Press the NC-start key to move the tool changer to the
normal position at the magazine. This is only possible
if the reference points are passed over and the lateral

Note
The feed override is effective, if the override regulator
is on position 0%, the axes will not be moved.
# 41 MOVING FREE MAGAZINE
Press the NC-start key to move the too changer to
normal position.
The command "# 41" is necessary if the loading or
unloading station is not closed or the swivel arm is not
in waiting position at the magazine.
If the EMERGENCY-OFF button has been actuated
during a TOOL Call, a TOOL-DEF or while a tool has
been deposited, this can be removed by # 40 or # 41.

can be selected by pressing the up/down arrow.

This colour change is only activated in the file
KundHelp in manual mode.
Short Description of File KundHelp
The help funktions can be activated after the following
errors.
• Power drop
• Gross positioning error
• Faulty data processing
In all these cases the reference points need to be
passed over. Because of that an automatic sequence
cannot be started

Note
To overcome this the control unit also lists a file
called ServHelp.
