(3) Absolute System Errors (1200 to 1299)
The errors shown in this section are those detected in an absolute system.
Error codes, error causes, error processing, and corrective actions are shown
in Table 2.10.

1201
•
When the servo amplifier power was
switched ON, a sum check error occurred
with the backup data in the controller.
•
Zeroing has not been performed.
•
CPU module battery error.
•
Zeroing was started but it was not
completed normally.
Zeroing
request ON
•
Check the battery of the CPU module and
execute a zeroing.
1202
•
When the servo amplifier power is turned
ON, a communication error in
communication between the servo amplifier
and encoder occurs.
Zeroing
request ON,
servo error
2016 set.
•
Check the motor and encoder cables and
perform zeroing again.
1203
•
During operation, the amount of change in
the encoder current value complies with the
following expression: "Amount of change in
encoder current value/3.5 ms 180
°
of motor
revolution"
After the servo amplifier power has been
turned ON, a continual check is performed
(in both servo ON and OFF states).
1204
•
During operation, the following expression
holds: "Encoder current value (PLS)
≠
feedback current value (PLS) (encoder
effective bit number)".
After the servo amplifier power has been
turned ON , a continual check is performed
(in both servo ON and OFF states).
No
Processing
•
Check the motor and encoder cables.
