If MD 22550 is set to 0, the default setting of MD 22562 should not be altered.
Bit 0=0: Standard response:
The stop occurs on the NC record where the error occurred.
Bit 0=1: If the error occurs in the record with the tool change preparation, the
alarm concerning the preparation command (T) is ignored until the
corresponding tool preparation command (M06) is being interpreted
in the program flow.
At that time, the alarm is issued that was initiated by the preparation
command. It is therefore not possible for the user to make
corrections until this block is reached.
Bit0 = 1: With active tool management only:
In preparing tool changes, the NCK detects only tools with data
assigned to a magazine.
Bit1 = 1: Only with active tool management:
The NCK even loads a tool whose data are known in the NCK, but
which are not assigned to a magazine.
In this case, the NCK attempts to automatically assign the tool data
to the programmed spindle location.
In case of several loadable tools, an active tool is searched again. If
none is available, the tool with the lowest Duplo number is selected.
Bit 2 = 0 active D no. > 0 and active T no. = 0 results in offset zero
active DL no. > 0 and active D no. = 0 results in total offset zero
Bit 2 = 1 active D no. > 0 and active T no. = 0 results in an alarm message
active DL no. > 0 and active D no. = 0 results in an alarm message
Bit 3 and 4: Only significant if tool management is active. Response of init. block
generation on program START if blocked tool is on the spindle and it is to be
activated. See here in particular:
$MC_START_MODE_MASK and $MC_RESET_MODE_MASK.
At RESET in particular, the response 'leave disabled tool' active on the spindle
is not affected.
Bit 3 = 0 If the tool on the spindle is blocked: Generate tool change command
that requests a replacement tool. If there is none an alarm is output.
Bit 3 = 1 The blocked status of the spindle tool is ignored. The tool becomes
active. The following part program should be formulated such that no
parts are machined with the blocked tool.
Bit 4 = 0 An attempt is made to activate the spindle tool and its replacement
tool.
Bit 4 = 1 If the tool on the spindle is blocked T0 is programmed in the start init.
