49 SOSP Scale overspeed The absolute position liner scale connected to the MAIN side detected
a speed of 45m/s or more when the CNC power was turned ON.
PR A
4A SABS Absolute position detection circuit
error
An error was detected in the scale or scale side circuit of the absolute
position linear scale connected to the MAIN side.
PR A
4B SINC Incremental position detection
circuit error
A speed exceeding the max. movement speed of the absolute position
linear scale connected to the MAIN side was detected.
PR A
50 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
51 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 Excessive error 3 (no power) The motor current is not flowing when the excessive error alarm 1 was
detected.
This occurs when the power line connection is incorrect or broken, or
when there is no bus voltage.
NR A
