APPENDIX 1.4 Servo errors
(1) Servo errors (2000 to 2999)
These errors are detected by the servo amplifier, and the error codes are 
The servo error detection signal (M2408+20n) turns on at the servo 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  to  are for
(Note-1): As for the regenerative alarm (error code ) or overload 1 or 2
(error codes , ), 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 ,  or , it may cause devices
to be destroyed by overheating. Re-start operation after eliminating the
cause of the error certainly.
The hexadecimal display of servo amplifier display servo error code
(#8008+20n) is the same as the LED of servo amplifier.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22)
Programming Manual (REAL MODE) for details of servo errors.
