Error details and cause
The operation went outside of the stored stroke limit.
Operation mode is not specified.
• The rotating angle of the block joint during normal
line control exceeded the limit.
• When rotating on the inside of an arc with normal
line control type , the setting value of G-code
control system parameter "normal line control axis
rotating radius" is larger than the arc radius.
With "[St.3216] Resetting" ON, "[Rq.3377] Automatic
operation start (cycle start)" was turned ON.
• External stop signal was ON at G-code control
request.
• External stop signal turned ON during G-code
control.
• External signal FLS (upper stroke limit) was OFF at
G-code control request.
• External signal FLS (upper stroke limit) turned OFF
during G-code control.
• External signal RLS (lower stroke limit) was OFF at
G-code control request.
• External signal RLS (lower stroke limit) turned OFF
during G-code control.
• "[Rq.1120] PLC ready flag" or "PCPU preparation
completion flag" was OFF at G-code control
request.
• "[Rq.1120] PLC ready flag" or "PCPU preparation
completion flag" turned OFF during G-code control.
"[St.1040] Start accept flag" was ON.
"[St.1069] Home position return request" was ON.
• "[St.1068] Servo error detection" was ON at G-code
control request.
• "[St.1068] Servo error detection" turned ON during
G-code control.
• "[St.1075] Servo ready" was OFF at G-code control
request.
(1) Servo amplifier power supply OFF
(2) Initial processing by servo amplifier power
supply ON
(3) Servo amplifier not installed
(4) Servo error occurrence
(5) Cable failure
(6) "[Rq.1155] Servo OFF command" is ON
• During G-code control, the servo amplifier power
supply turned OFF. (not installed detection, cable
failure etc.)
While ending G-code control, "[Rq.1120] PLC ready
flag" turned OFFON again.
Corrective action
• With G-code control OFF, move the machine inside
the limit range.
• Review the G-code control axis parameter "stored
stroke limit".
Set the operation mode.
• Review the setting value of the G-code control
system parameter "minimum rotating angle" or the
rotating angle.
• Review the setting value of G-code system
parameter "normal line control axis rotating radius".
• When starting operation with "[St.3208] During G-
code control" turned ON, OFFON "[Rq.3380]
Reset command".
Turn ON "[Rq.3377] Automatic operation start (cycle
start)" after waiting for "[Rq.3217] Reset complete" to
turn ON.
Turn ON "[Rq.3376] G-code control request" with the
external stop signal turned OFF.
Move in the reverse direction to within the external
limit range, and turn ON "[Rq.3376] G-code control
request".
Move in the forward direction to within the external
limit range, and turn ON "[Rq.3376] G-code control
request".
• Change the Motion CPU mode to RUN.
• Turn ON "[Rq.1120] PLC ready flag".
• After the above, turn ON "[Rq.3376] G-code control
request".
With "[St.1040] Start accept flag" turned OFF, turn ON
"[Rq.3376] G-code control request".
Turn ON "[Rq.3376] G-code control request" after
executing home position return.
Remove the error on the servo side, and turn ON
"[Rq.3376] G-code control request" after resetting
"[St.1068] Servo error detection" by "[Rq.1148] Servo
error reset command".
• Turn ON servo amplifier power supply or check the
cable connected to the servo amplifier.
• Turn ON "[Rq.3376] G-code control request" with
"[St.1075] Servo ready" turned ON.
After "[St.3208] During G-code control" of all lines
turns OFF, turn ON "[Rq.3376] G-control request" with
"[Rq.1120] PLC ready flag" turned ON.
