fault
– Analog input 2 input 2 port exceeds the setting
value of P3.25
Er08-2
Analog input overvoltage
fault
– Analog input 3
The voltage inputted to analog
input 3 port exceeds the setting
value of P3.75
Er09-0
EEPROM fault
–
Read-write fault
The data stored in data storage
area is damaged when reading
data from EEPROM
There is interference to EEPROM
write operation
1.Try again after repower on;
2. If the problem reoccurs for many
times, change the drive.
Er09-1
EEPROM fault
– data
check fault
1. The data read from EEPROM
when power on is different from
that during writing;
2. The drive DSP software
version updates.
1. Reset all parameters;
2. If the problem reoccurs for many
times, change the drive.
Er10-0
Hardware fault
– FPGA
fault
FPGA chip fault
1. Repower on;
2. If the problem reoccurs for many
times, change the drive.
Er10-1
Hardware fault
–
Communication card
fault
External communication card
fault
1. Repower on
2. If the problem reoccurs for many
times, change the communication
card
Er10-2
Hardware fault
– Ground
short circuit fault
During the earth test after power
on, one of motor cables V,W is
short-circuited to the ground
1. Check the connection of the motor
cables;
2. Change the motor cable or test
whether the motor insulation aging
or not.
Er10-3
Hardware fault
– External
input fault
This fault occurs when the digital
terminal configured as external
fault input function acts.
1. Clear the external fault input and
enable fault clearance;
2. Repower on the drive
Er10-4
Hardware
fault
–Emergency stop
fault
This fault occurs when the digital
terminal configured as
emergency stop button acts.
1. Clear the emergency stop input
and enable fault clearance;
2. Repower on the drive
Er10-5
Hardware fault
– 485
communication fault
Strong EMI of 485 communication
circuit causes drive serial
communication alarms
1. Use twisted shielded pairs for 485
communication;
2.Wiring communication cables and
motor power cables separately.
Er11-0
Software fault
– Reentry
of motor control mission
1. CPU loading ratio is too high
2.DSP software fault
1. Reduce the software function;
2. Contact the customers service
and change the DSP software.
Er11-1 Software fault
– Reentry
