FB 166 BELA-SP
Load spindle
Description
FB 166 sets the bit "Function flag" = manual loading
The block searches for an empty location for the new tool of the spindle in the magazine to be
loaded and reserves the empty location found for the tool change. Then the "D 117.1" bit is
set at the "Acknowledge spindle" interface.
The spindle can be loaded by operating the "Acknowledge" key.
If the "Abort" key is pressed, the empty location found is enabled again.
If no empty location is found, a corresponding message is displayed on the screen and the
"D 117.1" bit is not set. The "Acknowledge spindle" function is interlocked via the bit of the
interface.
In the first cycle, the block checks whether the spindle is already occupied and whether the
tool size entered is valid.
If the scan is negative, a corresponding message is output on the screen and the call of the
submenu display disabled.
