Explanation
NSU01 detected an arithmetic error.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
NSU01 detected an error in the setting value of parameter or file.
Check for an error in the setting of the safety range, then turn the
power OFF and ON again. If this alarm occurs frequently, replace
NSU01 unit.
NSU01 detected an error in the encoder data.
Check the encoder cables, then turn the power OFF and ON again.
Reading encoder data failed multiple times in a row.
Turn the power OFF and ON again.
If this alarm occurs again, replace NSU01 unit.
The safety unit (NSU) has detected the manipulator motion exceeding
the safety range of each axis. Check the teaching points and range
setting.
The safety unit (NSU) has detected the manipulator motion exceeding
the safety range. Check the teaching points, range setting, and
motion speed near the end of the range.
Data inconsistency occurred in the duplicated monitoring by the
safety unit (NSU). One CPU detected an error in the timing check of
the other.
This alarm may be accompanied by the alarm 1610 and 1615.
Turn the power OFF and ON again.
Data inconsistency occurred in the duplicated monitoring by the
safety unit (NSU). The hardware setting failure of one of the dual
systems was detected.
This alarm may occur due to the failure of the rotary switch. Turn the
power OFF and ON again.
Subcode 1: rotary switch setting error
2: other errors
Data inconsistency occurred in the duplicated monitoring by the
safety unit (NSU). Turn the power OFF and ON again. This alarm
occurs when an error was detected in one of the CPUs.
Data inconsistency occurred in the feedback monitoring of the safety
signal outputs. Check the safety signal cables, then turn the power
ON again.
<Check point> Connectors and cables of NSU01: CNLO, CNSF 1 to 4
The internally-generated voltage of NSU fell below the low voltage
threshold. The failure of the unit may have occurred. Replace
NSU01 unit.
The internally-generated voltage of NSU exceeded the over voltage
threshold. The failure of the unit may have occurred. Replace
NSU01 unit.
An error was detected by the hardware diagnosis of NSU.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
An error was detected by the hardware diagnosis of NSU.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
An error was detected by the hardware diagnosis of NSU.
Turn the power OFF and ON again.
If this alarm occurs frequently, replace NSU01 unit.
