Cause
Bit 0 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
Bit 1 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
Bit 2 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
Bit 3 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
Bit 4 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
Bit 5 of the external encoder error code
(ALMC) was set to 1.
Refer to the external encoder specifications.
An error such as broken wiring was detected
in the external encoder phase-A connection.
An error such as broken wiring was detected
in the external encoder phase-B connection.
An error such as broken wiring was detected
in the external encoder phase-Z connection.
Settings associated with the motor and
external encoder are not initialized.
The rated/maximum current of the motor
exceeds the rated/maximum current allowed
for the Servo Drive.
• The rated current of the motor is too low
compared with the rated current of the
Servo Drive.
• The percentage of the Motor Coil Unit
Mass to the rated force is too high.
• The automatically adjusted Current Loop
Proportional Gain/Current Loop Integral
Gain is too high.
• The percentage of the maximum current to
the rated current of the motor is greater
than 500%.
12 Troubleshooting and Maintenance
Measures
Eliminate the cause of the error and then
clear the external encoder error.
Then, temporarily turn OFF the control
power supply to reset.
Check the external encoder phase A
connection.
Check the external encoder phase-B
connection.
Check the external encoder phase-Z
connection.
Check the specifications of the motor and
external encoder and initialize their settings.
Check the values set for the Motor Rated
Rms Current (3906 hex) and Motor Peak
Absolute Current (3907 hex) objects.
If there is no problem in the set values, the
Servo Drive must be replaced with a higher
capacity Servo Drive.
• Check the value set for the Motor Rated
Rms Current (3906 hex) object. If there is
no problem in the set value, the Servo
Drive must be replaced with a lower
capacity Servo Drive.
• Check the values set for the Motor Rated
Force (3905 hex) and Motor Coil Unit
Mass (3904 hex) objects.
• Check the values set for the Motor Rated
Rms Current (3906 hex), Motor
Inductance (3908 hex), and Motor
Resistance (3909 hex) objects.
• Check the values set for the Motor Peak
Absolute Current (3907 hex) and Motor
Rated Rms Current (3906 hex) objects.
