Chapter 7 Troubleshooting
Table 7-1 list the possible faults of CV100, the fault code varies from E001 to E050. Once a fault occurs, you may
check it against the table and record the detailed phenomena before seeking service from your supplier.
Table 7-1 Faults and actions
Fault code Fault categories
Possible reasons for fault
Actions
E001
Over-current
during
accerleration
Acc time is too short
Prolong the Acc time
Parameters of motor are wrong
Atuo-tune the parameters of
motor
Coded disc breaks down, when PG is running
Check the coded disc and the
connection
Drive power is too small
Select a higher power drive
V/F curve is not suitable
Check and adjust V/F curve,
adjust torque boost
E002
Over-current
during
deceleration
Deceleration time is too short
Prolong the Dec time
The load generates energy or the load inertial is too big
Connect suitable braking kit
Coded disc breaks down, when PG is running
Check the coded disc and the
connection
Drive power is too small
Select a higher power drive
E003
Over-current in
constant speed
operation
Acceleration /Deceleration time is too short
Prolong Acceleration/
Deceleration time
Sudden change of load or Abnormal load
Check the load
Low AC supply voltage
Check the AC supply voltage
Coded disc breaks down, when PG is running
Check the coded disc and the
connection
Drive power is too small
Select a higher power drive
E004
Over voltage
during
acceleration
Abnormal AC supply voltage
Check the power supply
Too short acceleration time
Prolong accerlation time
E005
Over voltage
during
deceleration
Too short Deceleration time (with reference to
generated energy)
Prolong the deceleration time
The load generates energy or the load inertial
is too big
Connect suitable braking kit
E006
Over voltage in
constant-speed
operating
process
Wrong ASR parameters, when drive run in the vector
control mode
Refer to A5. ASR parameter
seting
Acceleration /Deceleration time is too short
Prolong Acceleration/
Deceleration time
Abnormal AC supply voltage
Check the power supply
Abnormal change of input voltage
Install input reactor
Too big load inertia
Connect suitable braking kit
