A.09 × × × × Dividing
frequency
setting error
The value of dividing
frequency (Pn212 ) is
set to an invalid value.
Or the resolution of
connected encoder is
exceeded.
Cycle
power
Change the
setting of
Pn212
(Pn213) to a
settable value,
and then cycle
control power
or reset the
software.
For linear motors, the
deviding ratio
exceeded the setting
in Pn281.
Cycle
power
Change the
setting range
to inside of the
calculation
result of
Un010, and
then cycle
control power
or reset the
software.
A.0A × × × × Encoder type
unmatched
The attached serial
encoder type is not
supported.
An alarm occurs when
the encoder type is
other than the
followings.
UTS*:

encoder
JZD*:
Σ
-II type serial
encoder (Linear)
Cycle
power
Change the
motor to the
Σ
-II support
type.
A.55 × × Setting error
of linear motor
peak speed
When the linear motor
was connected, the
value more than linear
motor peak speed
was set to Pn384.
resettable Set Pn384 to
below the
linear motor
peak speed.
A. b1 × × × × Reference A/

Reference A/D
breakdown
The A/D conversion
result of 0V and ±5V
generated inside the
servo amplifier shifted
by 1V or more, and
this state continued
for 20ms.
Check only 0V when
the servo is ON, and
check 0V, and ±5V
when the servo is
OFF.
