G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
50 hex
0 hex External
Encoder
Connection
Error
A disconnection was detected because
communications between the external
encoder and the Servo Drive were
interrupted more than the specified
number of times.
Wire the external encoder as shown in the
wiring diagram.
Correct the connector pin connections.
1 hex External
Encoder
Communicati
ons Data
Error
There was a communications error in
data from external encoder. There was a
data error mainly due to noise.
The external encoder connection cable is
connected, but a communications data
error occurred.
•
Provide the required external encoder
power supply voltage 5 VDC ±5% (4.75
to 5.25 V). Be careful especially when
the external encoder connection cable is
long.
•
If the motor cable and the external
encoder connection cable are bundled
together, separate them.
•
Connect the shield to FG. Refer to the
external encoder connection diagram.
51 hex
0 hex External
Encoder
Status Error 0
Bit 0 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
Eliminate the cause of the error and then
clear the external encoder error.
Then, temporarily turn OFF the control
power supply to reset.
1 hex External
Encoder
Status Error 1
Bit 1 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
2 hex External
Encoder
Status Error 2
Bit 2 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
3 hex External
Encoder
Status Error 3
Bit 3 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
4 hex External
Encoder
Status Error 4
Bit 4 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
5 hex External
Encoder
Status Error 5
Bit 5 of the external encoder error code
(ALMC) was set to “1.”
Refer to the external encoder
specifications.
55 hex
0 hex Phase-A
Connection
Error
An error such as broken wiring was
detected in the external encoder phase-A
connection.
Check the external encoder phase-A
connection.
1 hex Phase-B
Connection
Error
An error such as broken wiring was
detected in the external encoder phase-B
connection.
Check the external encoder phase-B
connection.
2 hex Phase-Z
Connection
Error
An error such as broken wiring was
detected in the external encoder phase-Z
connection.
Check the external encoder phase-Z
connection.
60 hex
0 hex Motor Setting
Error
Settings associated with the motor and
external encoder are not initialized.
Check the specifications of the motor and
external encoder and initialize their
settings.
Error No.
