If the changer arm is stopped for any reason while changing the tools (M06), you must return the
changer arm to the home position manually. However, the countermeasures may differ according to
the cause of trouble. So please find out the exact cause before restoring or repairing the machine.
(1) If the changer arm is stuck while trying to pull out a tool from the spindle (in the state of
Tool Unclamp)
In most cases, this happens when the changer arm is stuck in the spindle while trying to pull out
a tool after tool unclamping is performed , causing to trigger the " 2062 M06 Command Over
Time” alarm.
(2) If the changer arm is stuck in the spindle after changing a tool (in the state of Tool Clamp)

arm changed the tool and performed the tool clamping , causing to trigger the " 2062 M06
Command Overtime” alarm.
