ASDA-A2
AL008：Abnormal Pulse Command
Causes
The pulse command
frequency is higher than
the rated input
frequency.
AL009：Excessive Deviation of Position Command
Causes
Parameter P2-35 is set
too small
The setting of the gain
value is too small.
The torque limit is too
low.
Excessive external load
Improper setting of E-
gear ratio
AL011：Encoder Error
Causes
Wrong wiring of the
encoder
The encoder is loose
Bad connection of the
encoder
The encoder is damaged Check if the motor is damaged
AL012：Adjustment Error
Causes
The analog input contact
is incorrectly set back to
zero
The detection device is
damaged
AL013：Emergency Stop
Causes
Press the emergency
stop button
10-12
Checking Method
Use the scope to check if the input
frequency is over the rated input
frequency.
Checking Method
Check the setting value of
parameter P2-35 (The warning
condition of excessive position
deviation)
Check if the setting value is
appropriate
Check the torque limit value
Check the external load
Make sure if the proportion of P1-44
and P1-45 is appropriate.
Checking Method
Check if the wiring follows the
suggested wiring of the user
manual.
Check the drive connector of CN2
and encoder
Check if the connection between
CN2 of the drive and the encoder of
the servo motor is loose
Checking Method
Measure if the voltage of the analog
input contact is the same as the
ground voltage
Reset the power supply
Checking Method
Check if the emergency stop button
is enabled.
Chapter 10 Troubleshooting
Corrective Actions
Correctly set the input pulse
frequency.
Corrective Actions
Increase the setting value of P2-35
(The warning condition of
excessive position deviation)
Correctly adjust the gain value
Correctly adjust the torque limit
value
Reduce the external load or
evaluate the motor capacity again
Correctly setup E-gear ratio
Corrective Actions
Correct wiring
Install the encoder again
Reconnect the wiring
Change the motor
Corrective Actions
Correctly ground the analog input
contact
If the error still occurs after reset,
send the drive back to the
distributors or contact with Delta.
Corrective Actions
Activate emergency stop
