Fault
Fault reasons
Counter-measures
E0011 CPU
fault
•
CPU abnormal
•
Detect at power on after completely
power outage
•
Seek technical support
E0012
Parameter
auto-tuning fault
•
Parameter auto-tuning is timeout
•
Check the motor connection
•
Input correct nameplates parameters
•
Seek technical support
E0013
Soft start contactor
failed
•
Contactor fault
•
Control circuit fault
•
Replace the contactor
•
Seek technical support
E0014
Current detection
fault
•
Current detection circuit is
damaged
•
Contact the supplier for repairing
E0015
Input voltage phase
loss
•
For three-phase input HD3L, Input
voltage phase loss fault occurs to
power input
•
Check the three-phase power input
•
Seek technical support
E0016
Output voltage
phase loss
•
Output voltage phase
disconnection or loss
•
Three-phase load of HD3L is
severely unbalanced
•
Check the connection between HD3L
and motor
•
Check the quality of motor
E0017 Controller
overload
•
Acc time is too short
•
Improper setting of V/f curve or
torque boost leads to over current
•
Mains supply voltage is too low
•
Motor load is too high
•
Adjust Acc time
•
Adjust V/f curve or torque boost
•
Check mains supply voltage
•
Use controller with proper power rating
E0018
Excessive speed
deviation
•
Brake fault or contactor fault
•
PG pulse number fault
•
Improper setting F05.19, F05.20
•
Inadequate controller torque
•
Speed-loop PI parameter setting
is incorrect
•
Change contactor
•
Set proper PG P/R
•
Correct the setting of F05.19, F05.20
•
Select HD3L with biger capacity
•
Correctly set speed-loop PI parameter
E0019 Motor
overload
•
Improper setting of V/f curve
•
Mains supply voltage is too low
•
Overload protection factor of
motor is not set properly
•
Motor locked-rotor or overload
