  1. Is the belt a motorized belt? Does it stop moving when there is a real jam or continues sliding under the boxes? Maybe you can monitor the belt's speed to help you decide when you have a real jam. Another idea (in case you must create a gap): Every next belt should move faster than its predecessor.  
  2. Motor Offset or Controller Offset?

    You don't set the value of the Motor Offset. If you do the Commutation Test or know the commutation offset and it is different from the Motor Offset determined by the system then use Controller Offset, introduce your offset value and this is what the drive is going to use. Bye
  3. Motor Offset or Controller Offset?

    From "motion-rm003_-en-p.pdf" "The Commutation Offset attribute is a value that specifies the commutation offset of the PM motor mounted feedback device in units of electrical degrees. This attribute specifies the offset from a commutation reference position defined by applying DC current into the A terminal and out of the shorted B and C terminals of the motor and allowing the rotor to move to its magnetic null position relative to the stator. On an absolute encoder or resolver, the offset is the difference from the device’s zero absolute position and the commutation reference position. On an incremental encoder or Hall sensor with UVW signals, the offset is the difference between the position corresponding to a transition of the commutation device’s W (S3) channel (with the U (S1) channel high and the V (S2) channel low) and the commutation reference position. The commutation offset is only applicable to the motor mounted Feedback 1 device. When the optional Commutation Alignment attribute is supported and set to Controller Offset or Database Offset, the drive shall apply the Commutation Offset value from the controller to determine the electrical angle of the motor. In this case, a valid Commutation Offset value must be entered by the user, read from the Motor Database, or determined by the Commutation Test. In the unusual case where the commutation offset is also stored in the motor, and differs significantly from Commutation Offset value from the controller, the drive shall transition to the Start Inhibited state. If the Commutation Alignment attribute is NOT set to Controller Offet or Database Offset, the Commutation Offset value from the controller is ignored by the drive and the drive must determine its internal commutation offset value by other means. Without a valid commutation offset, the drive shall be Start Inhibited." Bye
  4. 842E-S Absolute Encoder

    Hi, Not sure what your hardware is. Do you have the encoder and the drive in the same ethernet network? What is the encoder mechanically connected to? a motor, a shaft that the drive is moving or following? Please tell me more.  
  5. 842E-S Absolute Encoder

    Hi, In your project tree, right click the encoder and select "properties", select the Configuration Tab, check "Enable Scaling", introduce the resolution you want (for example: 3600) and click "OK" Ah! and read the User Manual (recommended) Hope this helps Bye  
  6. Communication issue between 5069-L320ERM and 2715-B10CD

    Dear pc, This is a whole new topic. According to the knowledgebase subject referenced earlier, Rockwell says there isn't 3.001 AOP so you have to use 2.001 I haven't gone deep on the view designer thing but apparently 3.01 does not create apps for lower versions I must go now but will visit this later Thank you, bye  
  7. Communication issue between 5069-L320ERM and 2715-B10CD

    Issue solved. Finally they get along together I was giving the HMI a wrong path to the controller. My fault.  
  8. Communication issue between 5069-L320ERM and 2715-B10CD

    Thank you for your time pcmc, I really appreciate it. I tried deleting the PV from the tree but they still refuse to work together. I have always added the HMI to the tree in the past with no issues. In this case it is important since the machine is controlled from the HMI and I want the controller to go safe if the communication be lost. (I always prefer to use HMIs for configuration and error reporting, but in this case I have to use it to control the machine as well) This is the first time I utilize this hardware. My client wanted something future-proof and I am hoping I didn't do a bad choice.

  10. Communication issue between 5069-L320ERM and 2715-B10CD

    Yes, the PV is in the I/O Configuration tree under A1, Ethernet. By the way, I am using dual ip Ethernet mode. I am using port A1 for HMI and port A2 for motion control.
  11. Hi cyber-friends, I am working on a project using a CompactLogix 5380 model 5069-L320ERM and a PanelView 5500 model 2715-B10CD. I am developing the PAC app with Logix Designer V 30.00.00 and had to flash the PanelView to V3.001 to be able to download the app from View Designer 3.01 The problem is that the PAC and the HMI refuse to talk to each other and the PAC reports a device mismatch. The PAC allows me to select Panel mayor version 2 only I disabled keying but it didn't work According to knowledgebase subject 1028835 there isn't any V3.001 AOP but there shouldn't be a problem Any suggestion? please
  12. ML1400 encoder wiring

    Hi, You just have to go to the Encoder Products Company website ( download the incremental shaft encoder model 725 datasheet and the Installation and wiring guide. If you do so and you decode your part number you’ll find (please check this) that you have an incremental quadrature open collector encoder with no Z channel. Connect: Terminal F to supply COM Terminal B to +24V Terminal A to PLC A input (I would use I00, the programmer has to tell you which one) Terminal B to PLC B input (I would use I01, the programmer has to tell you which one) Terminal G to ground Leave other terminals unconnected Now, if you look at the wiring guide you’ll find that you have to connect a 2.2K, 1/2W resistor form each input to +24V (my personal preference is to use 1W resistors for high ambient temperature and for long life) Bye
  13. Flex i/o outputs shorting

    Hi Stan, The fuses are placed there to protect the contacts against a shorted solenoid. According to the module installation instructions the recommended fuse size is 3Amp, so my conclusion is that your 2Amp fuses are well sized and you have to focus on what is shorting your outputs. I would check: 1st. If the terminal base is appropriate for the working voltage (see: Installation Instructions) 2nd. If the working voltage is really 120V 3rd. If the solenoid working current is bellow 800mA which the contact capacity for inductive loads I would also consider: 1st. Installing a snubber circuit in parallel to every solenoid (not to the I/O contacts) 2nd. Interposing a higher capacity relay between the I/O contacts and the solenoids  
  14. Sequence Instructions question

    Thank you for taking the time to answer my question Mc. The platform is Logix 5000 In this particular case if any timer times out the outputs are going to change to a safe state and the operator's intervention will be required and the sequence will have to start from the beginning The operator will start the sequence the first time and it has to continue repeating automatically once it reaches the final step I also plan to add a "manual" option so the operator can advance steps one at a time. I still have to read your answer more carefully. At least I know that what I want to do can be done. I'm also going to consider using my own UDTs and AOIs. Thank you again.  
  15. Sequence Instructions question

    Hi, I’m working on a project in which the process has some sequences that I believe I can program using the SQI and SQO instructions. I usually avoid utilizing the built in sequence instructions but this time I think they’re going to save me a lot of programming. My first question is: There are some inputs that I need to ignore in certain steps but I have to look at them in other steps. The problem is the mask is the same for all the steps and I don’t find a way to solve this. Any help? How do I tell the SQI that those inputs can be either 0 or 1 in certain steps but they have to be specific in other steps? Second question: I would like to set a time out limit for every step and want a different limit for every step. Any idea? I have been considering options like writing the ladder the way I usually do or learning SFC but I still think the sequence instructions are the best choice. Thank you.
