Cause
Causes of the error and its countermeasures
Abnormal MC status
The duplex magnetic contactor status signal status is not consistent.
The status of the duplex system for the magnetic contactor (MC) is not consistent. After
turning OFF the power, turn ON the power again to reset the error. If the same error recurs,
contact the manufacturer.
Abnormal SR status
The duplex safety relay status signal status is not consistent.
The status of the duplex system for the safety relay (SR) is not consistent. After turning OFF
the power, turn ON the power again to reset the error. If the same error recurs, contact the
manufacturer.
Power supply fault (5V)
The power supply output voltage is out of the specified range.
The output voltage of the 5V power supply is the specified value or higher/lower. After
turning OFF the power, turn ON the power again to reset the error. If the same error recurs,
contact the manufacturer.
Power supply fault (3.3V)
The power supply output voltage is out of the specified range.
The output voltage of the 3.3V power supply is the specified value or higher/lower. After
turning OFF the power, turn ON the power again to reset the error. If the same error recurs,
contact the manufacturer.
Power supply fault (2.5V)
The power supply output voltage is out of the specified range.
The output voltage of the 2.5V power supply is the specified value or higher/lower. After
turning OFF the power, turn ON the power again to reset the error. If the same error recurs,
contact the manufacturer.
Power supply fault (1.3V)
The power supply output voltage is out of the specified range.
The output voltage of the 1.3V power supply is the specified value or higher/lower. After
turning OFF the power, turn ON the power again to reset the error. If the same error recurs,
contact the manufacturer.
Memory fault (main CPU)
A memory fault is detected.
A fault (inconsistent data between writing/reading, broken retention data) is detected for the
memory (DRAM) to which the main CPU has access. After turning OFF the power, turn ON
the power again to reset the error. If the same error recurs, contact the manufacturer.
Parameter error (xxxxx)
The parameter setting is illegal.
The parameter setting is not correct. Check the parameter setting shown in the "(xxxxx)"
part of the error message, and set an appropriate value.
Inconsistent safety function setting
The enable/disable setting of the safety function is not consistent.
Inconsistency is detected in the enable/disable setting check of the safety monitoring
function. After turning OFF the power, turn ON the power again to reset the error. Then,
check the enable/disable setting of the safety monitoring function.
When the applicable robot is not compatible with the safety monitoring function, disable all
the settings of the safety monitoring function.
SLP robot position error (command)
A position in excess of the limit is detected by the position monitoring function.
The monitoring position calculated based on the robot position command exceeds the
operable area limit defined by the plane of the position monitoring function. Check the
relevant parameter setting such as details of the robot movement or the definition of the
plane.
SLP robot position error (FB)
A position in excess of the limit is detected by the position monitoring function.
