Error causes and solutions
SS2 deceleration time exceeded
The robot didn't stop within deceleration time from SS2 enabled.
Check operation instructions, terminal load, and stop speed (SFSPZERO)
parameter of the robot.
SOS (Position error)
Detect the change of position FB on SOS.
During the SOS monitoring, change in the position FB due to external force was
detected. Remove the external force factor or assess risks and adjust parameter
SOSTLRNC to extend the allowable range of the SOS monitoring.
SOS (Speed error)
Detect FB speed over on SOS.
Please check external force or related parameter settings.
SOS (Position command error)
Detect the change of position CMD on SOS.
Please confirm the robot movement or related parameter setting.
SOS (Speed command error)
Detect CMD speed over on SOS.
Please confirm the robot movement or related parameter setting.
SLS (Joint Speed Error)
Speed monitor detected the speed over.
The speed monitoring function detected a speed exceeding the predetermined
speed.
Check the robot movement or the monitoring speed setting.
Also, check that the deceleration delay (parameter SLSDLY) is not too short.
SLS (XYZ Speed Error)
Speed monitor detected the speed over.
The speed monitoring function detected a speed exceeding the predetermined
speed.
Check the robot movement or the monitoring speed setting.
Also, check that the deceleration delay (parameter SLSDLY) is not too short.
SF robot control error
The robot motion command and the feedback are inconsistent.
The robot's position command and feedback position do not match. Check the
movement of the robot, the load on the hand, and whether the robot is interfering
with any peripheral devices.
SF (Process error)
The Safety Function is not normally executed.
Reset the error by power-cycling the robot. If the same error recurs, contact the
manufacturer.
SF (Process Counter error)
The Safety Function of servo CPU is not normally executed.
Reset the error by power-cycling the robot. If the same error recurs, contact the
manufacturer.
Invalid SCNI number in M_SCNI
Invalid SCNI number is input in M_SCNI.
Enter any value of 1 to 8.
Invalid LOGIC no. in M_SCNILogic
Invalid LOGIC number is input in M_SCNILogic.
Enter any value of 1 to 3.
Invalid SCNO number in M_SCNO
Invalid SCNO number is input in M_SCNO.
Enter any value of 1 to 4.
Safety comm. Received error info
Error information was received from the master station with which the safety
communication function (CC-Link IE TSN) is communicating.
Check the master station error.
