Chapter 8 Troubleshooting
The possible faults of 200-N is listed below , and the fault code indicate range is from E001 and E003 ~
E041. Once a fault occurs, you may check it according to the table and record detailed phenomena before
seeking service from the supplier.
8.1 Faults and Actions
Fault
code
Fault categories
Possible reasons of fault
Actions
E001
IGBT module’s
shorted
Too short Acc time
Prolong the Acc time
Inside IGBT is damaged
Seek service
Interference causes the malfunction
Check peripheral equipment whether has
strong interference
Grounded is not good
Seeking service
E003
Over-voltage
during stop
Bus voltage detection disconnect
and bus voltage detection circuit
fault
Detect bus voltage connection and
replace the driving plate
E004
Over-current
during
acceleration
Too short Acc time
Prolong the Acc time
Low AC supply voltage
Check the input power supply
Drive power is too small
Select a higher power drive
E005
Over-current
during
deceleration
Too short Dec time
Prolong the Dec time
Low AC supply voltage
Use suitable dynamic braking kit
Drive power is too small
Select a higher power drive
E006
Over-current in
constant speed
operation
Sudden change of load or abnormal
Check the load or reduce the Sudden
change of load
Low AC supply voltage
Check the AC input power supply
Drive power is too small
Select a higher power drive
E007
Over-voltage
during
acceleration
Abnormal input voltage
Check the input power supply
The rotating motor re-starts after
the drive stops instantly.
Avoid re-start after the drive stops
instantly
E008
Over-voltage
during
deceleration
Too short Dec time
Prolong the Dec time
Too big load inertia
Use big dynamic braking group
Abnormal input voltage
Check the AC supply voltage
E009
Over-voltage
in constant
speed operation
Abnormal change of input voltage
Install input reactor
Too big load inertia
Use suitable dynamic braking group
E010
DC Bus
under-voltage
Low AC supply voltage
Check the AC supply voltage
E011 Motor
over-load
Low AC supply voltage
Check the AC supply voltage
Improper motor’s rated current
Modify motor’s rated current
Load increases suddenly
Check the load, adjust the value of
torque boost
