Fault code Fault name Possible reasons of fault Counter-measures
E0010 Braking unit fault • Circuit fault of braking unit • Please seek technical support
E0011 CPU faulty • CPU abnormal
• Please detect at power on after
completely power outage
• Please seek technical support
E0012
Motor auto-tuning
fault
• Parameter auto-tuning is time
out
• Please check the motor’s
connection
• Input the correct nameplates
parameters
• Please seek technical support
E0013 Soft start failed
• Contactor fault
• Fault of control circuit
• Replace the contactor
• Please seek technical support
E0014
Current detect
faulty
• Current detection circuit is
damaged
• Please contact the supplier for
repairing
E0015 Lack of input
• For three-phase input
controller, input phase loss fault
occurs to power input
• Please check the three-phase
power input
• Please seek technical support
E0016 Lack of output
• Output phase disconnection or
loss
• Heavy imbalance of controller’s
three-phase load
• Please check the connection
between controller and motor
• Please check the quality of motor
E0017
Controller
overloaded
• Acceleration 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 acceleration time
• Adjust V/f curve or torque boost
• Please check mains supply
voltage
• Please use controller with proper
power rating
E0018
Excessive speed
deviation
• Brake fault or contactor fault
• PG pulse number fault
• Improper setting of F05.19 and
F05.20
• Inadequate controller torque
• Speed-loop PI parameter
setting isn’t correct
• Change contactor
• Set proper PG P/R
• Correct the setting of F05.19 and
F05.20
• Select biger capacity controller
• Correctly set speed-loop PI
parameter
E0019 Motor overload
• Improper setting of V/f curve
• Mains supply voltage is too low
• Motor’s overload protection
factor is not set properly
• Motor runs with blocked torque
or load is too heavy
• Adjust the setting of V/f curve
• Check the power input
• Please properly set the overload
protection factor of the motor
• Please check the load and
mechanical transmission devices
E0020 Motor overheat
• Motor overheat
• Motor overheat terminal (digital
or analogue input terminal)
incorrect connection
• The setting of motor
paramteters is incorrect
• Reduce the load; Increas the
acceleration/deceleration time;
Repaire or replace the motor
• Detect the overheat detection
input signal whether correct
• Set the motor parameter
according to the motor’s
nameplates
