Over-speed judgment
parameter is not properly set
Check if over speed judgment
parameter is too small
Set over-speed parameter parameter
correctly
Speed input command
changes drastically
Check if input analog voltage signal is
abnormal
Adjust the change ratio of the input
signal or adjust filter
AL013：Position Deviation is too large
Fault Causes
Check
Solution
The value of position
tracking error is too small
Check if the parameter of P1-37 is
appropriate
Increase the setting value of P1-37
Pulse command frequency is
higher than the norm
Check the frequency of pulse command
Adjust the pulse frequency so that it is
not higher than specification
Gain value is too small
Check if the setting value is appropriate
Set gain value correctly
Torque limit is too low
Check the torque limit value
Adjust torque limit value correctly
Load inertia is too large
Calculate the ratio of load inertia and
rotor inertia
Reduce the load inertia or re-evaluate
the motor capacity
AL014：Input Phase Loss
Fault Causes
Check
Solution
Main circuit power is
abnormal
Check if the L1, L2, L3 power cord is
loose or just has a single phase input
Check if three-phase power is normal
Drive parameter setting is
not correct
Change single-phase power supply to
three-phase power supply
Set the parameters correctly
AL015：Motor phase sequence error
Fault Causes
Check
Solution
Motor UVW phase sequence
error
Check the connection order between the
motor and the drive.
Wiring correctly.
AL016： Drive Parameter Fault
Fault Causes
Check
Solution
Drive parameter input error
Verify if the drive parameters are correct
Input the correct drive parameters
AL017：Braking Resistor Overload
Fault Causes
Check
Solution
Braking resistor is missed or
its capacity too small
1：Check the connection status of the
braking resistor
2：Calculate the braking resistor value
1：Reconnect the braking resistor
2：Use appropriate braking resistor
Braking IGBT is not
effective
Check if the braking IGBT is damaged
Send back to the dealer or the factory
for check
Parameter setting error
check the parameters setting value of
brake resistor (P8-p18) and braking
resistor capacity (P8-20)
Set the parameters correctly
AL018：Encoder Overheat
Fault Causes
Check
Solution
Absolute encoder is overheat
Check if the ambient temperature of
the motor is too high
Reduce the ambient temperature or
conduct air forced cooling for the motor
AL019：The battery of Absolute Encoder is low
Fault Causes
Check
Solution
The battery of absolute encoder is
lower than 3.1V
Measure the voltage value of the
battery
Replace battery
AL01A：Low battery voltage of absolute encoder
Fault Causes
Check
Solution
The battery of absolute encoder is
lower than 2.5V, much position
information is missing
Measure the voltage value of the
battery
Replace battery
AL01B：Drive and motor mismatch
