AL006: Overload
Causes Checking Method Corrective Actions
Over the rated loading
of the drive and
continuously excessive
using
Set parameter P0-02 to 11 and
see if the average torque [%] is
over 100% all the time.
Increase the motor capacity or
reduce the load.
The setting of the
control system
parameter is
inappropriate.
1. Check if there is any
mechanical vibration.
2. Check if the acceleration /
deceleration constant is set too
fast.
1.
A
djust the gain value of the
control circuit.
2. Slow down the acceleration /
deceleration setting time.
Wrong wiring of the
motor and the encoder.
Check the wiring of U, V, W and
the encoder.
Correct wiring
The encoder of the
motor is defective.
Send the drive back to the distributors or contact with Delta.
AL007: Overspeed
Causes Checking Method Corrective Actions
Unreasonable
command
Use the scope to check if the
signal of analog voltage is
abnormal.
Less steep command used or
filter applying to smooth
command.
Inappropriate
parameter setting
Check if the setting of parameter
P2-34 is too small (the condition
of over-speed warning).
Correctly set parameter P2-34
(the condition of over-speed
warning).
AL008: Abnormal Pulse Command
Causes Checking Method Corrective Actions
The pulse command
frequency is higher
than the rated input
frequency.
Use the scope to check if the
input frequency is over the rated
input frequency.
Correctly set the input pulse
frequency.
AL009: Excessive Deviation of Position Command
Causes Checking Method Corrective Actions
Parameter P2-35 is set
too small
Check the setting value of
parameter P2-35 (The warning
condition of excessive position
deviation)
Increase the setting value of
P2-35 (The warning condition of
excessive position deviation)
The setting of the gain
value is too small.
Check if the setting value is
appropriate
Correctly adjust the gain value
The torque limit is too Check the torque limit value
Correctly adjust the torque limit
value
