6-86 Error List for the Safety Monitoring Functions
Error causes and solutions
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.
Safety comm. timeout
A timeout error occurred in the safety communication function (CC-Link IE TSN).
・ Check that the parameter "safety refresh monitoring time" set on the master
station is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
Safety comm. timeout
A timeout error (unacceptable delay) has occurred in the safety communication
function (CC-Link IE TSN).
・ Check that the parameter "safety refresh monitoring time" set on the master
station is an appropriate value.
・ Check that the parameter "transmission interval monitoring time" set on the
robot controller is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
Safety comm. timeout
A transmission interval error (communication destination) of the safety
communication function (CC-Link IE TSN) has occurred.
・ Check that the parameter "transmission interval monitoring time" set on the
master station (communication destination) is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
Safety comm. data error
A data error has occurred in the safety communication function (CC-Link IE TSN).
If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
