PSM alarm name Cause of alarm Measures of alarm
10 PSM heat sink overheat
alarm The radiator temperature of the power supply
module exceeded the specified value. Reduce the temperature of the power supply
module.
1) The ambient temperature of the power
supply module exceeds the specified
value. 1) Improve the power supply module ambient
temperature and cooling conditions.
2) Use in overload. 2) Check the operation pattern of all motors
connected to the driver module that
supplies power from the power supply
module.
Set a longer acceleration/deceleration time.
Distribute the acceleration of each motor
over time.
Reduce the load.
Increased power supply module capacity.
3) Power supply module failure:
Failure of temperature detection circuit. 3) Replace the power supply module.
11 PSM heat sink thermal
alarm The heat sink thermal that detects the radiator
temperature of the power supply module failed. Turn off the power and then turn it on again.
If the alarm still occurs, there is a possibility of
failure of temperature detection circuit.
Discontinue use and replace the power supply
module.
12 PSM overheat alarm The ambient temperature of the power supply
module exceeded the specified value. Reduce the temperature of the power supply
module.
1) The ambient temperature of the power
supply module exceeds the specified
value. 1) Improve the power supply module ambient
temperature and cooling conditions.
2) Use in overload. 2) Check the operation pattern of all motors
connected to the driver module that
supplies power from the power supply
module.
Set a longer acceleration/deceleration time.
Distribute the acceleration of each motor
over time.
Reduce the load.
3) Power supply module failure:
Failure of temperature detection circuit.
3) Replace the power supply module.
13 PSM thermal alarm The ambient thermal that detects the radiator
temperature of the power supply module failed. Turn off the power and then turn it on again.
If the alarm still occurs, there is a possibility of
failure of temperature detection circuit.
Discontinue use and replace the power supply
module.
14 PSM contactor feedback
alarm The logic of the contactor control output (MC1,
MC2) of the power supply module and the
contactor feedback input (DIN1, COM1) do not
match. Match the logic of the contactor control output
and the contactor feedback input.
1) External magnetic contactor failure. 1) Try replacing the external magnetic
contactor.
2) There is a problem with the wiring
between the external magnetic contactor
and the power module input / output
connector. 2) Check the wiring between the external
contactor and the power supply module.
3) Incorrect logic setting of control output
(MC1, MC2) and feedback input (DIN1,
COM1). 3) Change bit1 "DIN1 logic setting" of PSM
Pr.04 "Contactor feedback monitoring
setting"
4) Power supply module failure:
Related circuit is broken.
4) Replace the power supply module.
