1Error list
Error no. C1770
1-20
C1770 Error message Origin setting incomplete
Cause The origin is not set.
Measures Re-execute after setting the origin.
C1780 Error message Cannot set origin (illegal axis)
Cause The origin was not set simultaneously for the interference axis.
Measures Set the origin simultaneously for the interference axis. For example, the J3 axis and the J4 axis of the RH
type robot. Please refer to the section of origin setting of separate manual: "ROBOT ARM SETUP & MAIN
-
TENANCE" for details.
C1781 Error message Cannot set origin (SRVON)
Cause The origin was set during servo ON.
Measures Turn the servo OFF before setting the origin.
H179n *n
(n indicates the
axis number (1
to 8).)
Error message Illegal parameter (MEJAR)
Cause The parameter (MEAJAR) setting is illegal.
Or the setting value of the parameter related to addition axis control have exceeded the controllable oper
-
ating range.
Measures The useful range of the operating range setting parameter (MEAJAR) is -131072.00 to +131072.00. Correct,
if the set value is over the range.
Or confirm the setting value of the parameter related to addition axis control.
H1800 * Error message Illegal parameter (MEMAR)
Cause The ABS operation range setting parameter MEMAR setting is incorrect. (Minus side value is larger than
"0", or plus side value is smaller than "0")
Measures Set the value of the parameter "MEMAR" within the limits.
H1810 * Error message Illegal parameter (USERORG)
Cause The user origin setting parameter USERORG setting is incorrect.
Measures Correct the parameter USERORG.
L182n
(n indicates the
axis number (1
to 8).)
Error message Pos. data disagree.Check origin
Cause 1) Position data changed during power off.
2) The fuse (4A fuse) installed at the bottom of the 24 V power supply circuit in the controller may have
blown out. For the fuse blowout, the emergency stop made by the customer may be the cause, or there
may be a ground fault or short circuit with the 24 V power supply in the wiring of a door switch, enabling
device, etc.
Measures 1) Check the origin, re-install if shifting. Re-set up the origin only for the axis which deviated by the ABS
method. Refer to separate "Instruction Manual/ROBOT ARM SETUP & MAINTENANCE" for ABS
method.
2) Investigate and correct the ground fault or short circuit portion in the wiring made by the customer.
Then, replace the fuse inside the controller. Refer to Page 60, "Fig.2-3 ： Fuse (F8) exchange place
(CR750/CR751 controller)" for details. (On details of the fuse, contact the manufacturer.)
L1830 Error message JRC. Exseeds the Pos. limit
Cause The JRC instruction exceeding the operation range was executed.
Measures Check the current position and the operating range.
L184n
(n indicates the
axis number (1
to 8).)
Error message JRC Qtt. Setting Too Large
Cause The movement amount setting of the JRC is excessive.
Measures Correct the JRCQTT parameter.
C1850 Error message Instantaneous power failure
Cause There was the momentary power failure.
Measures Check the power supply connection and power supply state.
L1860 Error message Illegal parameter (TLC)
Cause The setting of the TLC parameter that sets the approach direction was incorrect.
Measures Correct the TLC parameter. (=X/Y/Z)
L1864 Error message FTP parameter setting error (**)
Note) "**" is substituted with the "parameter name".
Cause The FTP communication parameter setting lies outside the range.
Measures Check the setting and correct.
