ASDA-A2
AL007：Overspeed
Causes
A dramatic change in
speed
Inappropriate parameter
setting
Torque limit
AL008：Abnormal Pulse Command
Causes
The pulse command
frequency is higher than
the rated input
frequency.
AL009：Excessive Deviation of Position Command
Causes
The maximum position
deviation is set too low
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.
10-14
Checking Method
Use the scope to check if the signal
of analog voltage is abnormal.
Check if the setting of parameter
P2-34 is too small (the condition of
over-speed warning).
1. Check if DI.TRQLM (torque
limit) is used.
2. Check if the default torque limit
of P1-02 is enabled.
3. Check if the torque limit setting
in P1-12 ~ P1-14 is enabled.
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.
Check if the motor is damaged.
Chapter 10 Troubleshooting
Corrective Actions
Adjust the signal changing rate or
enable the filter function
Correctly set parameter P2-34 (the
condition of over-speed warning).
1. Disable the torque limit DI.
2. Disable the default setting.
3. P1-12 ~ P1-14 = 100%
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 the E-gear ratio.
Corrective Actions
Correct the wiring.
Install the encoder again.
Reconnect the wiring.
Change the motor.
