fsabbatini Posts: 19 Rating: (0)	Hello again! so i have an 840di cnc with 2 adi4 modules. Everythings seems to be properly connected but when i want to traverse an axis i get the message WAIT: AXIS ENABLE MISSING. I already checked the signals: db31.dbx2.1= 1 db31.dbx1.5 = 1 db31.dbx1.7 = 1 db31.dbx21.7 = 1 the drives are ready, nc ready, hmi ready, everything ok but i never get back the signal db31.dbx93.7 (pulses enabled), this signal is always LOW!! so the question is: what am i missing???! thanks for your help

SteveA Posts: 297 Rating: (41)	Are there any yellow lights on the Diagnosis, Service Display screen? Do you have the number of encoders set to 2, and if so, do you have a second encoder connected and working? HTH, SteveA

fsabbatini Posts: 19 Rating: (0)	Hello Steve, the diagnosis area is differente from the new models (it does not have any green or yellow lights, it's just plain text). Also remember i'm using 2 adi4 modules. Both have their two green lights turned on so everything is fine, the ecoders seems to be working properly (when i disconnect the cable from de module an alam comes out, anyhow i could not turn the axis by hand because the motors are already installed)... when i try to do an optimization test it says Aborted: Pulses Enabled no present, it means signal db31.db93.7 is LOW if you have any more ideas it would be appreciated! thanks!

fsabbatini Posts: 19 Rating: (0)	hello there, this is no new setup, it was a working machine but someone erased the plc program and there is no backup so i'm reprogramming everything... the adi4 has all the enables juped (pin 1 with inputs 5,6,7,8). I also get the DRIVES READY signal from the NC coming form the adi4 modules.... i dont have any more ideas what to do... thanks

Do change the Feedswitch --> can you see the changings ? ( 0-120%) What you can see in the Service-Display from the Axis. The first 4-Bits are for enabled ( from NC, PLC, Conector . . .) Regards Karl

fsabbatini Posts: 19 Rating: (0)	ok there!!! thanks everyone for answering!! but i found the solution to this problem! so here it is, for everyone using adi4: first you start by doing this obvious steps, 1. you set machine data MD13050 $MN_DRIVE_LOGIC_ADDRESS[X]=272 or whatever address you gave the adi4 ports in STEP7 2. you set machine data MD13060 $MN_DRIVE_TELEGRAM_TYPE[X]=3 so it is frame message type 3 as it is set in step 6 adi4 configuration tab and then but not so obvious step is (here was my problem): 3. you set machine data MD13070 $MN_DRIVE_FUNCTION_MASK[0]=FH by default it comes with 0H, this machine data seems to set 611U compliant mode. At first glance i didn't modify this MD because i did not check the 611U compliant mode checkbox in adi4 configuration in the STEP7 hardware settings... the weird thing is that if you DO NOT set this MD, you get all the other signals (ready, etc, etc, etc) but you never get the PULSES ENABLE signal so the control always says "WAIT: ENABLE SIGNAL MISSING or similar) now, i have another problem!!!! haha [snip] ... regards Franco
