Explanation
The connected board's presence was not confirmed.
This alarm also occurs when an error is detected in the serial
communication between YIF01 and EAXA01 or YIF01 and NSU01.
Subcode 1: YCP01 (main CPU board)
50 to 57: EAXA01
60 to 67: NSU01
An error is detected in the serial communication between YIF01 and
EAXA01 or YIF01 and NSU01.
Subcode 50 to 57: EAXA01
60 to 67: NSU01
An error is detected in the serial communication between YIF01 and
NSU01. The last digit of the alarm number indicates the node
number.
Alarm 0110: NSU 1st node
Alarm 0111: NSU 2nd node
The DX100 has detected an error in the validity check on the data
files between YCP01 and the safety unit (NSU) when the power is
turned ON. Execute "Safety Unit FLASH Erase" in the maintenance
mode.
This alarm also occurs when the functional safety unit is replaced with
the unit whose data has not been set.
An error is detected in the parameter transmission between YIF01
and EAXA board or YIF and NSU.
Subcode: same as the alarm 0021
The DX100 changes its operation modes during a startup process
from the power-on operation until the startup process completion. An
unsuccessful mode change was detected.
Subcode: same as the alarm 0021
The combination of software is incorrect.
Subcode 60: The software version of the functional safety unit
(NSU01) is incorrect.
The DX100 has detected an error in the communication between
YCP01 and the safety unit (NSU) when the power is turned ON.
Check the cables and connectors between these boards, then turn
the power OFF and ON again.
There is a communication error between YIF01 and NSU. There may
be poor contact of connectors. Check the cables and connectors
between these boards, then turn the power OFF and ON again.
The DX100 has detected an error in the communication between the
encoder (each axis) and the safety unit (NSU). Check the encoder
cables, then turn the power OFF and ON again.
The DX100 has detected an error in the communication between the
encoder (all axes) and the safety unit (NSU). Check the encoder
cables and connectors, then turn the power OFF and ON again.
NSU01 could not execute the process successfully.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
NSU01 could not execute the process successfully.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
