The position deviation exceeded the parameter settings (Pn520 (2520
hex) × Pn51E (251E hex)/100).
The position deviation exceeded the parameter settings (Pn526 (2526
hex) × Pn528 (2528 hex)/100) when the servo was turned ON.
This warning occurs before an overload alarm (A.710 or A.720) occurs. If
the warning is ignored and operation is continued, an alarm may occur.
Abnormal vibration was detected during motor operation. The detection
level is the same as A.520. Set whether to output an alarm or a warning
by setting Pn310 (2310 hex) (Vibration Detection Switch).
