Controller
temperatur
e exceeded
set range.
(01-146)
<Details> The temperature around the power element of the controller is
too high.
<Countermeasures> Make improvements so that the temperature around
the controller is kept appropriate.
Controller
supply
voltage is
outside set
range.
(01-147)
<Contents> The control power supply voltage within the controller is outside
the set range.
<Countermeasure> Make sure that the voltage supplied to the control
power (C24V) of the controller is appropriate.
If a single power supply is used for both the control power and the
motor power, or the power supply is "inrush-current control type", a
power voltage drop may be caused due to a voltage drop during
acceleration/deceleration.
<Contents> The alarm may be caused by regenerative power depending on
the method of operation of the actuator.
<Countermeasure> Make sure that the operating conditions are within the
specifications.
Please refer to the manual or the catalogue of the actuator for the
method of operation of the actuator.
Current
limit is
exceeded
(01-148)
<Contents> The output current accumulated value exceeds the specified
value.
<Countermeasure> Make sure there are no obstructions that interfere with
the actuator movement. Also, make sure that the load, speed, acceleration
and deceleration are within the range of the actuator.
The target
position
was not
reached
within the
set time
limit
(01-149)
<Content> Failed to reach the set position within the set time limit.
<Countermeasure> Make sure there are no obstructions that interfere with
the actuator movement. Also, make sure that the load, speed, acceleration
and deceleration are within the range of the actuator.
Communic
ation error.
(01-150)
<Contents> The connection with the higher-level devices (such as the PC
and teaching box) is disconnected.
<Contents> The connection with the higher-level devices (such as the PC
and teaching box) is disconnected.
In case of the communication failure of PC or teaching box, resetting of
alarm by PC or teaching box is possible after connecting again.
Turn OFF
and ON the
power
supply for
the
controller
<Contents> Abnormality in communication with the encoder.
<Countermeasure> Check the connection of the actuator cable.
Unable to
find motor
phase in
set time.
(01-193)
Turn OFF
and ON the
power
supply for
the
controller
<Contents> Unable to find the motor phase within the set time.
(When the servo motor is turned ON (“SVON” turns ON) for the first time
after the power is applied, the actuator needs to move a little to find the
motor phase. However, if this actuator movement is prevented, this alarm
will be activated.)
<Countermeasure> Make sure there are no obstructions that interfere with the
actuator movement and then turn ON the servo motor (“SVON” turns ON).
