A75
Gr.1
DC Sync Cycle
Time Error
The DC synchronization period or the
setting value of the 60C2 object is not
an integer multiple of 125us, or less
than 125us.

Check if the setting
of DC
synchronization
period is proper.

Check and correct the
setting of 60C2h.
A76
Gr.1
Acceleration
Object Set Error
Acceleration is set to 0 in PP/PV
mode.
Change the Object
6086h, 6084h and
6085h to a proper
value.
A81
Gr.1
U, V, W Wiring
Error
The U, V, W wiring of the Motor is not
correct.
Check if the Motor
power lines (U, V, and
W phases) is connected
properly.
A82
Gr.1
Motor
Mismatched
When Pn895.0 was set to 0 (Use the
data in the encoder zone 1), and
Pn895.1 was set to 1 (Use the
parameter settings), this alarm
occurred if the set value of Pn807 is
different from data (Motor power) in
the encoder zone 1.
Replace the Motor.
A83
Gr.1
Motor Running
Error

The wiring of the Motor was
abnormal.

The Motor was driven in reverse for
power generation.

Check and correct the
order of phases U, V,
and W in the Motor
wiring.

Check and determine
the Motor is not
driven in the reverse
direction.
A90
Gr.1
Phase A
Disconnected
Phase A of the external encoder is
disconnected.

Check the setting of
Pn210.

Check the wiring of
the external encoder.
A91
Gr.1
Phase B
Disconnected
Phase B of the external encoder is
disconnected.
A92
Gr.1
Phase C
Disconnected
Phase C of the external encoder is
disconnected.

Check the settings of
Pn210 and Pn211.

Check the wiring of
the external encoder.
A93
Gr.1
Encoder
Communications
Error
Communications between the external
encoder and the Drive is unavailable.
Contact ESTUN or the
Authorized Distributor.
A94
Gr.1
Position
Deviation
Overflow
The setting of Pn212 (Excessive
Position Deviation Alarm Level) was
exceeded by the position deviation
while the servo was ON.

Check the settings of
Pn210, Pn212, Pn213
and Pn214.

Check the wiring of
the external encoder.

Check if the
mechanical
connection structure
is loose, slippery or
has a large gap.
