Fault Reason Countermeasure
E0007
MONT20 overloaded
• Load of door motor is too large
• Door motor is resisted by obstacle
• Adjust the mechanical device
• Check mechanical device for anything
resisting it
E0008
Permanent magnet
Syn. motor first
current detection is
too small
• When the first power-on mode of
the permanent magnet Syn. motor
is selected as the pulse method
(F06.25 hundred = 1), the detected
current is too small
• Check the motor wiring and wire
properly
• Check if the door controller output is
normal
E0009
Motor overload fault
• Excessive load on door motor
• A foreign object blocked the door
motor
• Adjust mechanism
• Check mechanical devices to remove
foreign object
• Improper parameter setting of door
controller
E0010
Abnormal opening
fault
• The motor was blocked for 10
consecutive times
• Adjust mechanism
• Check mechanical device to remove
foreign object
• Improper parameter setting of door
controller
E0011
Motor overheating
fault
• External motor overheating signal is
detected
• Motor overheating switch action
E0012
Abnormal closing fault
• After the motor is powered on, the
CD complete signal is never
detected, and the number of CD
blocked exceeds 20 times
• Adjust mechanism
• Check mechanical devices to remove
foreign object
• Improper setting of door controller
parameters
E0014
Read/write fault of
controller EEPROM
• Memory circuit fault of controller
EEPROM
• Contact the supplier for repairing
E0015
Speed deviation is too
large
• In the range of F10.16, the actual
speed is greater than the given
speed and exceeds the set value of
F10.15
• Check if the F10.15 - F10.16 are set
properly
• Check encoder wiring
• Redo self-tuning
E0016
Overspeed fault
• The actual speed detected in the
range of F10.18 is greater than the
motor rated frequency F10.17
• Check if the F10.17 - F10.18 are set
properly
• Check encoder wiring
• Redo self-tuning
