(2) Turn off the servo power.
(3) Check that the FDD unit (option) is not in operation.
While the FDD is in operation, the LED on the FDD will be lit up. When the power is turned off
while the LED is still lit, the contents of the floppy disk in the FDD may be damaged. While the
FDD is in operation, do not turn off the main power. In addition, to protect the contents of the
floppy disk, it is necessary to remove the disk from the FDD, before turning off the main power.
Note)
If the main power is turned off and then turned on while the system disk is inserted in the FDD,
the controller will be cold started. To prevent this, be sure to turn off the main power after
removing the disk from the FDD.
(4) Check that no editing is being conducted with the controller.
If the main power is turned off while a robot language program is being edited, while position
data is being taught, or while parameters are being edited, data being edited or set may be
lost. (Moreover, other data may be also lost). Editing should be completed before turning off
the main power.
