Hi

Found a helpful library file on this forum. MX40-HA.zip

M201= call in pallet#1,continue if pallet#1 is current
M202= call in pallet#2,continue if pallet#2 is current
M203= empty tool from spindle
M204= call WARMUP cycle for machine
M205= empty thru tool coolant line with air blow

If i use M201 or M202 when the right palett is "in" the machine, nothing happens and everything is ok

If I use M201 or M202 when the wrong palett is "in" the machine, i got an Alarm :

2207 ALARM-B Expression: factor 512F

Machine MA-600HB 2008/07
OSP-P200M

M203,M204 and M205 works great

Is there somebody who may know what causes this?
