Er08-1
AI overvoltage fault–AI 2
The voltage input to the port
of analog input 2 exceeds
the setting of P3.25.
proper.
3. Set P3.22, P3.25, and P3.75 to
0 to disable protection.
Er09-0
EEPROM fault–
Read/write error
1. Data is damaged in the
data storage area when the
drive reads data from the
EEPROM.
2. Writing data to the
EEPROM is disturbed.
1. Try again after repower-on.
2. If the fault occurs repeatedly,
replace the drive.
Er09-1
EEPROM fault–Data
check error
1. The data read from
EEPROM during power-on is
different from the data that is
written.
2. The driver DSP version is
updated.
1. Set all parameters again.
2. If the fault occurs repeatedly,
replace the drive.
Er10-0
Hardware fault–FPGA
fault
The FPGA on the control
board reports a fault.
1. Repower on the control board.
2. If the fault occurs repeatedly,
replace the drive.
Er10-1
Hardware fault–
Communication card fault
The external communication
card is faulty.
1. Perform repower-on.
2. If the fault occurs repeatedly,
replace the communication card.
Er10-2
Hardware fault–Ground
short-connection fault
One of the motor cables V
and W is short connected to
the ground, which is found in
ground short-connection
detection during drive
power-on.
1. Ensure motor cables are
connected properly.
2. Replace motor cables
Er10-3
Hardware fault–External
input fault
This fault occurs when the
digital terminal configured
with the external fault input
function acts.
1. Clear the external fault input.
2. Repower on the drive.
Er10-4
Hardware fault–
Emergency stop fault
This fault occurs when the
digital terminal configured
with the emergency stop
function acts.
1. Clear the emergency stop
input.
2. Repower on the drive.
Er10-5
Hardware fault–RS485
communication fault
Strong EMI on RS485
communication circuit
1. Use shielded twisted pairs for
RS485 communication.
