Er5: Indicates that the lower control detects the abnormal phenomenon of motor overload
Er5 problem
solution
The current is too high for a sustained period.
The detection circuit of the lower control board fails.
Please check whether the power supply line is normal.
Replace the lower control, pending repair.
Er6：Indicates that the lower control detects the abnormal phenomenon of speed
Er6 problem
solution
The motor wire is not connected properly.
The detection circuit of the lower control board fails
or the motor is damaged.
Please reconnect the motor cable.
Replace lower control or motor, pending maintenance
Er7：Controller does not receive signal
Er99：Unmanned Shutdown
Er7 problem
solution
The communication line of the electronic watch is
not connected properly, broken, and poor contact.
The detection circuit of the lower control board fails.
Please reconnect the communication cable.
Replace the lower control, pending maintenance.
Er4: Indicates that the down-control motor over-current protection information prompt
Er4 problem
solution
The load of the walking machine exceeds the rated
operating current of the motor.
It is recommended to be within the rated operating
current range of the motor.
The lower control current limiting system is faulty.Replace the lower control, pending repair.
There is a problem with the assembly structure of
the walking machine and the motor, which causes
motor resistance or blockage.
Check whether the structure of the walking machine
is normal.
Er3: Indicates that the down-control motor overvoltage protection information prompts
Er3 problem
solution
The load of the walking machine exceeds the
rated working voltage of the motor.
The motor of the walking machine is abnormal/the
speed is too fast due to the failure of the light sensor.
The overvoltage detection circuit of the lower control
board fails.
Replace motor/replace photoelectric sensor.
Replace the lower control, pending repair.
It is recommended to use it within the rated operating
voltage range of the motor.
Er1: Indicates that the communication between the electronic watch and the electronic control is abnormal
Er1 problem
solution
The communication line of the electronic watch is
not connected properly, broken, poor contact.
Please reconnect the communication line
Electronic watch has no signal output.Replace the electronic watch, pending repair
Replace the lower control, pending maintenance No signal output under control
