Error Description Reason Solution
E686
Stepping closed ‐ loop
DSP1X25 is out of
track
The position detected by the
encoder isn’t accord with
the one in the program
The stepper motor to open loop mode, if can be
normal work, the motor is normal. If the machine
can't normally work, you may need to troubleshoot
step plate part and motor ontology. After finish the
above, troubleshoot the encoder part, to see if the
encoder cables plugged into the wrong, if stuck, is
there any encoder signal damaged or step plate
feedback signal damaged part or if encoder
ontology is normal.
E687
Stepping closed ‐ loop
DSP1X25 is
over ‐ speed
Over ‐ speed is detected Please refer to E686
E690
Stepping closed –loop
communication is
abnormal
DSP2(X21/X23)
Received instructions failed
checking
。
Please check if the SPI communication cable is
connected well or not.
E691
Stepping closed ‐ loop
DSP2X23 is overload
Overcurrent is detected
Please check if the motor is in good condition
through checking its resistance and inductance ,if it
is well, please check the stepping driving board
E692
Stepping closed ‐ loop
DSP2 first (X23) is
overloaded
The position detected by
feedback of encoder doesn’t
conform to instruction of
the procedure.
The stepper motor to open loop mode, if can be
normal work, the motor is normal. If the machine
can't normally work, you may need to troubleshoot
step plate part and motor ontology. After finish the
above, troubleshoot the encoder part, to see if the
encoder cables plugged into the wrong, if stuck, is
there any encoder signal damaged or step plate
feedback signal damaged part or if encoder
ontology is normal.
E693
Stepping closed ‐ loop
DSP2 first (X23) over
speed
The working rotate speed
abnormal is detected
through the feedback signal
from the encoder
The same test method with above
E695
Stepping closed ‐ loop
DSP2 first (X21) over
current
Hardware detect a large
current
First check whether the motor is normal, can
measure the resistance, inductance values if they
are within the normal range. If the motor is normal,
need to check if the stepping board hardware is
normal.
