  1. Hybrid Stepping Motor 2 Phase on Fx3U-128MT

    It's all in the positioning manual: https://nl3a.mitsubishielectric.com/fa/nl/dl/5493/168593.pdf You can use pulse train outputs of main unit (Y0 to Y2) with built in positioning instructions to control 3 independendent Axis (servo or stepper driver). Up to 200Kp/sec. as i recall. And yes, you need stepper or servo driver. The PLC can provide step/dir signals up to 500mA current.
  2. FX3U Output

    I assume, that it's Fx3U-128MT/ES or /DS If that's the case you have transistor outputs in sink mode and the common terminals(com) should be connected to 0V/GND
  3. FX3U and Servo Amp MR-J4

      J4 amps manifactured after Jan. 2015 with software version B7 have PP2/NP2 inputs for soure interface. Check section 3.6.1 from here: https://pl3a.mitsubishielectric.com/fa/pl/dl/9202/SH(NA)-030107-R.pdf If you are not lucky: Source_Logic_Servo.pdf Both wiring diagrams tested with MR-JE_A. It's the lighter version of MR-J4, but interfaces basiclly the same...
  4. Mitsubishi FX2N Battery Error

    You need to install new or known good battery to clear the battery error. The program is gone. It's great you have copy! I had this issue last year and i end up writing the program my self... it was fun actually! :)  
  5. got 2000

    To 7999!
  6. got 2000

    With factory default settings Fx5U will hold (latch) Data Registers D200 to D7999 when CPU is power off or reset.
  7. Allen Bradley Vs. Mitsubishi

    +1 for Fx5U+GOT Simple. With SSCNETIII/H and CC-Link IEF Basic available, it untie my hands big time in my line of work... If Mitsu add G-code support in IQ-F series, it will become small automation monster.
  8. Try this: Tested with Fx3U and Fx5U CPUs...    
  9. GT work 3 installation error

     Or just rename the extracted insallation folder to shorter one like "GTW3" and run the installation.
  10. FX5 or Q Series Step Motor Control

    How about ClearPath "stepper killer" series... it's NEMA 23/34 compatible deecent closed loop servo at half the price of AC Servo.
  11. FX5 or Q Series Step Motor Control

    Mi advice is to drop the encoder idea! Find someone with experience to tell you if your stepper, drive and power supply are correctly sized for that linear actuator and it's purpose. Make sure to eat with the covers hardware, programming and specially positioning manual for FX5 main unit. You will find all the answers in the literature. Much cheaper Fx3G-14MT can control up to 2 independent Axis...    
  12. Fx5u Servo(jog Program)

    A bit late, but anyway... for JOG i usually use two PLSV instruction for each Axis. forward jog: -------------------[PLSV k1000 k1 m1] reverse jog: -------------------[PLSV k-1000 k1 m1] Negative speed value reverses the motor direction. Be sure to set your acc/dcc timing. With 0 acc/dcc time the motor will start and stop immediately!
  13. How to connect + Program wire encoder

    Pay attention to encoder's operation/installation manual. Look's like this is analogue current or voltage output encoder, so pin 1 (green wire) is 0-5/10V or 4-20/0-20mA. You need to add analogue input adapter (analog to digital) ot your Fx3G. With pin 4 and 5 you should teach zero value position and the rotation direction you want the encoder to output positive analogue value.  
  14. Fx2N-32MT low battery

    I'll be on site next week, but they send me photos of the PLC and the battery was teared from the wires and missing. I assume intentionally. I am facing 100% program loss.

    Thank you Gambit! :)
