38520000 hex Function Set-
ting Error
The function that
was set does not
support the com-
munications period.
• The electronic gear object ratio
was not 1:1 when the communi-
cations period was set to 500
μs.
• Modes of operation (6060 hex)
was set to pp or hm when the
communications period was set
to 500 μs.
• More than 12 bytes were
mapped for RxPDO in Fully-
closed Control Mode (This
applies only to Cylinder-type
Servomotors.).
• Modes of operation (6060 hex)
was set to pp or hm in Fully-
closed Control Mode when the
communications period was set
to 1 ms and the electronic gear
parameter ratio was not set to
1:1 (This applies only to Cylin-
der-type Servomotors.).
• No bytes (i.e., no objects) were
mapped for RxPDO.
• More than 10 objects were
mapped for RxPDO.
• More than 11 objects were
mapped for TxPDO.
• CSP Switching Reference Posi-
tion (4020 hex) was mapped for
TxPDO when the communica-
tions period was set to 500 μs
or when the electronic gear
object ratio was not set to 1:1.

38530000 hex Magnetic
Pole Position
Estimation
Error 1
Magnetic pole posi-
tion estimation was
not completed suc-
cessfully.
• Settings associated with the
external encoder are incorrect.
• The command time or force
command value for magnetic
pole position estimation is too
low.
• There is a large unbalanced
load or friction.

No. I577)
38540000 hex Magnetic
Pole Position
Estimation
Error 2
Magnetic pole posi-
tion estimation was
not completed suc-
cessfully because
the motor did not
stop within the
Magnetic Pole Posi-
tion Estimation
Time Limit for Stop.
• The value set for the Magnetic
Pole Position Estimation Time
Limit for Stop (3927 hex) is
small compared with the actual
stop time of the motor.
• The motor is moving when no
force is applied.

Pole Position
Estimation
Error 3
Magnetic pole posi-
tion restoration was
not completed suc-
cessfully.
• The Magnetic Pole Detection
Method (3920 hex) object was
set to 3 (Magnetic pole position
restoration method), although
magnetic pole position estima-
tion had never been executed.
• Th
e Magnetic Pole Detection
Method
(3920 hex) was set to 3
(Magnetic pole position restora-
tion method) when a non-abso-
lute type external encoder was
used.
S Same as
above.
