3.2 Servo errors (SV
)
The following markings show the appropriate method for canceling the error.
AR : Cancel by turning the servo drive unit power OFF, then ON again.
PR : Cancel by turning the NC power OFF, then ON again.
NR : Cancel by resetting the NC.
(Note)
The "SV0050 Overload 1" alarm cannot be canceled unless the reset level or less
has been reached. Refer to the MELDAS AC Servo and Spindle Specifications
Manual (BNP-B3759) for details.
−
: The normal status will automatically return when the warning state is canceled.
