(3) REAL/VIRTUAL mode switching errors

A check for REAL/VIRTUAL mode switching errors occurs when the

REAL/VIRTUAL mode switching request flag (M2043) switches from OFF to

ON, and from ON to OFF. (See Sections 9.1 and 9.2 for the check content.) If

an error is found, the following occur:

• REAL/VIRTUAL mode switching will not occur, and the current mode will be

maintained.

• The REAL/VIRTUAL mode switching error detection flag (M2045) switches

ON.

• The corresponding error code will be stored in the REAL/VIRTUAL mode

switching error information register (D9193 to D9195).

POINT

(1) The error codes stored in the D9193 to D9195 storage registers which

apply to axis errors are shown below.
