9. REAL & VIRTUAL MODE SWITCHING AND STOP/RESTART

This section discusses the procedure for switching between the REAL and

VIRTUAL modes, and the data items which are checked when such switching

occurs.

(1) Switching between the REAL & VIRTUAL modes

Switching between the REAL & VIRTUAL modes is executed by switching the

M2043 signal (REAL/VIRTUAL switching request flag) ON and OFF.

• For REAL mode .......... A REAL mode switching request occurs when M2043

is switched from ON to OFF.

• For VIRTUAL mode .... A VIRTUAL mode switching request occurs when

M2043 is switched from OFF to ON.

(2) REAL & VIRTUAL mode confirmation

The current control mode status (REAL or VIRTUAL) is confirmed by the

ON/OFF status of the M2044 signal (REAL/VIRTUAL mode status).

• M2044 OFF................. REAL mode status.

• M2044 ON................... VIRTUAL mode status.

9.1 Switching from the REAL to VIRTUAL Mode

When a REAL to VIRTUAL mode switching request (M2043 OFF→ ON) occurs,

the following processing occurs.

• Check to determine if switching to the VIRTUAL mode is possible

.................................................................... See Table 9.1

• Output module check.................................. See Table 9.2

• Synchronous encoder axis check............... See Table 9.3

Switching from the REAL to VIRTUAL mode is possible if the check items shown in

Tables 9.1 to 9.3 are all normal.

(1) Check to determine if switching to the VIRTUAL mode is possible

(a) The items shown in Table 9.1 are checked to determine if switching to the

VIRTUAL mode is possible.

All the check items must be normal in order for switching to occur.

(b) If an error exists at any of the Table 9.1 check items, M2045

(REAL/VIRTUAL mode switching error detection flag) will switch ON, and

the error code will be stored at the D9193 to D9195 (REAL/VIRTUAL mode

switching error information storage register) register.

Refer to section 11.6 for details regarding the error codes which are stored

at D9193 to D9195.
