Probable Cause Conrming Method Corrective Action
4. The encoder is
faulty.
Use a new encoder cable. If the fault
no longer occurs after replacement, it
indicates that the original encoder cable
is damaged.
Place motor at the same position,
power on the system several times and
observe changes of 200B-12h. The
electrical angle must be within ±30°.
Use a new encoder cable.
Replace the servo motor if
the encoder is faulty.
E1.A33: Encoder reads and writes data abnormally
Cause:
Internal parameters of the encoder are abnormal.
Probable Cause Conrming Method Corrective Action
1. The serial
incremental
encoder cable is
broken or loose.
Check wirings.
Check the connection of the
encoder cable to see whether there
is an incorrect connection, a broken
cable, or poor contact. If motor
cables and encoder cables are
bundled together, separate them.
2. Reading and
writing of the
series incremental
encoder
parameters are
abnormal.
If the servo drive is powered off
and on several times but the
fault persists, it indicates that the
encoder is faulty.
Replace the servo motor.
E1.B00: Position deviation excess
Cause:
The position deviation is larger than the setting of 6065h in position control mode.
Probable Cause Conrming Method Corrective Action
1. Power output
(UVW) phase loss
or incorrect phase
sequence occurs in
the servo drive.
Perform motor trial run when there is no
load and check the motor wirings.
Correct the wiring or replace
the cables.
2. The servo drive
UVW cable or the
encoder cable
breaks.
Check wirings.
Reconnect the UVW cables.
The servo motor UVW cables
must be connected to the
corresponding servo drive
UVW cables. If necessary,
replace all cables and ensure
a reliable connection.
