should be: SW; ACT; PZD3...PZD10 (10 x 2 byte Words). But, when I looked through all the settings in the group 51 parameters, the values in the form of (xxyy; index then subgroup; ex: 106 is parameter 1.06) don't seem to exist in the ACS800 Firmware manual. PZD 3 OUT: 7 --- PZD3 IN: 6 PZD 4 OUT: 8 --- PZD4 IN: 10 PZD 5 OUT: 0 --- PZD5 IN: 106 PZD 6 OUT: 0 --- PZD6 IN: 0 PZD 7 OUT: 0 --- PZD7 IN: 611 PZD 8 OUT: 0 --- PZD8 IN: 612 PZD 9 OUT: 0 --- PZD9 IN: 701 PZD 10 OUT: 0 --- PZD 10 IN: 706 The manual says parameter values 1-99 refer to a "Data Set" and each number specifies a certain word in a Data Set. For example, PZD3 IN: 6 refers to Data Set 2 Word 3, which is defined by paramater 92.03. But, that turns up something about short circuit protection, when what my DB value is displaying a distance (from a linear string pot encoder) that matches what the mill is actually at. The ACS800 manual says Data Set Actual Signal words are defined in Group 92. So I looked there: 92: DS Transmit (From Drive) --- 90: DS Receive (From PLC) 92.01: Status Word (Fixed) --- 90.01: 4501 92.02: 103 --- 90.02: 4309 92.03: 402 --- 90.03: 4505 92.04: 412 --- 90.04: 1 92.05:106 --- 90.05: 3 92.06: 0 Any help would be appreciated. Thank you.
  19. 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
  20. My subcontractor use ABB ACS580 instead of ACS880. They argue that can program to control crane with it. Load capacity and motor power is no problem here, but the purpose of inverter I concern here. Is there any advice?
  21. 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
  22. 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. 
  23. 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.  
  24. 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.
