1. When fault alarm occurs, please take proper action according to the Table 6-1.
Table 6-1 Fault alarm description and counter-measures
Fault code
Fault name Possible reasons of fault Counter-measures
-Lu-
DC bus
undervoltage
• At the begining of power on
and at the end of power off
• Input voltage is too low
• Improper wiring leads to
undervoltage of hardware
• It is normal state of power on
and power off
• Please check input power
voltage
• Please check wiring and wire
properly
E001
DC bus
overvoltage
• Input voltage is too high
• Deceleartion time is too short
• Improper wiring leads to
overvoltage of hardware
• Please check power input
• Please set a proper value for
Dec time
• Please check wiring and wire
properly
E002
Controller output
instantaneous
overcurrent
(hardware)
• Improper connection between
controller and motor
• Improper motor parameters
• The encoder signal error
• Improper wiring leads to
overcurrent of hardware
• Acceleration/deceleration
time is too short
• Connect the controller and
motor properly
• Please set correct motor
parameters
• To ensure correct encoder
signal, check the encoder
connection
• Please check system wiring
and wire properly
• Please set proper Acc time and
Dec time
E003
Controller output
overcurrent
(software)
E004
Loss of Z phase
signal of
permanent
magnet
synchronous
motor encoder
• Without detecting the Z signal • Detect the encoder signal
E005
Machine type
mismatch
• YS-
(below V1.02)
• Use the new panel YS-P02 or
YS-P03
•
Alarm fault, the panel should
be reset one time
E006
Motor parameter
auto-tuning fault
• Motor rated parameters
improperly set
• Motor incorrect connection
• Encoder Z signal loss
• Set proper motor parameters
• Please check the motor’s
connection
• Please check the encoder
E007
Controller
overloaded
• The load is too big
• There are obstacles in door
machine
• Regulate the mechanical
• Check machinery, to exclude
obstacles
E008
Heatsink
overheated
•
The temperature detection
circuit is abnormal
• The outer vent is jammed
• Please contact the supplier for
repairing
• Check the outer vent
