Meaning
ASIC error occurred in the MECHATROLINK communications.
Internal program error 0 occurred.
Internal program error 1 occurred.
Internal program error 2 occurred.
Internal program error 3 occurred.
Internal program error 4 occurred.
The servomotor ran out of control.
The multiturn for the absolute encoder was not properly cleared or
set.
Communications between the multi-winding drive unit and the
encoder are not possible.
An encoder position data calculation error occurred.
An error occurred in the communications timer between the encoder
and the multi-winding drive unit.
Encoder parameters are faulty.
Contents of communications with encoder are incorrect.
Different multiturn limits have been set in the encoder and the
multi-winding drive unit.
Position error exceeded the value of excessive position error alarm
level (Pn520) when the servomotor 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 servo-
motor power is OFF.
When the position errors remain in the error counter, Pn529 limits
the speed if the servomotor 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).
An error occurred in the synchronization between MECHA-
TROLINK communications and the multi-winding drive unit.
The setting of the MECHATROLINK transmission cycle is out of
the allowable range.
A synchronization error occurs during MECHATROLINK commu-
nications.
A synchronization failure occurs in MECHATROLINK communi-
cations.
A communications error occurs continuously during MECHA-
TROLINK communications.
The transmission cycle fluctuates during MECHATROLINK com-
munications.
A multi-winding drive unit or SERVOPACK DRV alarm 0
occurred.
The safety function signal input timing is faulty.
