SDH Series Manual
AL.28 Encoder overheat
Cause Inspection Remedy
Encoder operating
temperature is over 95 ℃ .
Check the encoder is not in high temperature
environment or close to the heat.
1.To avoid high temperature environment
and lower the temperature of the
encoder.
2. If the situation is not improving, please
contact agent for proper service.
AL.29 Encoder error 5
Cause Inspection Remedy
The multi-turn of absolute
encoder exceeds the range.
Check if the multi-turn of absolute encoder
exceeds the maximum range: -32768 ~ +32767
Conduct homing procedure. Please refer
to the description of absolute coordinate
initialization in Chapter 14.
AL.2A Absolute encoder error 1
Cause Inspection Remedy
The voltage of the absolute
encoder battery is lower than
the specification.
Check if the voltage of the battery is lower than
2.45V(TYP).
After changing the battery, please
conduct homing procedure. Please refer
to the description of absolute coordinate
initialization in Chapter 14.
Battery circuit disconnects or
wire broken.
1.Check the wiring of the encoder.
2.Check the wiring between the battery pack
and power cable of the servo drive.
After connecting battery to encoder
correctly or repairing wiring, conduct
homing procedure. Please refer to
the description of absolute coordinate
initialization in Chapter 14.
AL.2B absolute encoder error 2
Cause Inspection Remedy
The value of absolute
encoder multi-revolution
counter is abnormal.
Re-power on the servomotor and check if this
error occurs again.
If the situation is not improving, please
contact agent for proper service.
AL.2C absolute encoder error 3b
Cause Inspection Remedy
Change the battery when
the power is OFF which is
controlled by the servo drive.
Do not change or remove the battery power
when the power is OFF which is controlled by
the servo drive.
Conduct homing procedure. Please refer
to the description of absolute coordinate
initialization in Chapter 14.
Start up with absolute
function and not have
finished absolute coordinate
initialization.
1.Install the battery.
2.Check the wiring between the battery pack
and power cable of the servo drive.
3.Check the wiring of the encoder.
Conduct homing procedure. Please refer
to the description of absolute coordinate
initialization in Chapter 14.
AL.2D encoder battery under voltage
Cause Inspection Remedy
The voltage of the encoder is
lower than the specification.
1. Check if the voltage of the battery on the
panel is lower than 3.0V(TPY).
2. Check if the voltage of the battery is lower
than 3.0V(TPY).
Change the battery when power is ON
which is controlled by the servo drive.
After changing the battery, AL. 2D will be
cleared automatically.
AL.2E Control circuit error
Cause Inspection Remedy
When motor is running and
external loading is bigger, the
situation of servo ON (SON)
OFF becomes ON instantly.
Check if servo ON (SON) turns on. Turn on servo ON (SON) correctly.
