Galil / Re: Mitsubishi MR-J2-40A with Galil icm 1900 wiring help needed!

« on: November 06, 2011, 12:07:32 PM »

Yes it's very wierd. It has 5 and 15 on the wiring diagram forZ index but the cables arn't wired and they are orignal mits cables. (JC BBL2)

Wondering if the mits encoders can run without the Z index??

I think I will need a very fine soldering iron! I have spare cabling so might try running some along side.

Thanks

Had a go at the wiring today but soon hit a problem. I'm using Mits encoder cables for the CN1A encoder pass through to the galil but found I have no wires coming from pin 5 and pin 15 for the Z index pulse to the icm1900 terminals. I've opened the mits plug but looks a nightmare to resolder..so tiny!

Am I doing something wrong here..any advice on cables..should I be looking at using something else instead of an encoder cable?

Thanks

Sorry Wayne no idea on Dyna Myte control I only have Fanuc! Good luck with the manuals they should be a big help.

Hi i'm not familiar with the parameters on this control but i'm sure it will be in the manual if you have one. Strange that it would need changing though unless you have reloaded the parameters for some reason. Does it alarm out when it sticks on the tool change?

Thanks Nosmo will run in torque mode. I'm a newby with the Mits and the Galil so finding the terminology confusing.

When you say the differential out puts you mean LA and LAR on the Mits to A phase+ and A phase - on the galil for example...just to clarify!

Will leave the 5v as you suggested as the encoder gets this from the drive.

Great help thanks

Hi,

On the Mits manual it says I can run in Position control mode, speed control mode, torque control mode, position/speed control change mode, speed/torque control change mode or torque position control change mode 

If I knew which one to go with that would be a start.

On the Mits CN1A pin outs I have encoder A phase pulse LA pin 6 , B phase pulse LB pin 7, Z phase pulse LZ pin5.

Then LAR is differential line driver pin 16, LBR differential line driver pin 17 and LZR differential line driver pin 15.

On the Galil icm 1900 I have pin 83 X encoder A+, pin 84 X encoder A-, pin 85 X encoder B+,  pin 86X encoder B-, pin 87 X main encoder index +, pin 88 X main encoder index - then pin 89 analogue signal ground and pin 90 +5 volts.

So would I wire pin 6 on the mits to pin 83 on the galil and pin 16 to pin 84. Presume the Z phase on the mits is the index terminal on the Galil.

If I can sort this that will get me going!

Thanks for any help in advance 

John.

That is the best screen set I have seen yet! Is the dual screen set available for download?

Hi Wayne can you check if it's stuck in manual mode. Might be a bad start switch or auto/manual switch. Or a feed hold switch stuck on?

Faulty contacts on switches are a good place to start...if it's been sat idle for some months the contacts can corrode with the damp..or the switch contacts simply wear out on older machines. You can usually check them in the diagnostics screen.

Galil / Mitsubishi MR-J2-40A with Galil icm 1900 wiring help needed!

« on: October 28, 2011, 04:54:26 PM »

Hi,

My first go at a Galil set up with Mach. I'm using two Mitsubishi MR-J2-40A  drives and one MR-J2S-70A.

The problem is, although I have the power side done and the encoder cables connected to the motors, I'm struggling to sort the pin outs from the drive to the Galil icm 1900. I have the diagram for the CN1A connector on the drive and the CN1B connector on the drive.

I also have the terminal list for the icm 1900 but not sure quite what goes to what! I've read that it's best to run these drives in torque mode?

Any pointers? Any help would be appreciated!

John
