A.Cb0
Encoder Echoback Error
Contents of communications with encoder are
incorrect.
Gr.1
N/A
A.CC0
Multiturn Limit Disagreement
Different multiturn limits have been set in the
encoder and the SERVOPACK.
Gr.1
N/A
A.d00
Position Error Overflow
Position error exceeded the value of excessive
position error alarm level (Pn520) when the ser-
vomotor power is ON.
Gr.1
Available
A.d01
Position Error Overflow Alarm
at Servo ON
This alarm occurs if the servomotor power is
turned ON when the position error is greater
than the set value of Pn526 while the servomo-
tor power is OFF.
Gr.1
Available
A.d02
Position Error Overflow Alarm
by Speed Limit at Servo ON
When the position errors remain in the error
counter, Pn529 limits the speed if the servomo-
tor power is turned ON. If Pn529 limits the
speed in such a state, this alarm occurs when
position references are input and the number of
position errors exceeds the value set for the
excessive position error alarm level (Pn520).
