Monitoring the DO level status through H0B-05
If the logic of all the three DO terminals are active at low level, the DO1 is high level and DO2 to DO5
terminals are low level, and the corresponding binary number is "001". In this case, the value of H0B-05
(Monitored DO signal) read by the software tool is 1 (decimal). The keypad display is as follows.
DO3 DO1

If the logic of all the three DOs are active at high level, the DO1 terminal is low level and DO2 to DO5
terminals are high level, the corresponding binary number is "110", and the value of H0B-05 (Monitored
DO signal) read by the software tool is 6 (decimal). The keypad display is as follows.

Exit
The forced DO function is not retentive upon power-off. Normal DOs apply after restart, or you can set
H0D-17 (Forced DI/DO selection) to 0 (No operation) to return to the normal DO mode.
3 Forced DO signals controlled by the bus
After this function is enabled, all DO signal levels are controlled by 60FE-01h (Physical output).
In cases where the servo motor is used for vertical motion, if the brake output signal (FunOUT.9: BK,
brake output) is active, the brake will be released and the load may fall. Therefore, take protective
measures on the machine to prevent falling.
