Hello freinds,
We are Troubleshooting a Matsuura RA-I pallet changing cnc machine. When a tool change code is given in the mdi / program mode (T** M06) it gives an alarm and user messages and "PS alarm" LED blinks.
Alarm 182: seq error2
User message
411 : T -command is Nothing
425 : read ineffect at mag. stop
x - Axis Interlock on
we confirmed that following need are met.
Z at Home Position
Arm at Home Position
Pot Up
Pot Not Down
Spindle Orient
We have given the air pressure. with diagnose menu we have checked all sensors function in tool pot post. checked the position and confirmed that the tool change arm is in home position. checked all 3 sensors function with diagnose menu.
the tool post can be rotated with handle mode with oparate push button. when the tool change command is given in mdi mode it falls in to above alarm.
what can be the problem . Anyone have suggestions?

425 indicates LS24. When magazine indexes LS24 is not on when the count reaches the tool called.
DGN 1029.5 is LS24.
20 tool or 30 tool mag?

thanks for the reply
its a 20 tool mag.
As you have told we looked into the LS 24. we rotated the magazine by manual push button and monitored the 1029.5 bit and it toggles when rotating, and when the mag stops in a desired position LS24 sensor stays on and 1029.5 bit goes to 0( see picture).
