( 8 ) Expanded Memory Consistency Check
When the processing program area is provided with
expanded memory, since the memory capacity of
memory board varies, a consistency check is
performed to prohibit the use of expanded memory
in a fault state.
When the processing program area is initialized with
all system numbers, a check is made for the same
memory length as the expanded memory board.
Otherwise, an alarm occurs.

unmatch
(9) Axis Configuration Parameter Consistency Check
After a check is made at power ON for consistency
between the configuration of physical axis and
axis configuration parameters, if axis parameters
determining conditions of system operation are not
s p e c i f i e d c o r r e c t l y , the operation is prohibited.
Detailed explanation follows. A check is made to
see if axis type in physical axis information and
parameter axis information is specified correctly for
feed axis and spindle. A check is made to see if
the number of physical axis is greater than the
number of parameter axis, and if specification of
three axis for one slot is consistent between
physical axis and parameters.
