11.5 Protective functions
11.5.1 List of protective functions
A list of PSM protection functions detected by the power supply module is shown below.
(1) Power supply module side
The power supply module alarm (PSM alarm) shown in the table below is detected.
During PSM alarm occurrence, the ERR status lamp (red) on the front panel lights.
For monitoring PSM alarms, refer to the operation manual of the setup support software PANATERM for
Multi.
(2) Driver module side
When a PSM alarm occurs, the DM alarm shown in the table below is generated on all axes of all drive
modules connected to the power supply module.
Multiple PSM alarms are output as a single DM alarm, therefore, check the PSM alarm number if you
want to know the exact cause of the alarm.
To restore both the drive module and the power supply module that have entered the alarm state to
normal, it is necessary to first clear the PSM alarm and then clear the DM alarm for each drive module.
To clear the PSM alarm, it is necessary to remove the cause of the alarm and connect to the power
supply module with the setup support software PANATERM for Multi and press the alarm clear button on
the alarm screen or turn on the control power again.

(Note 1) Alarm attribute : History
✔ indicates that the alarm remains in the PSM alarm history.
✖ indicates that the alarm does not remain in the PSM alarm history.
For the reference of PSM alarm history, refer to the operation manual of the setup support software PANATERM for Multi.
(Note 2) Alarm attribute : Clear
✔ indicates that the PSM alarm can be cleared.
✖ indicates that the PSM alarm can not be cleared.
To clear the alarm of the power supply module, it is necessary to press the alarm clear button on the PSM alarm display of the
setup support software PANATERM for Multi. Please note that the PSM alarm cannot be cleared except by this method.
