Content
The number of sewing needles exceeds
the total number of stitches of the
current pattern.
The verification of the received order at
stepping board is failed
Large current is detected by hardware
The detected encoder response position
is not consistent with the position set in
the order.
The system will give this warning when
it detects the abnormal motor speed via
the encoder response signal.

Solution
Check whether the spindle motor and cable are
normal, and check whether the spindle encoder
is subject to external interference.
Check the connection of SPI communication
cable
At first, please check motor. Then check the
resistance and sensor value. If the motor is ok,
user should check the hardware on stepping
board
Change the stepping motor to open loop mode
and run it. If the motor can work normally, the
motor is ok. If the motor can't work normally,
user should check the driving part on the
stepping board and the motor itself. After the
above operations, user should check the
encoder. Make sure the connection and the
condition of the encoder cable is ok. And make
sure the signal response part on the stepping
board and the encoder itself is ok.
The checking method is the same with that for
Position Error
