APPENDIX 2.4 Servo errors

If a controller, servo amplifier or vector inverter self-diagnosis error occurs, check the points
stated in this manual and clear the error.
(1) Servo amplifier errors (2000 to 2799)
These errors are detected by the servo amplifier, and the error codes are [2000]
to [2799].
The servo error detection signal (M2408+20n) turns on at the servo amplifier
error occurrence. Eliminate the error cause, reset the servo amplifier error by
turning on the servo error reset command (M3208+20n) and perform re-start.
(The servo error detection signal does not turn on because the codes [2100] to
[2499] are for warnings.)
(Note-1): As for the excessive regeneration (error code [2030]) or overload 1 or 2
(error codes [2050], [2051]), the state at the operation is held also for
after the protection circuit operation in the servo amplifier. The memory
contents are cleared with the external power supply off, but are not
cleared by the reset signal.
(Note-2): If resetting by turning off the external power supply is repeated at the
occurrence of error code [2030], [2050] or [2051], it may cause devices
to be destroyed by overheating. Re-start operation after eliminating the
cause of the error certainly.
(2) Vector inverter errors (2300 to 2799)
These errors are detected by the vector inverter, and the error codes are [2300]
to [2799].
The servo error detection signal (M2408+20n) turns on at the vector inverter error
occurrence. Eliminate the error cause, reset the servo amplifier error by turning
on the servo error reset command (M3208+20n) and perform re-start. (The servo
error detection signal does not turn on because the codes [2100] to [2499] are for
warnings.)
Details of servo errors are shown in Table 2.13.
