AL029: The internal of the encoder is in error
Causes Checking Method Corrective Actions
The internal address
of the encoder is in
error.
1. Check if the servo is properly
grounded.
2. Check if the encoder cable
separates from the power supply
or the high-current circuit to avoid
the interference.
3. Check if the shielding cables are
used in the wiring of the encoder.
1. Please connect the UVW
connector (color green) to
the heat sink of the servo
drive.
2. Please check if the
encoder cable separates
from the power supply or
the high-current circuit.
3. Please use shielding
mesh.
4. If issue persists, please
send the drive back to the
distributors or contact
Delta.
AL030: Motor crash error
Causes Checking Method Corrective Actions
Motor Crash Error
1. Check if P1-57 is enabled.
2. Check if P1-57 is set too small
and the time of P1-58 is set too
short.
1. If it is enabled by mistake,
please set P1-57 to zero.
2. According to the actual
torque setting, if the value
is set too small, the alarm
will be triggered by
mistake. However, if the
value is set too big, it will
lose the function of
protection.
AL031: Incorrect wiring of the motor power line U, V, W
Causes Checking Method Corrective Actions
The wiring of U, V, W
of the motor is
incorrect connected
or the connection is
breakdown.
Check if U, V, W of the motor is
incorrect connected or the
connection is breakdown.
Follow the user manual to
correctly wire U, V, and W
and make sure it is
grounded.
AL035: Encoder temperature exceeds the protective range
Causes Checking Method Corrective Actions
Encoder temperature
is over 120°C.
Check if the environment
temperature is excessive or the
motor temperature is over 105°C.
Try to reduce operating
temperature.
