July 2013
With this change sequence, two pocket numbers or two tool numbers must
be transferred in succession. M4520 indicates that another TOOL CALL strobe
(M4073) will follow. Regardless of M4540 or MP7481.x, the pocket number of
the old tool and tool number zero are transferred first.
Zero means clear the spindle!
Acknowledge with M4093. Then the pocket number –1 and tool number of
the new, called tool are transferred.
Pocket number –1 means: no pocket in the tool magazine!
