motor
LED1 Green flash -------- MCU status see Table 2 See table 2
Table 2
LED Flash
Times
Status Action Condition Failure Parts
1 Normal
Flashing 1 time per second regularly. The
CPU works well
2
No Feedback from the
optical encoder
1)There is no optical encoder signal over 4
seconds on low speed (less than 4 miles)
2)There is no optical encoder signal over 1
second on high speed (more than 4 miles)
The encoder is failed or poor
connecting
3 Overload/overcurrent
The DC motor current is over the rated
current and keep for 4 seconds
The motor is over loaded
4 Overspeed
The motor control device is failed, or the
accelerated speed is too fast
MOSFET (IGBT) is damaged
5 Being rapidly stopped The safe key is off
6 No incline action
Incline motor is bock, there is no count
signal feedback in the movement
The incline motor control
device (relay) is failed, or the
incline motor is overheat
protection.
7
Communication abnormal
by AURT No communication with console, or not
obey the communication protocal
The uart circuit is failed, or
the connection line is
damaged
8 No incline motor Can’t find ZERO signal of the incline motor
There is no incline motor
connected or the zero
switch is damaged
