OL1
Overload detection 1
The servomotor or servo driver load level obtained from the motor
current reached the overload level set with the overload detection
level (SV022:OLL).
NR A

OL2
Overload detection 2
A current command exceeding 95% of the driver's max. capacity
continued for 1 sec. or more.
NR A
52
OD1
Excessive error 1 (at servo ON)
The difference of the ideal position and actual position exceeded the
parameter SV023:OD1 (or SV053:OD3) at servo ON.
NR A
53
OD2
Excessive error 2 (at servo OFF)
The difference of the ideal position and actual position exceeded
parameter SV026:OD2 at servo OFF.
NR A
54
OD3
