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! :)  

To 7999!

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

+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.

Try this: Tested with Fx3U and Fx5U CPUs...    

 Or just rename the extracted insallation folder to shorter one like "GTW3" and run the installation.

How about ClearPath "stepper killer" series... it's NEMA 23/34 compatible deecent closed loop servo at half the price of AC Servo.

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...    

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!

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.  

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! :)

So if can get the program from the manufacturer, replace the battery with new one and load the program with GX W2 should work until the battery dies again, right?

Hello all, I was asked to visit a remote location facility with non working machine equipped with Fx2N-32MT PLC. No much info on the problem, but from what i know, the battery is gone and the program wont run. So i guess, that the program in ram is gone. Not much familiar with Fx2N series... No memory cassette installed under the front cover and no program backup of any form. What are my options here?   

When you use relative coordinate system, just put negative sign (-) in front of pulse count. The positioning instruction look's for the pulse sign int to cw/ccw the servo [DDRVI k-1000 k1000 y0 y4]
