E93
AUE.A
The current at
U-phase is too
small. (The IGBT
at U-phase is open
circuit or an error
occurs on the
current sensor.)

電機未接線：
重新正確接線
在變頻器輸出側（U／V／W）有使用電磁接觸
器為開路狀態： 確認電磁閥為閉合狀態
1. Verify if the servo drive and the motor are
properly connected
2. The magnetic contactor installed on the
output side (U/V/W) of the servo drive is at
open-circuit. Make sure that it has to be at
close-circuit.

E94
AUE.b
The current at
V-phase is too
small. (The IGBT
at V-phase is open
circuit or an error
occurs on the
current sensor.)
1. Verify if the servo drive and the motor are
properly connected
2. The magnetic contactor installed on the
output side (U/V/W) of the servo drive is at
open-circuit. Make sure that it has to be at
close-circuit.
005Eh 2 3210H
E95
AUE.c
The current at
W-phase is too
small. (The IGBT
at W-phase is open
circuit or an error
occurs on the
current sensor.)
1. Verify if the servo drive and the motor are
properly connected
2. The magnetic contactor installed on the
output side (U/V/W) of the servo drive is at
open-circuit. Make sure that it has to be at
close-circuit.
005Fh 2 3210H
E96
AUE.P
Error occurred on
the encoder (cable
connection error)
1. Verify if the encoder is properly connected
to the servo drive and if the parameters are
correctly set.
2. Reboot the hybrid servo drive.
3. If this fault is persistent, sent it back to the
manufacturer for repairing.
0060h 128 7301H
E101
Software error 1
occurred on
CANopen
(CGdE)
(CANopen
guarding error)
1. Increase guarding time (Index 100C).
2. Check the communication wiring and
grounding. 90 degrees wiring layout or
separation from main circuit is
suggested to prevent interference.
3. Make sure the communication wiring
is serial.
4. Use dedicated CANopen cable and
install terminating resistor.
