A09
Gr.1
2nd Channel
Current Detection
Error
The average of the Iv digital quantity
read from the 2st channel for 2048
times is greater than 1500 during Servo
ON.
Contact ESTUN or the
Authorized Distributor.
A0A
Gr.1
Handshake Error
The handshake between DSP and
FPGA failed.
Contact ESTUN or the
Authorized Distributor.
A11
Gr.1
IPM Junction
Temperature
Error
The junction temperature of the
Intelligent Power Module is greater
than the setting value of Pn534.
Reduce the load.
A12
Gr.1
Overcurrent
An overcurrent flowed through the
Intelligent Power Module.
Check if the Motor was
blocked.
A13
Gr.1
Overvoltage
The bus voltage is greater than 420 V.
Try to modify the
Motor running track to
make it run more
smoothly.
A14
Gr.1
Undervoltage
The bus voltage is lower than 165 V.
If the main power
supply system is
normal, contact
ESTUN or the
Authorized Distributor.
A15
Gr.2
Discharge
Resistor
Damaged
The discharge resistor is damaged or
unconnected.
Check whether the
regenerative resistor is
connected
A16
Gr.1
Discharging
Error
The discharging operation is abnormal.
Check the sizing of
regenerative resistor.
A18
Gr.1
IPM Overheated
The temperature of the Intelligent
Power Module is greater than
threshold.
Check the ambient
temperature and
derating the load.
A1A
Gr.2
Charging
Resistor
Overload
The main circuit power supply was
frequently turned ON and OFF.
Delay the interval
between the two power-
up.
A1B
Gr.2
DB Circuit
Damaged
The circuit of the Dynamic Brake is
damaged.
Contact ESTUN or the
Authorized Distributor.
A1C
Gr.2

worked for more than 30 seconds.
Contact ESTUN or the
Authorized Distributor.
A1D
Gr.1
Temperature
Sensor of Drive
Board Error
The NTC temperature sensor is not
connected or broken
Contact ESTUN or the
Authorized Distributor.
A1E
Gr.1
Main Circuit
Charging Error
The charging resistor on the main
circuit was damaged or the P1 terminal
and the P2 terminal are not shorted.
Check if the P1
terminal and P2
terminal is properly
connected.
A1F
Gr.1
Main Circuit
Grounding Error
The main circuit was not grounded.
Check if short cut of
Drive or Motor occurs.
A20
Gr.1
Power Supply
Line Lost
The voltage was low for more than one
second for phase R, S, or T when the
main power supply was ON.
Check if the three-
phase power supply is
connected to the Drive
properly.
