real installation state (CPU base unit/extension base units) at the power supply
on or resetting of the Motion CPU.
• ON .......... Error
• OFF .......... Normal
(a) When an error occurs, the ERR. LED at the front of the CPU turns on.
The error contents can be confirmed using the error list monitor of a
peripheral device started by SW6RN-GSV43P.
(b) When M2041 is on, positioning cannot be started. Remove an error factor,
and turn the power supply on again or reset the Multiple CPU system.
Even if the module which is not set as the system setting with the peripheral device
is installed in the slot, it is not set as the object of an adjustment check. And, the
module which is not set as the system setting cannot be used in the Motion CPU.
(Note): The range of axis No.1 to 8 is valid in the Q172CPU(N).
