AL.04
Regenerative error
Alarm cause
Checking method
Corrective action
Invalid regenerative
brake transistor.
Check if the regenerative brake
transistor is short-circuited.
Send your servo drive
back to the distributor or
manufacturer.
The regenerative
resistor is disconnected
Check the connection of the
regenerative resistor.
Reconnect the
regenerative resistor.
AL.05
Overload 1
Alarm cause
Checking method
Corrective action
The load is over the
rated value
continuously.
Check if the load is too large.
Increase the motor
capacity or reduce the
load.
Improper parameter
setting.
Check if there is any mechanical
vibration.
Execute auto
acceleration/deceleration
tuning.
Unstable system.
Acceleration/deceleration time
constant is too short.
Increase acceleration/
deceleration time.
Incorrect wiring of
motor and encoder.
Check if the wiring of the UVW
and the position encoder cables
are correct.
Wiring correctly.
AL.06
Over speed
Alarm cause
Checking method
Corrective action
The input frequency of
the pulse command is
too high.
Check whether the input
frequency of the pulse command
is too high.
Correctly set the pulse
frequency.
Improper setting for
acceleration/decelerati
on time parameter.
Check whether the acceleration
/deceleration time constant is too
short.
Increase the acceleration
/deceleration time
constant.
Unstable servo system
which cause large
overshoot.
Check whether the system has
been vibrating.
1. Set proper gain value.
2. if it’s not working,
(a)decrease the load
inertia ratio.
(b)change the accelerate
/decelerate time constant.
