  1. 1756-L73 Major Fault

    Have a 1756-L73 processor that was giving a Type 1 code 60 power up fault, on boot. Changed the ESCM module and placed an SD card in. Now after booting it comes up just fine and in about 10 minutes I get a major fault type 1 code 61. I can reload the project and it will run just fine until the next power cycle. Has anyone come across this one before?
  2. Kinetix 300 fault

    Thanks for the answer kaiser_will, the maintenance crew tightened the conveyor belt to tight causing the problem, too much load on the drive.
  3. Kinetix 300 fault

    I have a Kinetix 300 drive that keeps giving me a E74 fault. I have checked the following and have found nothing. Last summer we had similar problem but not as bad. I opened the panel door and put a fan blowing on the drive stills trips. This drive runs a short, simple belt conveyor, have not found a bad bearing or anything. Any ideas for some of you would be appreciated.   E74 Drive has exceeded peak current limit. Drive cannot regulate current properly. Motor cables shorted. Verify continuity of motor power cables and connector. Motor winding shorted internally. Disconnect motor power cables form the motor. If the motor is difficult to turn by hand, it must be replaced. The machine duty cycle requires an RMS current exceeding the continuous rating of the controller. Change the command profile to reduce speed or increase time. Operation above continuous power rating and/orproduct environmental rating. Verify ambient temperature is not too high. Operate within the continuous power rating. Reduces acceleration rates.The Kinetix 300 drive has a short circuit overcurrent, or failed component. Remove all power and motor connections and preform a continuity check form the DC bus to the U, V, and W motor outputs. If a continuity exists, check for wire fibers between terminal or send drive in for repair.
  4. SLC500 to Compactlogix Migration

    All of you, thank you for the good advice, you brought up some points that I will need to give good consideration to. This is a continuous line, if one piece of equipment goes down the rest can not run because of interlock and it is in sections along the whole line. All of you I'm sure know how it is when you go to the upper management to procure funds for projects they come back and say cut the dollar amount and we will approve it, then again and again. However they have no problem with complaining about the current problems that you are trying to fix. Keep it simple Oldnerd
  5. I have searched AB knowledge base and can not find the answer to my question, maybe I forgotten how to read. I have a project to change 4- SLC 500's over to Compactlogix to get them off DH+ and onto enet, I will replace the processor in each of the 4 racks with a 1747-AENTR and leave the I/O and wiring intact. I have a total of 35 I/O modules in the 4 racks. I have been having difficulty coming up with just which CompactLogix Processor I need to use, on AB knowledge base I seem to be getting conflicting information. Which Compactlogix processor will handle 35 I/O modules ? Any suggestion are welcome. Thanks 
  6. IDEC to ABB VFD

    I have a project where I need to connect an IDEC Smart Axis I/O 40 PLC to 2 ABB ACS 355 VFD drives. The IDEC PLC has an on board Ethernet port but I can find little information on how to program the commands over Ethernet from the PLC to the drives. I have never worked with IDEC before any advice from you  experts would be most helpful. Thanks in advance. Old Nerd
  7. Need Some Advice

    Thanks for getting back with me. I have been on the phone all day on and off with Automation Direct Tech Support. The best I can get from them is " I don't know, it should work." I can talk Modbus 485 with Rx and Wx command, but not with MRX and MWX command. Tech Support says if I can talk with one I should be able to talk with the other. I'm really stuck on this one. I do not know where to go for help. I keep reading everything I can but nothing relating to my problem so far.  
  8. Need Some Advice

    This is my third Automation Direct PLC project. I need any advice from the guru's that know a whole lot more than I do. I'm using a Dl-06DR-D with a D0-DCM in slot 1. I need to control 2 SureServo drives, 2 GS2 drives and 1 GS3 Dura Pulse drive. Also have HMI. I plan to use port 2 for my 2 SureServo drives and port 2 on the D0-DCM module for the GS2's and G3 drive. Any input or tips would be greatly appreciated. oldnerd 
  9. Weintek EMT3105P HMI

    Hello, I am using a Weintek EMT3105P HMI with a 1769-ERML33 AB Compactlogix PLC. I have had the equipment at the customer site up and running for 4 months now with no problem. Now have a problem with the recipe data base. All the formatting is correct, all the addressing is correct. All the items in the numeric input object properties are correct. However it has been converting the data entries for some cells in the recipe database to scientific notation and ignoring the format. I have a recipe input for the number of holes to drill, which writes from the numeric input object to the recipe for number of holes. It is formatted in the numeric input object properties as 3 digits to the left and 0 digits to the right of the decimal point. When I write to this, lets say the value of 2, the number that written to the recipe is 2.45655e40. I have done everything I know to fix this problem, delete, recreate, uninstall the software, the data base and all to no avail. I still have the same issue. If anyone out there has any ideas or experience with this I would appreciate hearing from you. Thanks in advance. Oldnerd
  10. HMI Bit Lamp Object

    Sparky, Thanks, I will do the project different from now on. The advise was sound and when I put in the logic instead of directly inputting to the hmi I had no more problems. It looked to me as though the way it goes is it turns on not off because in worked one way and not the other. I do not like using a off brand HMI with an AB processor, but my boss is super cheap. Thanks for your help.
  11. HMI Bit Lamp Object

    Thank you for the help. I had the input to the PLC mapped directly to the HMI. I changed it to a rung of logic where the PLC input bit turned on and output and the HMI read it and problem solved. Still do not understand why it worked for 4 months and all of a sudden started doing this.
  12. HMI Bit Lamp Object

    I'm new so bare with me. I have ran into something I can not figure out why it does this, need some help from the experts. I have a AB 1769 L33ERM processor with two 1769-IQ16 input modules and two 1769-OB16 output modules. My boss is cheap so he would not buy a PanelView HMI, so I wound up with a Weintek 3105P HMI screen. This was bought from Rohtek and there is no tech support to speak of. Our customer has been running this machine for about four months with no problem. A few days ago the bit lamp on the control screen to tell the operator the e-stop has been pressed came on with out the e-stop being pressed. I had there electrician check the PLC input for voltage and it was at 0 volts. The led for the input on the module was off. I VPN into it and look at the tag in the processor and it was at 0. I went into the HMI software and deleted the bit lamp and re-created it, as soon as I boot up it comes on like the bit from the PLC was on but its not. So I go back and set the bit lamp object to invert the signal it goes off but when the bit in the PLC goes high (pressed the e-stop) it does not come on. The circuit is very simple the e-stops go to the AB safety relay, when the relay is not happy I have a 24 v signal to the PLC input, the HMI bit lamp object turns on when it sees this tag come on. I hope I have been descriptive enough for all to understand, if not let me know and I will try to do better. Thanks for the help in advance.
  13. I to had this problem with a 525, found a config setting wrong, just do not remember which one it was.
  14. Need advice chosing Allen-Bradley PLC

    If you are going to be using AB PLC's often, I would invest in RSLogix 5000 and use Compactlogix line of processor. You can accommodate just about any I/O needs cost effectively.
