E0014: Current detection fault
Counter-measures
Fault subcode:
1401: Current detection failure
1402: U / W phase current
detection fault
1403: Current correction circuit
failure
Cause of issue:
1: Current detection circuit is
damaged
1: Contact factory to repair
E0015: Input phase loss
Counter-measures
Fault subcode:
1500: Input phase loss
Cause of issue:
1: For three-phase input drive
controller, three-phase input
power supply phase loss
1: Check three-phase input power supply
2: Seeking technical support
E0016: Output phase loss
Counter-measures
Fault subcode:
1600: Output phase loss
detected during operation
Counter-measures
1: Drive controller three-phase
output disconnected or missing
phase
2: The three-phase load of the
drive controller is seriously
unbalanced
1: Check the wiring between the drive
controller and the motor
2: Check the motor
E0017: Drive controller overload
Counter-measures
Fault subcode:
1600: Drive controller overload
Cause of issue:
1: Acc. time setting is too short
2: Improper setting of V/f curve or
torque boost causes excessive
current
3: The grid voltage is too low
4: The motor load is too large
1: Adjust the Acc. time
2: Adjust V/f curve or torque boost
3: Check the input grid voltage
4: Select power matching drive controller
E0018: Motor speed deviation is too large
Counter-measures
Fault subcode:
1801: Motor speed deviation is
too large
Cause of issue:
1: Brake failure or running
contactor failure
2: Encoder pulse number setting
error
3: F05.19, F05.20 setting is
unreasonable
4: Drive controller output torque
is insufficient
5: The speed loop PI parameter is
set incorrectly
1: Replace the fault contactor
2: Reasonably set the encoder pulse
parameters
3: Modify F05.19, F05.20 parameters
4: Select a larger capacity drive controller
5: Correctly set the speed loop PI parameter
E0019: Motor overload
Counter-measures
Fault subcode:
1900: Motor overload
Cause of issue:
1: V/f curve is set incorrectly
2: The grid voltage is too low
3: Improper setting of motor
overload protection factor
4: The motor is blocked or the
load is too large
1: Adjust the appropriate V/f curve
2: Check the input power
3: Reasonably set the motor overload
protection factor
4: Check load and mechanical transmission
