Retrofitting a 1986 Maho MH400E

MAHO offered a lot of options. My lubrication pump is completely independent of the controller. It is fitted with an IG38 timer relay. This runs for 15secs once pressure has been reached, max 60sec, and cycles every 16 or 32 minutes. See attachments.

Y trouble shooting? I bought a second stand alone 602D EXE on ebay for €38 delivered. That was a warmer (hopefully) solution than freezing my arse of in the garage for hours . So once that is wired up, only the X Channel of the original three axis 19A1 EXE board will still be in use. Z is already on a 602D, and Y soon will be.

I took a look at my old parameter list.
Parameter 760 defines the lubrication option:
0=inactive, 1= way dependent, 2= motion dependent

My lubrication was set to "motion dependent" with the following values:
Control time = 15s
Lubrication time 1 = 16min
Lubrication time 2 = 32min
If it was set to "way dependent" there would be the choice of setting axis travel in mm for each axis.
The "Centralized Lubricator" code is really close to option 2.

@Mark: thanx for the G-Code

Does anyone know what the difference is between the e102 and the e102 desired value inputs are on the 3trm2 driver? The manual says it is selected internally. Not sure which one you guys are connecting to the 7i77. The other thing I have noticed is that with nothing connected the servos stay still but when the 7i77 is connected in open loop all axis drift. I have to set each to about -0.0112v to stay still. Signal wires are short and shielded and referanced to ov terminal. Any input is appreciated.

I figured that the Indramat was tuned by MAHO 40 years ago, and the chances of me screwing it up if I try to "improve" it is pretty high. Since the system works, I haven't touched any settings. On mine all axis also drift if open loop, but only slowly. I never noticed whether theer was a difference with or without the Mesa connecte.

With regards to e102, I just connected the MESA 7i77 analog outputs into the same terminals as the Phillips was connected to. Didn't even realise there was that option.

Yesterday I started to wire up my second 602D EXE, only to find that it's output cable has different wire colors to the one I already have.

Analog drives will always drift to some extent.
This should never happen in a working system since the drives should be disabled unless the PID loop is closed
You can null significant offsets via the PID components offset pin

Its important that LinuxCNC control the drive enables so it can disable the drives in case of a following error.
This is a safety issue so its suggested that drive enable control is implemented before you try any tuning or tests with
working drives

Sorry, I miss typed. It should have said e101 and e102. My Philips was connected to both. The indramat manual explained about testing with a battery connected to e102. So I just used that for the input. I wasn't sure if e101 was for high speed jogging or something. I haven't tested it.
While in closed loop it doesn't drift. I just didn't want the offset to make tuning harder.
