Error message DSI inconsistency
Cause The duplex DSI status is not consistent.
Measures The duplex DSI signal ON/OFF status is not consistent. Check the following for the DSI.
・ DSI wiring
・ Duplex signal ON/OFF status
・ ON/OFF status switching timing (The error occurs when the ON/OFF status remains inconsistent
between the duplex signals for about 0.2 seconds or more.)
・ Parameter DSINO setting
H2240 * Error message Origin data change
Cause The origin data is changed during execution of the position monitoring function.
Measures The error occurs when the origin data is changed by setting the origin during execution of the position
monitoring function. After turning OFF the power, turn ON the power again to reset the error.
C2250 Error message Safety function execution disabled (No origin setting)
Cause The safety function cannot be executed because the origin is not set.
Measures The safety monitoring function is not activated when the origin is not set. Set the origin.
H2260 * Error message Safety function execution disabled (No extended safety unit)
Cause The extended safety unit of the robot safety option is not connected.
Measures To use the safety monitoring function, it is necessary to connect the extended safety unit of the robot
safety option to the controller. Connect the extended safety unit.
If the error occurs even if the extended safety unit is connected, the extended safety unit may be faulty.
Contact your service provider.
H2300 Error message SLS TCP speed F/B error
Cause An excessive speed feedback is detected by the speed monitoring function.
Measures A speed feedback exceeding the predetermined speed is detected by the speed monitoring function. Check
the robot movement or the monitoring speed setting. Or else, check that the reaction time (parameter
SFREACT) setting is not too short.
H2310 Error message SLS TCP speed command error
Cause An excessive speed command is detected by the speed monitoring function.
Measures A speed command exceeding the predetermined speed is detected by the speed monitoring function. Check
the robot movement or the monitoring speed setting. Or else, check that the reaction time (parameter
SFREACT) setting is not too short.
H2320 Error message SF robot control error
Cause The robot motion command and the feedback are inconsistent.
Measures The robot position command and the feedback position are inconsistent. Check the details of the robot
movement, the terminal load setting, or interference with the peripheral equipment.
H2340 * Error message SF motion command error
Cause A robot motion command error is detected.
Measures An error is detected in the conversion process of the robot motion command. After turning OFF the power,
turn ON the power again to reset the error. If the same error recurs, contact the manufacturer.
