Overflow
ALM
[6C]
（1-108）
<Contents>
Position deviation counter in the driver has overflowed during the
operation by pulse signals.
<Countermeasure>
Make sure there are no obstructions that interfere with the electric
actuator movement. Also, make sure that the load, speed, acceleration
and deceleration are within the range of the electric actuators.
<Contents>
The motor speed exceeds a specific level due to an external force, etc.
<Countermeasure>
Make improvements such that the motor speed will not exceed the
maximum speed of the electric actuator.
Please refer to the manual or the catalogue of the electric actuator for
the maximum speed of the electric actuator.
<Contents>
The motor power-supply voltage detected in the driver is outside the
specified range. The driver checks the lower limit of the motor power
supply voltage only when the servo ON is commanded.
<Countermeasure>
Make sure that the voltage supplied to the motor power (M24V) of the
driver is within specification.
If the power supply is “inrush current control type”, a voltage drop may
cause an alarm during acceleration/ deceleration.
<Contents>
The alarm may be increased by regenerative power depending on the
method of operation of the electric actuator.
<Countermeasure>
Make sure that the operating conditions are within the specifications.
Please refer to the manual or the catalogue of the electric actuator for
the method of operation of the electric actuator.
<Contents>
The temperature around the power element of the driver is too high.
<Countermeasure>
Make improvements so that the temperature around the driver is kept
appropriate.
