Mitsubishi Electric MELSEC Q Series User Manual page 497

The power-up procedure is as follows.
• For AC
1.
Turn on the power.
2.
Set the C Controller module to "RUN".
3.
Turn on the start switch.
4.
When the magnetic contactor (MC) turns on, the output equipment is driven by the user program
*1 : Program the system so that the following operation will be performed at start-up of the C Controller module.
1.
When a battery voltage drop is detected, Ym is turned on.
2.
Yn is turned on at start of the user program.
• For AC/DC
1.
Turn on the power.
2.
Set the C Controller module to "RUN".
3.
When DC power is applied, RA2 is turned on.
4.
When RA2 turns on, XM is turned on.
Upon 100% establishment of the DC input signal, processing is started by the user program
5.
Turn on the start switch.
6.
When the magnetic contact (MC) turns on, the output equipment is driven by the user program
*2 : Program the system so that the following operation will be performed at start-up of the C Controller module.
1.
When a battery voltage drop is detected, Ym is turned on.
2.
Yn is turned on at start of the user program.
3.
After XM turns on and the DC input signal is established, system processing is started.
Create a program so that system processing will start when the DC input signal establishment time has elapsed after
turn-on of XM (the status can be confirmed by the QBF_X_In_BitEx function). (The DC input signal establishment time
is the time taken from "on" of RA2 to 100% establishment of the DC input signal. Set this time to 0.5 seconds.)
However, when a voltage relay is used for RA2, the DC input signal establishment time need not be set in the user
program.
● Q24DHCCPU-V/-VG and Q12DCCPU-V(Extended mode)
Use CCPU_GetErrInfo function QBF_Y_Out_BitEx or QBF_X_In_BitEx function. function.
● Q24DHCCPU-LS and Q26DHCCPU-LS
Refer to the manual of the partner (operating system vendor), or consult the partner (operating system vendor).
