GT200 series general purpose inverter instruction manual
Chapter 5 Fault Countermeasures and Abnormality
Handling
5.1 Fault Phenomena and Countermeasures
When the inverter is abnormal, LED digit tube will display corresponding fault
codes and its contents, the inverter will stop outputting, when a fault occurs, if the motor
is rotating, it will park freely, till it stops rotating.
Fault types of the inverter which may
occur are shown in Table 5-1, when the inverter is fault, users should carry out examination
according to this table first, and record fault phenomena in details, when technical services are
required, please contact the After sale Dept. of our company directly, or contact dealers of the
company.
Table 5-1 Fault Alarming Contents and Countermeasures
Fault
Code
Fault Type
Possible Fault Reasons
Countermeasures
E001
Inverter
accelerating
running
overcurrent
Accelerating time is too short
Lengthen accelerating time
V/F curve is not suitable
Adjust V/F curve settings, adjust
manual torque lifting, or correctly
set motor parameters to guarantee
normal torque lifting
When instant stop occurs, restart
is implemented for rotating
motors.
The start method F2.00 is set to
rotational speed tracking restart
function
Power grid voltage is too low
Check input power supply
Inverter power is too low
Select the inverter of large power
level.
E002
Inverter
decelerating
running
overcurrent
Decelerating time is too short
Lengthen the decelerating time
There’s any potential energy load
or load inertia torque is large.
External proper energy
consumption braking parts.
Inverter power is low
Select the inverter of large power
level.
E003
Inverter
constant-spe
ed running
overcurrent
Load changes in a sudden
Reduce sudden change in load
Accelerating and decelerating
time is set too short
Properly lengthen the accelerating
and decelerating time
Load abnormal
Carry out load check.
Power grid voltage is low
Check input power supply
Inverter power is low
Select the inverter of large power
level
