Fault
Fault reasons
Counter-measures
E0015
Input voltage
phase loss
•
For three-phase input HD3N-L,
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 HD3N-L is
severely unbalanced
•
Check the connection between HD3N-L
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 F05.17, F05.18
•
Inadequate controller torque
•
Speed-loop PI parameter setting is
incorrect
•
Change contactor
•
Set proper PG P/R
•
Correct F05.17, F05.18
•
Select HD3N-L 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
•
Adjust V/f curve
•
Check the power input
•
Properly set the overload protection
factor of motor
•
Check the load and mechanical
transmission devices
E0020
Motor overheat
•
Motor overheat
•
Motor overheat terminal (DI)
connects incorrectly
•
The setting of motor paramteter is
incorrect
•
Reduce the load; Increase the Acc/Dec
time; Repaire or replace the motor
•
Detect whether the overheat detection
input signal is correct
•
Set the motor parameter according to
the nameplate
E0021
Read/write fault of
control board
EEPROM
•
Memory circuit fault of control
board EEPROM
•
Contact the supplier for repairing
E0022
Read/write fault of
keypad EEPROM
•
Memory circuit fault of keypad
EEPROM
•
Replace the keypad
•
Contact the supplier for repairing
E0023
Faulty setting of
parameters
•
The power rating between motor
and controller is too different
•
Improper setting of motor
parameters
•
Select a controller with suitable power
rating
•
Set correct value of motor parameters
E0024
External
equipment fault
•
Fault terminal of external
equipment operates
•
Check external equipment
E0025
Too small running
current
•
Improper setting of F17.00, F17.01
•
Correct the setting of F17.00, F17.01
•
Check the connection between HD3N-L
and motor
•
Detect HD3N-L whether output
•
Detect whether the output contactor
work is nomal
