Cause : The position data cannot be detected properly in the Absolute
applicable type encoder.
1) When the power is supplied for the first time to Simple
Absolute applicable type (before executing absolute reset)
2) Voltage drop of absolute battery
(If the detail code in the alarm list of the teaching tool is
0001
H
.)
3) Wire breakage or connector contact failure of
motor/encoder relay cable or actuator enclosed cables, or
attempted to insert and remove the cables in the simple
absolute applicable type. (Detail Code 0002
H
)
4) Changed the parameters of controller
5) Position data loss in absolute reset process in the battery-
less absolute type.
(Detail Code 0006
H
)
6) Motor has replaced in battery-less absolute type, and the
pairing ID registered in the controller has changed.
(Detail Code 000B
H
)
Countermeasure : 2) Supply the power for 72 hours or more and after
charging the battery enough, perform the
absolute reset operation.
If the same failure occurs often even with
enough battery charge, it is considered the end
of the battery life. Replace the battery.
1), 3), 4), 5), and 6) perform an absolute reset.
Refer to [4.5 Absolute Reset]
Cause : The encoder cannot detect position information normally with
simple absolute specification. (Encoder overspeed error) The
present position changed at a speed higher than the rotation
speed setting due to an external factor at power cutoff.
Countermeasure : Set the rotation velocity to a higher speed than
what currently is. If the same failure occurs again, it
is necessary to have an absolute reset.
Refer to [4.5 Absolute Reset]
Cause : The link to the field network was disconnected on the field
network type controller.
Countermeasure : 1) Revise parameter settings related to the field
network.
2) Check the settings in the host device (master
unit).
3) Check the connection for the network cable.
4) There may be a concern of noise impact. Check
if there is a noise source around the equipment,
and have a counteraction.
Non-volatile memory write
Cause : When data is written to the non-volatile memory, comparison
(verification) is performed to confirm whether the data in the
memory matches the write data. At this time, a mismatch was
detected. (Failure of non-volatile memory)
Countermeasure : If the same phenomenon occurs even after the
power is rebooted, it is necessary to replace the

0A1 Parameter data error
Cause :
The data input range in the parameter area is not appropriate.
Example 1) This error occurs when the magnitude
relationship is apparently inappropriate such as
when 300mm was incorrectly input as the value of
the soft limit negative side while the value of the
soft limit positive side was 200.3mm.
Example 2) It could occur when the soft limit negative side
gets to 0 in case the Index Mode is changed to
Normal Mode in the rotary axis. Set the soft limit
negative side to a value -0.3mm is added to the
outer side of the effective stroke. Refer to [6.1.2
[2] Soft Limit + Side, Soft Limit - Side (Parameter
No. 3, No. 4)]
Example 3) It could occur when the initial positioning band
width
is smaller than the minimum positioning
band width in case an actuator of RCP2, RCP3,
RCP4 or RCP5 Series is connected. Set the initial
positioning band width at or higher than the
minimum positioning band width (lead length ÷
number of encoder pulses: 800) ×3.
Refer to [6.1.2 [8] Positioning Band (In-Position)
Initial Value]
Example 4) Parameter No. 18 Home Sensor Input Polarity is
set to either "1: Albeit Contact" or "2: Break
Contact" in PCON-C B P.
Refer to [6.1.2 [14] Home Sensor Polarity
(Parameter No. 18)]
Countermeasure : Change the value to the appropriate one.
motor/encoder types
Cause : The types of the motor and the encoder set to the parameter
is not defined.
Countermeasure : If this alarm occurs in an actuator subject for
controlling or the same phenomenon occurs even
after the power is rebooted, it is necessary to
CBP
only
Cause : There is an error in the data acquired from the loadcell at the
power booting or software reset.
Countermeasure : 1) There is a concern of noise influence. Check if
there is a source of noise nearby and have a
countermeasure for noise.
2) There is a concern of a malfunction of the
loadcell. Repeating of power reboot and still the
phenomenon occurs, and then there is a
concern of the loadcell malfunction. Consider to
