Meaning
Contents of communications with encoder are
incorrect.
Different multiturn limits have been set in the
encoder and the SERVOPACK.
Position error exceeded the value of excessive
position error alarm level (Pn520) when the ser-
vomotor power is 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.
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).
Synchronization error during MECHA-
TROLINK communications with the SERVO-
PACK.
The setting of the MECHATROLINK transmis-
sion cycle is out of the allowable range.
A synchronization error occurs during MECHA-
TROLINK communications.
A synchronization failure occurs in MECHA-
TROLINK communications.
A communications error occurs continuously
during MECHATROLINK communications.
The transmission cycle fluctuates during
MECHATROLINK communications.
A SERVOPACK DRV alarm 0 occurs.
A timeout error occurred when using a
MECHATROLINK command.
