Alarm
code
Alarm name Description
Condition at
occurrence
Action
AL40 Overvoltage The main
circuit voltage
exceeded
approx. 400
VDC.
The alarm
occurs during
operation:

Excessive load inertia moment
→ The built-in regenerative resistor does not
function. Connect short bar to R1 and R3
terminals.
→ Connect a regenerative resistor to the R1
and R2 terminals.
→ Increase the deceleration time.
→ Lower the maximum speed.
→ Lower the load inertia moment.

Overvoltage detection circuit error
→ Contact our sales office.
AL41 Regenerative
resistor
overheat
The thermal
switch installed
on the
regenerative
resistor
actuated.
The alarm
occurs during
deceleration:

Insufficient regenerative resistor capacity
→ Install an external regenerative resistor to
raise the regenerative absorption
capacity.
→ When using an external regenerative
resistor in HA-800A-24, set [SP64:
Regenerative resistor selection] to [1:
Use external regenerative resistor].

Regenerative energy processing circuit
error
→ Contact our sales office.
The alarm
occurs after
turning the main
circuit power ON
(HA-800A-24):

The regenerative resistor is not properly
wired or not connected.
→Connect the regenerative resistor correctly.
When an
external
regenerative
resistor is used
(HA-800A-24):

The regenerative resistor is not properly
wired or not connected.
→Connect the regenerative resistor correctly.

The parameter setting of regenerative
resistor selection (SP64) is wrong.
→ Change the setting of system parameter
SP64 and select an external regenerative
resistor.
AL42 Overregenerati
on
(HA-800A-24)
A regenerative
resistor
absorbed
significantly
excessive
regenerative
energy.
The alarm
occurs during
deceleration:

Insufficient regenerative resistor capacity
→ Install an external regenerative resistor to
raise the regenerative absorption
capacity and change the setting of
system parameter SP64.

Regenerative energy processing circuit
error
→ Contact our sales office.
(Replace the HA-800A driver.)

Load inertia exceeds the adaptive range.
→ Review the configuration and use the
resistor with load inertia within the
adaptive range.
→ Suppress the rotation low to reduce
regenerative energy.
The alarm
occurs after
turning the main
circuit power
ON:

The regenerative resistor is not properly
wired or not connected.
→ Connect the regenerative resistor
correctly.
→ Connect a short bar correctly when using
a built-in regenerative resistor.
