Main circuit OFF
warning
If the main circuit is turned OFF
while the servo OFF command
(M3215+20n) is ON, the main
circuit OFF warning 2149(E9) will
not occur.
If the main circuit is turned OFF
while the servo OFF command
(M3215+20n) is ON, the main
circuit OFF warning 2149(E9) will
occur.
The warning occurs when the main
circuit is turned OFF while the servo
OFF command (M3215+20n) is ON.
In order not to turn ON the main circuit
OFF warning 2149(E9), change the
PC18 servo parameter from
“0
(H)” to “1 (H)”.
