*2 All the power supplies for the absolute
encoder have failed and position data was
cleared.
The checksum results of the absolute
*2
encoder memory are abnormal.
Backup battery voltage for the absolute
encoder has dropped.
*2 Data in the encoder is abnormal.
The Servomotor was rotating at 200 r/min or
more when the power was turned ON.
The internal temperature of encoder is too
high.
The A/D converter for speed command
input is defective.
The A/D converter for torque command
input is defective.
Communications LSI error.
A system error occurred in the Servo Driver.
*2
The Servomotor ran out of control.
Phase A or B of the fully-closed encoder
was disconnected.
Phase Z of the fully-closed encoder was dis-
connected.
The multi-turn for the absolute encoder was
*2
not properly cleared or set.
Communications between Servo Driver and
encoder is not possible.
Encoder parameters are incorrect.
*2
Contents of communications with encoder
*2
are incorrect.
Different multi-turn limits have been set in
the encoder and Servo Driver.
Lag pulse of the deviation counter exceeded
the parameter (Pn505).
The Motor-Load Deviation Over Level
(Pn51A) was exceeded for fully-closed
encoder and semi-closed encoder.
