Appendix 2 Explanation of Alarms
MITSUBISHI CNC
464
Y20 No spec: Safety observation 0009
Details
“#2313 SV113 SSF8/bitF (Servo function selection 8)”, “#13229 SP229 SFNC9/bitF (Spindle function
9)” and “#21125 SSU_num (Number of dual signal modules)” are set for a system with no safety
observation option.
Remedy
Disable “#2313 SV113 SSF8/bitF (Servo function selection 8)” and “#13229 SP229 SFNC9/bitF
(Spindle function 9)”.
Set “#21125 SSU_num (Number of dual signal modules)” to "0". Restart the NC.
Y20 Safety OBS ERR 0012 (Contactor data)
Details
Contactor's operation is not following the NC's commands.
The contactor showing unusual move will be indicated as a bit.
bit0 : MC_dp1
bit1 : MC_dp2
(Example 1) Operation error only in MC_dp1 : 0001
(Example 2) Operation error in both MC_dp1 and MC_dp2 : 0003
Remedy
- Check if the contactor's auxiliary b contact signal is correctly output to the device set in "#1330
MC_dp1" and "#1331 MC_dp2".
- Check the wiring for contactor shutoff.
- Check for contactor's welding.
- Turn the controller ON again.
Y20 STO function operation illegal 0013
Details
The drive unit's STO function has failed to work properly.
Remedy
If this alarm has occurred alone, a drive unit failure can be suspected.
If other alarms have been generated at the same time, it is also possible that there is communication
problem. Check the optical cable wiring.
Y20 STO function illegal at pwr ON 0014
Details
The motor power has not been shut down with the STO function when the NC power was turned ON.
Remedy
If this alarm has occurred alone, a drive unit failure can be suspected.
If other alarms have been generated at the same time, it is also possible that there is communication
problem. Check the optical cable wiring.
Y20 commanded position error 0015
Details
The stop state of commanded position was released state during the stop monitoring.
Remedy
Check the stop monitoring parameter and user sequence.
Turn the power of controller ON again.
Y20 FB pos error 0016
Details
The stop state of feedback position was released during the stop monitoring.
Remedy
Check the stop monitoring parameter and user sequence.
Turn the power of controller ON again.
