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.
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).
Output
current limit
is
exceeded
set value
(01-194)
Turn OFF
and ON
the power
supply for
the
controller
<Contents> The output current of the power circuit is abnormally high.
<Countermeasure> Make sure that there are no short circuits of actuator
cables, connectors, etc.
In addition, make sure that the actuator is compatible with the controller.
